The application should check the physical capture result 8885 * metadata for how the physical streams are cropped or zoomed. More specifically, given 8886 * the physical camera result metadata, the effective horizontal field-of-view of the 8887 * physical camera is:</p> 8888 * <pre><code>fov = 2 * atan2(cropW * sensorW / (2 * zoomRatio * activeArrayW), focalLength) 8889 * </code></pre> 8890 * <p>where the equation parameters are the physical camera's crop region width, physical 8891 * sensor width, zoom ratio, active array width, and focal length respectively. Typically 8892 * the physical stream of active physical camera has the same field-of-view as the 8893 * logical streams. However, the same may not be true for physical streams from 8894 * non-active physical cameras. For example, if the logical camera has a wide-ultrawide 8895 * configuration where the wide lens is the default, when the crop region is set to the 8896 * logical camera's active array size, (and the zoom ratio set to 1.0 starting from 8897 * Android 11), a physical stream for the ultrawide camera may prefer outputing images 8898 * with larger field-of-view than that of the wide camera for better stereo matching 8899 * margin or more robust motion tracking. At the same time, the physical non-RAW streams' 8900 * field of view must not be smaller than the requested crop region and zoom ratio, as 8901 * long as it's within the physical lens' capability. For example, for a logical camera 8902 * with wide-tele lens configuration where the wide lens is the default, if the logical 8903 * camera's crop region is set to maximum size, and zoom ratio set to 1.0, the physical 8904 * stream for the tele lens will be configured to its maximum size crop region (no zoom).</p> 8905 * <p><em>Deprecated:</em> Prior to Android 11, the field of view of all non-RAW physical streams 8906 * cannot be larger than that of non-RAW logical streams. If the logical camera has a 8907 * wide-ultrawide lens configuration where the wide lens is the default, when the logical 8908 * camera's crop region is set to maximum size, the FOV of the physical streams for the 8909 * ultrawide lens will be the same as the logical stream, by making the crop region 8910 * smaller than its active array size to compensate for the smaller focal length.</p> 8911 * <p>There are two ways for the application to capture RAW images from a logical camera 8912 * with RAW capability:</p> 8913 * <ul> 8914 * <li>Because the underlying physical cameras may have different RAW capabilities (such 8915 * as resolution or CFA pattern), to maintain backward compatibility, when a RAW stream 8916 * is configured, the camera device makes sure the default active physical camera remains 8917 * active and does not switch to other physical cameras. (One exception is that, if the 8918 * logical camera consists of identical image sensors and advertises multiple focalLength 8919 * due to different lenses, the camera device may generate RAW images from different 8920 * physical cameras based on the focalLength being set by the application.) This 8921 * backward-compatible approach usually results in loss of optical zoom, to telephoto 8922 * lens or to ultrawide lens.</li> 8923 * <li>Alternatively, to take advantage of the full zoomRatio range of the logical camera, 8924 * the application should use <a href="https://developer.android.com/reference/android/hardware/camera2/MultiResolutionImageReader.html">MultiResolutionImageReader</a> 8925 * to capture RAW images from the currently active physical camera. Because different 8926 * physical camera may have different RAW characteristics, the application needs to use 8927 * the characteristics and result metadata of the active physical camera for the 8928 * relevant RAW metadata.</li> 8929 * </ul> 8930 * <p>The capture request and result metadata tags required for backward compatible camera 8931 * functionalities will be solely based on the logical camera capability. On the other 8932 * hand, the use of manual capture controls (sensor or post-processing) with a 8933 * logical camera may result in unexpected behavior when the HAL decides to switch 8934 * between physical cameras with different characteristics under the hood. For example, 8935 * when the application manually sets exposure time and sensitivity while zooming in, 8936 * the brightness of the camera images may suddenly change because HAL switches from one 8937 * physical camera to the other.</p> 8938 * 8939 * @see ACAMERA_LENS_DISTORTION 8940 * @see ACAMERA_LENS_INFO_FOCUS_DISTANCE_CALIBRATION 8941 * @see ACAMERA_LENS_INFO_HYPERFOCAL_DISTANCE 8942 * @see ACAMERA_LENS_INFO_MINIMUM_FOCUS_DISTANCE 8943 * @see ACAMERA_LENS_INTRINSIC_CALIBRATION 8944 * @see ACAMERA_LENS_POSE_REFERENCE 8945 * @see ACAMERA_LENS_POSE_ROTATION 8946 * @see ACAMERA_LENS_POSE_TRANSLATION 8947 * @see ACAMERA_LOGICAL_MULTI_CAMERA_ACTIVE_PHYSICAL_ID 8948 * @see ACAMERA_LOGICAL_MULTI_CAMERA_SENSOR_SYNC_TYPE 8949 * @see ACAMERA_SENSOR_AVAILABLE_TEST_PATTERN_MODES 8950 * @see ACAMERA_SENSOR_BLACK_LEVEL_PATTERN 8951 * @see ACAMERA_SENSOR_CALIBRATION_TRANSFORM1 8952 * @see ACAMERA_SENSOR_CALIBRATION_TRANSFORM2 8953 * @see ACAMERA_SENSOR_COLOR_TRANSFORM1 8954 * @see ACAMERA_SENSOR_COLOR_TRANSFORM2 8955 * @see ACAMERA_SENSOR_FORWARD_MATRIX1 8956 * @see ACAMERA_SENSOR_FORWARD_MATRIX2 8957 * @see ACAMERA_SENSOR_INFO_COLOR_FILTER_ARRANGEMENT 8958 * @see ACAMERA_SENSOR_INFO_EXPOSURE_TIME_RANGE 8959 * @see ACAMERA_SENSOR_INFO_LENS_SHADING_APPLIED 8960 * @see ACAMERA_SENSOR_INFO_MAX_FRAME_DURATION 8961 * @see ACAMERA_SENSOR_INFO_PHYSICAL_SIZE 8962 * @see ACAMERA_SENSOR_INFO_SENSITIVITY_RANGE 8963 * @see ACAMERA_SENSOR_INFO_WHITE_LEVEL 8964 * @see ACAMERA_SENSOR_MAX_ANALOG_SENSITIVITY 8965 * @see ACAMERA_SENSOR_OPTICAL_BLACK_REGIONS 8966 * @see ACAMERA_SENSOR_REFERENCE_ILLUMINANT1 8967 * @see ACAMERA_SENSOR_REFERENCE_ILLUMINANT2 8968 */ 8969 ACAMERA_REQUEST_AVAILABLE_CAPABILITIES_LOGICAL_MULTI_CAMERA = 11, 8970 8971 /** 8972 * <p>The camera device is a monochrome camera that doesn't contain a color filter array, 8973 * and for YUV_420_888 stream, the pixel values on U and V planes are all 128.</p> 8974 * <p>A MONOCHROME camera must support the guaranteed stream combinations required for 8975 * its device level and capabilities.
