If not supported, devices API level 30 or higher will always 4424 * list only <code>ROTATE_AND_CROP_NONE</code>.</p> 4425 * <p>When <code>CROP_AUTO</code> is in use, and the camera API activates backward-compatibility mode, 4426 * several metadata fields will also be parsed differently to ensure that coordinates are 4427 * correctly handled for features like drawing face detection boxes or passing in 4428 * tap-to-focus coordinates. The camera API will convert positions in the active array 4429 * coordinate system to/from the cropped-and-rotated coordinate system to make the 4430 * operation transparent for applications. The following controls are affected:</p> 4431 * <ul> 4432 * <li>ACAMERA_CONTROL_AE_REGIONS</li> 4433 * <li>ACAMERA_CONTROL_AF_REGIONS</li> 4434 * <li>ACAMERA_CONTROL_AWB_REGIONS</li> 4435 * <li>android.statistics.faces</li> 4436 * </ul> 4437 * <p>Capture results will contain the actual value selected by the API; 4438 * <code>ROTATE_AND_CROP_AUTO</code> will never be seen in a capture result.</p> 4439 * <p>Applications can also select their preferred cropping mode, either to opt out of the 4440 * backwards-compatibility treatment, or to use the cropping feature themselves as needed. 4441 * In this case, no coordinate translation will be done automatically, and all controls 4442 * will continue to use the normal active array coordinates.</p> 4443 * <p>Cropping and rotating is done after the application of digital zoom (via either 4444 * ACAMERA_SCALER_CROP_REGION or ACAMERA_CONTROL_ZOOM_RATIO), but before each individual 4445 * output is further cropped and scaled. It only affects processed outputs such as 4446 * YUV, PRIVATE, and JPEG. It has no effect on RAW outputs.</p> 4447 * <p>When <code>CROP_90</code> or <code>CROP_270</code> are selected, there is a significant loss to the field of 4448 * view. For example, with a 4:3 aspect ratio output of 1600x1200, <code>CROP_90</code> will still 4449 * produce 1600x1200 output, but these buffers are cropped from a vertical 3:4 slice at the 4450 * center of the 4:3 area, then rotated to be 4:3, and then upscaled to 1600x1200. Only 4451 * 56.25% of the original FOV is still visible. In general, for an aspect ratio of <code>w:h</code>, 4452 * the crop and rotate operation leaves <code>(h/w)^2</code> of the field of view visible.

The application should check the physical capture result 10056 * metadata for how the physical streams are cropped or zoomed. More specifically, given 10057 * the physical camera result metadata, the effective horizontal field-of-view of the 10058 * physical camera is:</p> 10059 * <pre><code>fov = 2 * atan2(cropW * sensorW / (2 * zoomRatio * activeArrayW), focalLength) 10060 * </code></pre> 10061 * <p>where the equation parameters are the physical camera's crop region width, physical 10062 * sensor width, zoom ratio, active array width, and focal length respectively. Typically 10063 * the physical stream of active physical camera has the same field-of-view as the 10064 * logical streams. However, the same may not be true for physical streams from 10065 * non-active physical cameras. For example, if the logical camera has a wide-ultrawide 10066 * configuration where the wide lens is the default, when the crop region is set to the 10067 * logical camera's active array size, (and the zoom ratio set to 1.0 starting from 10068 * Android 11), a physical stream for the ultrawide camera may prefer outputting images 10069 * with larger field-of-view than that of the wide camera for better stereo matching 10070 * margin or more robust motion tracking. At the same time, the physical non-RAW streams' 10071 * field of view must not be smaller than the requested crop region and zoom ratio, as 10072 * long as it's within the physical lens' capability. For example, for a logical camera 10073 * with wide-tele lens configuration where the wide lens is the default, if the logical 10074 * camera's crop region is set to maximum size, and zoom ratio set to 1.0, the physical 10075 * stream for the tele lens will be configured to its maximum size crop region (no zoom).</p> 10076 * <p><em>Deprecated:</em> Prior to Android 11, the field of view of all non-RAW physical streams 10077 * cannot be larger than that of non-RAW logical streams. If the logical camera has a 10078 * wide-ultrawide lens configuration where the wide lens is the default, when the logical 10079 * camera's crop region is set to maximum size, the FOV of the physical streams for the 10080 * ultrawide lens will be the same as the logical stream, by making the crop region 10081 * smaller than its active array size to compensate for the smaller focal length.