Android Builders Weblog: What’s HDR?

Posted by John Reck – Software program Engineer

For Android builders, delivering distinctive visible experiences is a steady aim. Excessive Dynamic Vary (HDR) unlocks new prospects, providing the potential for extra vibrant and immersive content material. Applied sciences like UltraHDR on Android are significantly compelling, offering the advantages of HDR shows whereas sustaining essential backwards compatibility with SDR shows. On Android you should utilize HDR for each video and pictures.

Through the years, the time period HDR has been used to indicate quite a lot of associated, however finally distinct visible constancy options. Customers encounter it within the context of digital camera options (publicity fusion), or as a advertising and marketing time period in TV or monitor (“HDR succesful”). This conflates distinct options like wider colour gamuts, elevated bit depth or enhanced distinction with HDR itself.

From an Android Graphics perspective, HDR primarily signifies larger peak brightness functionality that extends past the traditional Commonplace Dynamic Vary. Different perceived advantages usually derive from requirements comparable to HDR10 or Dolby Imaginative and prescient which additionally embrace the utilization of wider colour areas, larger bit depths, and particular switch features.

On this article, we’ll set up the foundational colour rules, then deal with frequent myths, make clear HDR’s position within the rendering pipeline, and study how Android’s show applied sciences and APIs allow HDR expertise.

The elements of colour

Understanding HDR begins with defining the three major elements that type the displayed quantity of colour: bit depth, switch perform, and colour gamut. These describe the precision, scaling, and vary of the colour quantity, respectively.

Whereas a colour mannequin defines the format for encoding pixel values (e.g., RGB, YUV, HSL, CMYK, XYZ), RGB is usually assumed in a graphics context. The mix of a colour mannequin, a colour gamut, and a switch perform constitutes colour area. Examples embrace sRGB, Show P3, Adobe RGB, BT.2020, or BT.2020 HLG. Quite a few combos of colour gamut and switch perform are attainable, resulting in quite a lot of colour areas.

components of color include bit depth + transfer fn + color gamut + color model with the last three being within the color space

Elements of colour

Bit Depth

Bit depth defines the precision of colour illustration. A better bit depth permits for finer gradation between colour values. In trendy graphics, bit depth sometimes refers to bits per channel (e.g., an 8-bit picture makes use of 8 bits for every crimson, inexperienced, blue, and optionally alpha channel).

Crucially, bit depth doesn’t decide the general vary of colours (minimal and most values) a picture can characterize; that is set by the colour gamut and, in HDR, the switch perform. As a substitute, rising bit depth gives extra discrete steps inside that outlined vary, leading to smoother transitions and lowered visible artifacts comparable to banding in gradients.

5-bit

8-bit

8-bit color gradient showing smoother transition between color values

Though 8-bit is among the most typical codecs in widespread utilization, it’s not the one choice. RAW photographs may be captured at 10, 12, 14, or 16 bits. PNG helps 16 bits. Video games regularly use 16-bit floating level (FP16) as a substitute of integer area for intermediate render buffers. Trendy GPU APIs like Vulkan even assist 64-bit RGBA codecs in each integer and floating level varieties, offering as much as 256-bits per pixel.

Switch Operate

A switch perform defines the mathematical relationship between a pixel’s saved numerical worth and its closing displayed luminance or colour. In different phrases, the switch perform describes find out how to interpret the increments in values between the minimal and most. This perform is important as a result of the human visible system’s response to gentle depth is non-linear. We’re extra delicate to adjustments in luminance at low gentle ranges than at excessive gentle ranges. Due to this fact, a linear mapping from saved values to show luminance wouldn’t lead to an environment friendly utilization of the obtainable bits. There could be greater than vital precision within the brighter area and too little within the darker area with respect to what’s perceptual. The switch perform compensates for this non-linearity by adjusting the luminance values to match the human visible response.

Whereas some switch features are linear, most make use of advanced curves or piecewise features to optimize picture high quality for particular shows or viewing circumstances. sRGB, Gamma 2.2, HLG, and PQ are frequent examples, every prioritizing bit allocation in a different way throughout the luminance vary.

