Starting March 27, 2025, we recommend using android-latest-release instead of aosp-main to build and contribute to AOSP. For more information, see Changes to AOSP.
Wide gamut capture
Stay organized with collections

For devices running Android 14 or higher, Android
provides support for Display P3 wide gamut capture. Devices can capture wide
gamut color images in JPEG format with the ImageReader class without
using 10-bit HDR. This feature lets
devices
request camera capture in a wide gamut color space to the Camera2 framework
through the setColorSpace parameter in SessionConfiguration.
Requirements
To support wide gamut capture, the device must have access to a camera with wide
gamut color capabilities.
Implementation
To support Display P3 wide gamut capture requests, do the following:
- Read the
colorSpace field in
Stream.aidl
and apply it to the output stream.
- Implement the
android.request.availableColorSpaceProfilesMap metadata
entry.
- Report the
COLOR_SPACE_PROFILES capability in
android.request.availableCapabilities.
For a reference Camera HAL implementation supporting P3 wide gamut capture,
see the following in /hardware/google/camera/devices/EmulatedCamera/hwl/
configs/emu_camera_back.json:
For further details on wide gamut capture in the Camera HAL, see the following
values in metadata_definitions.xml:
APIs
For devices running Android 14 or higher with support
for wide gamut capture, camera clients can use the following public APIs:
The expected values for the ColorSpace parameter are derived from the
ColorSpace.Named
class. In Android 14, SRGB, DISPLAY_P3,
and BT2020_HLG are supported.
Validation
To validate your implementation of Display P3 wide gamut capture support, run
the following tests.
CTS

ITS
Run the

tests to validate the following:
- Presence of an ICC profile with correct chromaticity coordinates
- Image contains pixel data outside the sRGB gamut