</p> 10082 * <p>For a logical camera, typically the underlying physical cameras have different RAW 10083 * capabilities (such as resolution or CFA pattern). There are two ways for the 10084 * application to capture RAW images from the logical camera:</p> 10085 * <ul> 10086 * <li>If the logical camera has RAW capability, the application can create and use RAW 10087 * streams in the same way as before. In case a RAW stream is configured, to maintain 10088 * backward compatibility, the camera device makes sure the default active physical 10089 * camera remains active and does not switch to other physical cameras. (One exception 10090 * is that, if the logical camera consists of identical image sensors and advertises 10091 * multiple focalLength due to different lenses, the camera device may generate RAW 10092 * images from different physical cameras based on the focalLength being set by the 10093 * application.) This backward-compatible approach usually results in loss of optical 10094 * zoom, to telephoto lens or to ultrawide lens.</li> 10095 * <li>Alternatively, if supported by the device, 10096 * <a href="https://developer.android.com/reference/android/hardware/camera2/MultiResolutionImageReader.html">MultiResolutionImageReader</a> 10097 * can be used to capture RAW images from one of the underlying physical cameras ( 10098 * depending on current zoom level). Because different physical cameras may have 10099 * different RAW characteristics, the application needs to use the characteristics 10100 * and result metadata of the active physical camera for the relevant RAW metadata.</li> 10101 * </ul> 10102 * <p>The capture request and result metadata tags required for backward compatible camera 10103 * functionalities will be solely based on the logical camera capability. On the other 10104 * hand, the use of manual capture controls (sensor or post-processing) with a 10105 * logical camera may result in unexpected behavior when the HAL decides to switch 10106 * between physical cameras with different characteristics under the hood. For example, 10107 * when the application manually sets exposure time and sensitivity while zooming in, 10108 * the brightness of the camera images may suddenly change because HAL switches from one 10109 * physical camera to the other.</p> 10110 * 10111 * @see ACAMERA_LENS_DISTORTION 10112 * @see ACAMERA_LENS_INFO_FOCUS_DISTANCE_CALIBRATION 10113 * @see ACAMERA_LENS_INFO_HYPERFOCAL_DISTANCE 10114 * @see ACAMERA_LENS_INFO_MINIMUM_FOCUS_DISTANCE 10115 * @see ACAMERA_LENS_INTRINSIC_CALIBRATION 10116 * @see ACAMERA_LENS_POSE_REFERENCE 10117 * @see ACAMERA_LENS_POSE_ROTATION 10118 * @see ACAMERA_LENS_POSE_TRANSLATION 10119 * @see ACAMERA_LOGICAL_MULTI_CAMERA_ACTIVE_PHYSICAL_ID 10120 * @see ACAMERA_LOGICAL_MULTI_CAMERA_SENSOR_SYNC_TYPE 10121 * @see ACAMERA_SENSOR_AVAILABLE_TEST_PATTERN_MODES 10122 * @see ACAMERA_SENSOR_BLACK_LEVEL_PATTERN 10123 * @see ACAMERA_SENSOR_CALIBRATION_TRANSFORM1 10124 * @see ACAMERA_SENSOR_CALIBRATION_TRANSFORM2 10125 * @see ACAMERA_SENSOR_COLOR_TRANSFORM1 10126 * @see ACAMERA_SENSOR_COLOR_TRANSFORM2 10127 * @see ACAMERA_SENSOR_FORWARD_MATRIX1 10128 * @see ACAMERA_SENSOR_FORWARD_MATRIX2 10129 * @see ACAMERA_SENSOR_INFO_COLOR_FILTER_ARRANGEMENT 10130 * @see ACAMERA_SENSOR_INFO_EXPOSURE_TIME_RANGE 10131 * @see ACAMERA_SENSOR_INFO_LENS_SHADING_APPLIED 10132 * @see ACAMERA_SENSOR_INFO_MAX_FRAME_DURATION 10133 * @see ACAMERA_SENSOR_INFO_PHYSICAL_SIZE 10134 * @see ACAMERA_SENSOR_INFO_SENSITIVITY_RANGE 10135 * @see ACAMERA_SENSOR_INFO_WHITE_LEVEL 10136 * @see ACAMERA_SENSOR_MAX_ANALOG_SENSITIVITY 10137 * @see ACAMERA_SENSOR_OPTICAL_BLACK_REGIONS 10138 * @see ACAMERA_SENSOR_REFERENCE_ILLUMINANT1 10139 * @see ACAMERA_SENSOR_REFERENCE_ILLUMINANT2 10140 */ 10141 ACAMERA_REQUEST_AVAILABLE_CAPABILITIES_LOGICAL_MULTI_CAMERA = 11, 10142 10143 /** 10144 * <p>The camera device is a monochrome camera that doesn't contain a color filter array, 10145 * and for YUV_420_888 stream, the pixel values on U and V planes are all 128.</p> 10146 * <p>A MONOCHROME camera must support the guaranteed stream combinations required for 10147 * its device level and capabilities.