Shade Gamut

Shade gamut refers back to the whole vary of colours {that a} explicit colour area or gadget can precisely reproduce. It’s sometimes a subset of the seen colour spectrum, which encompasses all the colours that the human eye can understand. Every colour area (e.g., sRGB, Show P3, BT2020) defines its personal distinctive gamut, establishing the boundaries for colour illustration.

A wider gamut signifies that the colour area can show a better number of colours, resulting in richer and extra vibrant photographs. Nevertheless, merely having a bigger gamut would not at all times assure higher colour accuracy or a extra vibrant outcome. The gadget or medium used to show the colours should even be able to reproducing the total vary of the gamut. When a show encounters colours exterior its reproducible gamut, the standard dealing with technique is clipping. That is to make sure that in-gamut colours are correctly preserved for accuracy, as in any other case makes an attempt to scale the colour gamut might produce disagreeable outcomes, significantly in areas through which human imaginative and prescient is especially delicate like pores and skin tones.

HDR myths and realities

With an understanding of what kinds the fundamental working colour rules, it’s now time to guage a few of the frequent claims of HDR and the way they apply in a normal graphics context.

Declare: HDR presents extra vibrant colours

This declare comes from HDR video sometimes utilizing the BT2020 colour area, which is certainly a large colour quantity. Nevertheless, there are a number of issues with this declare as a blanket assertion.

The primary is that photographs and graphics have been ready to make use of wider colour gamuts, comparable to Show P3 or Adobe RGB, for fairly a very long time now. This isn’t a singular development that was coupled to HDR. In JPEGs for instance that is outlined by the ICC profile, which dates again to the early Nineteen Nineties, though wide-spread adoption of ICC profile dealing with is considerably more moderen. Equally on the graphics rendering facet the utilization of wider colour areas is absolutely decoupled from whether or not or not HDR is getting used.

The second is that not all HDR movies even use such a wider gamut in any respect. Though HDR10 specifies the utilization of BT2020, different HDR codecs have since been created that don’t use such a large gamut.

The most important situation, although, is considered one of capturing and displaying. Simply because the format permits for the colour gamut of BT2020 doesn’t imply that your complete gamut is definitely usable in follow. For instance present Dolby Imaginative and prescient mastering pointers solely require a 99% protection of the P3 gamut. Which means that even for high-end skilled content material, it’s not anticipated that the authoring of content material past that of Show P3 is feasible. Equally, the overwhelming majority of shopper shows immediately are solely able to displaying both sRGB or Show P3 colour gamuts. On condition that the standard advice of out-of-gamut colours is to clip them, which means that regardless that HDR10 permits for as much as BT2020 gamut, the widest gamut in follow continues to be going to be P3.

Thus this declare ought to actually be thought of one thing supplied by HDR video profiles when in comparison with SDR video profiles particularly, though SDR movies may use wider gamuts if desired with out utilizing an HDR profile.

Declare: HDR presents extra distinction / higher black element

One of many advantages of HDR typically claimed is darkish blacks (e.g. Dolby Imaginative and prescient Demo #3 – Core Universe – 4K HDR or “Darkish scenes come alive with darker darks” ) or extra element at nighttime areas. That is even mirrored in BT.2390: “HDR additionally permits for decrease black ranges than conventional SDR, which was sometimes within the vary between 0.1 and 1.0 cd/m2 for cathode ray tubes (CRTs) and is now within the vary of 0.1 cd/m2 for most traditional SDR liquid crystal shows (LCDs).” Nevertheless, in actuality no show makes an attempt to indicate something however SDR black because the blackest black the show is bodily able to. Thus there is no such thing as a distinction between HDR or SDR when it comes to how darkish it could possibly attain – each backside out on the similar darkish stage on the identical show.

As for distinction ratio, as that’s the ratio between the brightest white and the darkest black, it’s overwhelmingly influenced by how darkish a show can get. With the prevalence of OLED shows, significantly within the cell area, each SDR and HDR have the identical distinction ratio consequently, as they each have basically excellent black ranges giving them infinite distinction ratios.

