自 2025 年 3 月 27 日起，我們建議您使用 android-latest-release 而非 aosp-main 建構及貢獻 AOSP。詳情請參閱「Android 開放原始碼計畫變更」。
廣色域擷取
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
對於搭載 Android 14 以上版本的裝置，Android 支援 Display P3 廣色域擷取功能。裝置可使用 ImageReader 類別，以 JPEG 格式擷取寬色域色彩圖片，而無須使用 10 位元 HDR。這項功能可讓裝置透過 SessionConfiguration 中的 setColorSpace 參數，向 Camera2 架構要求以廣色域色彩空間擷取相機畫面。
需求條件
如要支援廣色域擷取功能，裝置必須具備廣色域色彩功能的相機。
實作
如要支援 Display P3 廣色域擷取要求，請執行下列操作：
- 讀取
Stream.aidl 中的 colorSpace 欄位，並將其套用至輸出串流。
- 實作
android.request.availableColorSpaceProfilesMap 中繼資料項目。
- 在
android.request.availableCapabilities 中回報 COLOR_SPACE_PROFILES 功能。
如需支援 P3 廣色域擷取的相機 HAL 參考實作，請參閱 /hardware/google/camera/devices/EmulatedCamera/hwl/
configs/emu_camera_back.json 中的以下內容：
如要進一步瞭解 Camera HAL 中的寬廣色域擷取功能，請參閱 metadata_definitions.xml 中的以下值：
API
對於搭載 Android 14 以上版本且支援廣色域擷取功能的裝置，相機用戶端可以使用下列公開 API：
ColorSpace 參數的預期值會衍生自 ColorSpace.Named 類別。Android 14 支援 SRGB、DISPLAY_P3 和 BT2020_HLG。
驗證
如要驗證您是否已實作 Display P3 廣色域擷取支援功能，請執行下列測試。
CTS

執行 Camera Image Test Suite (ITS) 測試，驗證下列項目：
- 存在含有正確色度座標的 ICC 色彩描述檔
- 圖片包含超出 sRGB 色域的像素資料

Devices can capture wide\ngamut color images in JPEG format with the `ImageReader` class without\nusing [10-bit HDR](/docs/core/camera/10-bit-camera-output). This feature lets\ndevices\nrequest camera capture in a wide gamut color space to the Camera2 framework\nthrough the [`setColorSpace`](https://developer.android.com/reference/android/hardware/camera2/params/SessionConfiguration#setColorSpace(android.graphics.ColorSpace.Named)) parameter in `SessionConfiguration`.\n\nRequirements\n------------\n\nTo support wide gamut capture, the device must have access to a camera with wide\ngamut color capabilities.\n\nImplementation\n--------------\n\nTo support Display P3 wide gamut capture requests, do the following:\n\n- Read the `colorSpace` field in [`Stream.aidl`](https://android.googlesource.com/platform/hardware/interfaces/+/refs/heads/android16-release/camera/device/aidl/android/hardware/camera/device/Stream.aidl) and apply it to the output stream.\n- Implement the `android.request.availableColorSpaceProfilesMap` metadata entry.\n- Report the `COLOR_SPACE_PROFILES` capability in `android.request.availableCapabilities`.\n\nFor a reference Camera HAL implementation supporting P3 wide gamut capture,\nsee the following in `/hardware/google/camera/devices/EmulatedCamera/hwl/\nconfigs/emu_camera_back.json`:\n\n- [`android.request.availableCapabilities`](https://android.googlesource.com/platform/hardware/google/camera/+/refs/heads/android16-release/devices/EmulatedCamera/hwl/configs/emu_camera_back.json#183)\n- [`android.request.availableColorSpaceProfilesMap`](https://android.googlesource.com/platform/hardware/google/camera/+/refs/heads/android16-release/devices/EmulatedCamera/hwl/configs/emu_camera_back.json#211)\n\nFor further details on wide gamut capture in the Camera HAL, see the following\nvalues in `metadata_definitions.xml`:\n\n- [`availableColorSpaceProfiles`](https://android.googlesource.com/platform/system/media/+/refs/heads/android16-release/camera/docs/metadata_definitions.xml#7163)\n- [`availableColorSpaceProfilesMap`](https://android.googlesource.com/platform/system/media/+/refs/heads/android16-release/camera/docs/metadata_definitions.xml#7184)\n- [`COLOR_SPACE_PROFILES`](https://android.googlesource.com/platform/system/media/+/refs/heads/android16-release/camera/docs/metadata_definitions.xml#6610)\n\n### APIs\n\nFor devices running Android 14 or higher with support\nfor wide gamut capture, camera clients can use the following public APIs:\n\n- [`ColorSpaceProfiles`](https://developer.android.com/reference/android/hardware/camera2/params/ColorSpaceProfiles)\n- [`setColorSpace`](https://developer.android.com/reference/android/hardware/camera2/params/SessionConfiguration#setColorSpace(android.graphics.ColorSpace.Named))\n\nThe expected values for the `ColorSpace` parameter are derived from the\n[`ColorSpace.Named`](https://developer.android.com/reference/kotlin/android/graphics/ColorSpace.Named)\nclass. In Android 14, `SRGB`, `DISPLAY_P3`,\nand `BT2020_HLG` are supported.\n\nValidation\n----------\n\nTo validate your implementation of Display P3 wide gamut capture support, run\nthe following tests.\n\n### CTS\n\n- `android.hardware.camera2.cts.ExtendedCameraCharacteristicsTest#test8BitColorSpaceOutputCharacteristics`\n- `android.hardware.camera2.cts.ExtendedCameraCharacteristicsTest#test10BitColorSpaceOutputCharacteristics`\n- `android.hardware.camera2.cts.ExtendedCameraCharacteristicsTest#testColorSpaceProfileMap`\n- `android.hardware.camera2.cts.ImageReaderTest#testDisplayP3Jpeg`\n- `android.hardware.camera2.cts.ImageReaderTest#testDisplayP3JpegRepeating`\n- `android.hardware.camera2.cts.ImageReaderTest#testDisplayP3Heic`\n- `android.hardware.camera2.cts.ImageReaderTest#testDisplayP3HeicRepeating`\n\n### ITS\n\nRun the\n[Camera Image Test Suite (ITS)](/docs/compatibility/cts/camera-its)\ntests to validate the following:\n\n- Presence of an ICC profile with correct chromaticity coordinates\n- Image contains pixel data outside the sRGB gamut"]]