The PQ switch perform does allocate extra bits to the darkish area, so in idea it could possibly convey higher black element. Nevertheless, it is a distinctive side of PQ moderately than a characteristic of HDR. HLG is more and more the extra frequent HDR format as it’s most well-liked by cell cameras in addition to a number of excessive finish cameras. And whereas PQ might include this element, that doesn’t imply the HDR show can essentially show it anyway, as mentioned in Show Realities.

Declare: HDR presents larger bit depth

This declare comes from HDR10 and a few, however not all, Dolby Imaginative and prescient profiles utilizing 10 or 12-bits for the video stream. Just like extra vibrant colours, that is actually simply a facet of explicit video profiles moderately than one thing HDR itself inherently gives or is coupled to HDR. The utilization of 10-bits or extra is in any other case not unusual in imaging, significantly within the larger finish images world, with RAW and TIFF picture codecs able to having 10, 12, 14, or 16-bits. Equally, PNG helps 16-bits, though that’s hardly ever used.

Declare: HDR presents larger peak brightness

This then, is all that HDR actually is. However what does “larger peak brightness” actually imply? In any case, SDR shows have been pushing ever rising brightness ranges earlier than HDR was important, significantly for daylight viewing. And even with out that, what’s the distinction between “HDR” and simply “SDR with the brightness slider cranked up”? The reply is that we outline “HDR” as having a brightness vary greater than SDR, and we consider SDR as being the vary pushed by autobrightness to be comfortably readable within the present ambient circumstances. Thus we outline HDR when it comes to issues like “HDR headroom” or “HDR/SDR ratio” to point it’s a floating area relative to SDR. This makes brightness insurance policies simpler to motive about. Nevertheless, it does complicate the interplay with conventional HDR comparable to that utilized in video, particularly HLG and PQ content material.

PQ/HLG switch features

PQ and HLG characterize the 2 most typical approaches to HDR when it comes to video content material. They characterize two switch features that characterize totally different ideas of what’s “HDR.” PQ, revealed as SMPTE ST 2084:2014, is outlined when it comes to absolute nits within the show. The expectation is that it encodes from 0 to 10,000 nits, and expects to be mastered for a selected reference viewing atmosphere. HLG takes a special method, as a substitute opting to take a typical gamma curve for a part of the vary earlier than switching to logarithmic for the brighter portion. This has a claimed nominal peak brightness of 1000 nits within the reference atmosphere, though it’s not outlined in absolute luminance phrases like PQ is.

Trade-wide specs have not too long ago formalized the brightness vary of each PQ- and HLG-encoded content material in relation to SDR. ITU-R BT. 2408-8 defines the reference white stage for graphics to be 203 nits. ISO/TS 22028-5 and ISO/PRF 21496-1 have adopted go well with; 21496-1 particularly defines HDR headroom when it comes to nominal peak luminance, relative to a diffuse white luminance at 203 nits.

The realities of contemporary shows, mentioned under, in addition to typical viewing environments imply that conventional HDR video are almost by no means displayed as supposed. A show’s HDR headroom might evaporate underneath brilliant viewing circumstances, demanding an on-demand tonemapping into SDR. Conventional HDR video encodes a set headroom, whereas trendy shows make use of a dynamic headroom, leading to huge variations in video high quality even on the identical show.

Show Realities

To this point many of the dialogue round HDR has been from the angle of the content material. Nevertheless, customers eat content material on a show, which has its personal capabilities and extra importantly limits. A high-end cell show is prone to have traits comparable to gamma 2.2, P3 gamut, and a peak brightness of round 2000 nits. If we then think about one thing like HDR10 there are mismatches in bit utilization prioritization:

    • PQ’s elevated bit allocation on the decrease ranges finally ends up being wasted
    • The utilization of BT2020 finally ends up spending bits on components of a gamut that may by no means be displayed
    • Encoding as much as 10,000 nits of brightness is equally headroom that’s not utilized

These mismatches will not be inherently an issue, nevertheless, but it surely implies that as 10-bit shows grow to be extra frequent the prevailing 10-bit HDR video profiles are unable to truly benefit from the total show’s capabilities. Thus HDR video profiles are ready of concurrently being ahead wanting whereas additionally already being unable to maximise a present 10-bit show’s capabilities. That is the place know-how comparable to Extremely HDR or gainmaps typically present a compelling different. Regardless of typically utilizing an 8-bit base picture, as a result of the achieve layer that transforms it to HDR is specialised to the content material and its explicit vary wants it’s extra environment friendly with its bit utilization, resulting in outcomes that also look gorgeous. And as that base picture is upgraded to 10-bit with newer picture codecs comparable to AVIF, the efficient bit utilization is even higher than these of typical HDR video codecs. Thus these approaches don’t characterize evolutionary or stepping stones to “true HDR”, however moderately are additionally an enchancment on HDR along with having higher backwards compatibility. Equally Android’s UI toolkit’s utilization of the extendedRangeBrightness API truly nonetheless primarily occurs in 8-bit area. As a result of the rendering is tailor-made to the particular show and present circumstances it’s nonetheless attainable to have an excellent HDR expertise regardless of the utilization of RGBA_8888.

Unlocking HDR on Android: Subsequent steps

Excessive Dynamic Vary (HDR) presents development in visible constancy for Android builders, transferring past the normal constraints of Commonplace Dynamic Vary (SDR) by enabling larger peak brightness.

By understanding the core elements of colour – bit depth, switch perform, and colour gamut – and debunking frequent myths, builders can leverage applied sciences like Extremely HDR to ship actually immersive experiences which are each visually gorgeous and backward suitable.

In our subsequent article, we’ll delve into the nuances of HDR and consumer intent, exploring find out how to optimize your content material for various show capabilities and viewing environments.

Amplifying AI Readiness within the DoD Workforce


AI readiness is a longtime precedence for the Division of Protection workforce, together with preparation of the workforce to make use of and combine knowledge applied sciences and synthetic intelligence capabilities into skilled and warfighting practices. One problem with figuring out staff educated in knowledge/AI areas is the dearth of formal certifications held by staff. Employees can develop related data and abilities utilizing non-traditional studying paths, and because of this civilian and federal organizations can overlook certified candidates. Employees could select to domesticate experience on their very own time with on-line sources, private initiatives, books, and so on., in order that they’re ready for open positions even once they lack a level or different conventional certification.

The SEI’s Synthetic Intelligence Division is working to deal with this problem. We not too long ago partnered with the Division of the Air Power Chief Information and AI Workplace (DAF CDAO) to develop a technique to determine and assess hidden workforce expertise for knowledge and AI work roles. The collaboration has had some vital outcomes, together with (1) a Information/AI Cyber Workforce Rubric (DACWR) for evaluation of abilities recognized inside the DoD Cyberworkforce Framework, (2) prototype assessments that seize a knowledge science pipeline (knowledge processing, mannequin creation, and reporting), and (3) a proof-of-concept platform, SkillsGrowth, for staff to construct profiles of their experience and evaluation efficiency and for managers to determine the info/AI expertise they want. We element under the advantages of those outcomes.

A Information/AI Cyber Workforce Rubric to Improve Usability of the DoD Cyber Workforce Improvement Framework

The DoD Cyber Workforce Framework (DCWF) defines knowledge and AI work roles and “establishes the DoD’s authoritative lexicon primarily based on the work a person is performing, not their place titles, occupational collection, or designator.” The DCWF supplies consistency when defining job positions since totally different language could also be used for a similar knowledge and AI educational and trade practices. There are 11 knowledge/AI work roles, and the DCWF covers a variety of AI disciplines (AI adoption, knowledge analytics, knowledge science, analysis, ethics, and so on.), together with the data, abilities, talents, and duties (KSATs) for every work function. There are 296 distinctive KSATs throughout knowledge and AI work roles, and the variety of KSATs per work function varies from 40 (knowledge analyst) to 75 (AI check & analysis specialist), the place most KSATs (about 62 p.c) seem in a single work function. The KSAT descriptions, nonetheless, don’t distinguish ranges of efficiency or proficiency.

The info/AI cyber workforce rubric that we created builds on the DCWF, including ranges of proficiency, defining fundamental, intermediate, superior, and professional proficiency ranges for every KSAT.

figure1_06242025

Determine 1: An Excerpt from the Rubric

Determine 1 illustrates how the rubric defines acceptable efficiency ranges in assessments for one of many KSATs. These proficiency-level definitions help the creation of knowledge/AI work role-related assessments starting from conventional paper-and-pencil exams to multimodal, simulation-based assessments. The rubric helps the DCWF to offer measurement choices {of professional} follow in these work roles whereas offering flexibility for future modifications in applied sciences, disciplines, and so on. Measurement in opposition to the proficiency ranges may give staff perception into what they will do to enhance their preparation for present and future jobs aligned with particular work roles. The proficiency-level definitions can even assist managers consider job seekers extra constantly. To determine hidden expertise, it is very important characterize the state of proficiency of candidates with some affordable precision.

Addressing Challenges: Confirming What AI Employees Know

Potential challenges emerged because the rubric was developed. Employees want a way to exhibit the flexibility to use their data, no matter the way it was acquired, together with by non-traditional studying paths corresponding to on-line programs and on-the-job talent growth. The evaluation course of and knowledge assortment platform that helps the evaluation should respect privateness and, certainly, anonymity of candidates – till they’re able to share data relating to their assessed proficiency. The platform ought to, nonetheless, additionally give managers the flexibility to find wanted expertise primarily based on demonstrated experience and profession pursuits.

This led to the creation of prototype assessments, utilizing the rubric as their basis, and a proof-of-concept platform, SkillsGrowth, to offer a imaginative and prescient for future knowledge/AI expertise discovery. Every evaluation is given on-line in a studying administration system (LMS), and every evaluation teams units of KSATs into no less than one competency that displays every day skilled follow. The aim of the competency groupings is pragmatic, enabling built-in testing of a associated assortment of KSATs relatively than fragmenting the method into particular person KSAT testing, which might be much less environment friendly and require extra sources. Assessments are meant for basic-to-intermediate degree proficiency.

4 Assessments for Information/AI Job Expertise Identification

The assessments observe a fundamental knowledge science pipeline seen in knowledge/AI job positions: knowledge processing, machine studying (ML) modeling and analysis, and outcomes reporting. These assessments are related for job positions aligned with the info analyst, knowledge scientist, or AI/ML specialist work roles. The assessments additionally present the vary of evaluation approaches that the DACWR can help. They embrace the equal of a paper-and-pencil check, two work pattern exams, and a multimodal, simulation expertise for staff who might not be comfy with conventional testing strategies.

On this subsequent part, we define a number of of the assessments for knowledge/AI job expertise identification:

  • The Technical Expertise Evaluation assesses Python scripting, querying, and knowledge ingestion. It accomplishes this utilizing a piece pattern check in a digital sandbox. The check taker should test and edit simulated personnel and gear knowledge, create a database, and ingest the info into tables with particular necessities. As soon as the info is ingested, the check taker should validate the database. An automatic grader supplies suggestions (e.g., if a desk identify is wrong, if knowledge shouldn’t be correctly formatted for a given column, and so on.). As proven in Determine 2 under, the evaluation content material mirrors real-world duties which might be related to the first work duties of a DAF knowledge analyst or AI specialist.

figure2_06242025

Determine 2: Making a Database within the Technical Expertise Evaluation

  • The Modeling and Simulation Evaluation assesses KSATs associated to knowledge evaluation, machine studying, and AI implementation. Just like the Technical Expertise Evaluation, it makes use of a digital sandbox atmosphere (Determine 3). The primary job within the Modeling and Simulation Evaluation is to create a predictive upkeep mannequin utilizing simulated upkeep knowledge. Check takers use Python to construct and consider machine studying fashions utilizing the scikit-learn library. Check takers could use no matter fashions they need, however they have to obtain particular efficiency thresholds to obtain the best rating. Automated grading supplies suggestions upon resolution submission. This evaluation displays fundamental modeling and analysis that may be carried out by staff in knowledge science, AI/ML specialist, and presumably knowledge analyst-aligned job positions.

figure3_06242025

Determine 3: Making ready Mannequin Creation within the Modeling and Simulation Evaluation

  • The Technical Communication Evaluation focuses on reporting outcomes and visualizing knowledge, concentrating on each technical and non-technical audiences. It is usually aligned with knowledge analyst, knowledge scientist, and different associated work roles and job positions (Determine 4). There are 25 questions, and these are framed utilizing three query varieties – a number of alternative, assertion choice to create a paragraph report, and matching. The query content material displays widespread knowledge analytic and knowledge science practices like explaining a time period or end in a non-technical method, choosing an applicable approach to visualize knowledge, and making a small story from knowledge and outcomes.

figure4_06242025

Determine 4: Making a Paragraph Report within the Technical Communications Evaluation

  • EnGauge, a multimodal expertise, is an alternate strategy to the Technical Expertise and Technical Communication assessments that gives analysis in an immersive atmosphere. Check takers are evaluated utilizing real looking duties in contexts the place staff should make choices about each the technical and interpersonal necessities of the office. Employees work together with simulated coworkers in an workplace atmosphere the place they interpret and current knowledge, consider outcomes, and current data to coworkers with totally different experience (Determine 5). The check taker should assist the simulated coworkers with their analytics wants. This evaluation strategy permits staff to point out their experience in a piece context.

Determine 5: Working with a Simulated Coworker within the EnGauge Multimodal Evaluation

A Platform for Showcasing and Figuring out Information/AI Job Expertise

We developed the SkillsGrowth platform to additional help each staff in showcasing their expertise and managers in figuring out staff who’ve needed abilities. SkillsGrowth is a proof-of-concept system, constructing on open-source software program, that gives a imaginative and prescient for a way these wants will be met. Employees can construct a resume, take assessments to doc their proficiencies, and fee their diploma of curiosity in particular abilities, competencies, and KSATs. They’ll seek for roles on websites like USAJOBS.

SkillsGrowth is designed to exhibit instruments for monitoring the KSAT proficiency ranges of staff in real-time and for evaluating these KSAT proficiency ranges in opposition to the KSAT proficiencies required for jobs of curiosity. SkillsGrowth can be designed to help use circumstances corresponding to managers looking out resumes for particular abilities and KSAT proficiencies. Managers can even assess their groups’ knowledge/AI readiness by viewing present KSAT proficiency ranges. Employees can even entry assessments, which might then be reported on a resume.

In brief, we suggest to help the DCWF by the Information/AI Cyber Workforce Rubric and its operationalization by the SkillsGrowth platform. Employees can present what they know and make sure what they know by assessments, with the info managed in a method that respects privateness considerations. Managers can discover the hidden knowledge/AI expertise they want, gauge the info/AI talent degree of their groups and extra broadly throughout DoD.

SkillsGrowth thus demonstrates how a sensible profiling and evaluative system will be created utilizing the DCWF as a basis and the CWR as an operationalization technique. Assessments inside the DACWR are primarily based on present skilled practices, and operationalized by SkillsGrowth, which is designed to be an accessible, easy-to-use system.

Searching for Mission Companions for Information/AI Job Expertise Identification

We are actually at a stage of readiness the place we’re looking for mission companions to iterate, validate, and increase this effort. We want to work with staff and managers to enhance the rubric, evaluation prototypes, and the SkillsGrowth platform. There’s additionally alternative to construct out the set of assessments throughout the info/AI roles in addition to to create superior variations of the present evaluation prototypes.

There’s a lot potential to make figuring out and growing job candidates simpler and environment friendly to help AI and mission readiness. If you’re keen on our work or partnering with us, please ship an e mail to information@sei.cmu.edu.

Measuring data, abilities, means, and job success for knowledge/AI work roles is difficult. It is very important take away boundaries in order that the DoD can discover the info/AI expertise it wants for its AI readiness targets. This work creates alternatives for evaluating and supporting AI workforce readiness to realize these targets.
