At the same time, the physical non-RAW streams' 8110 * field of view must not be smaller than the requested crop region and zoom ratio, as 8111 * long as it's within the physical lens' capability. For example, for a logical camera 8112 * with wide-tele lens configuration where the wide lens is the default, if the logical 8113 * camera's crop region is set to maximum size, and zoom ratio set to 1.0, the physical 8114 * stream for the tele lens will be configured to its maximum size crop region (no zoom).</p> 8115 * <p><em>Deprecated:</em> Prior to Android 11, the field of view of all non-RAW physical streams 8116 * cannot be larger than that of non-RAW logical streams. If the logical camera has a 8117 * wide-ultrawide lens configuration where the wide lens is the default, when the logical 8118 * camera's crop region is set to maximum size, the FOV of the physical streams for the 8119 * ultrawide lens will be the same as the logical stream, by making the crop region 8120 * smaller than its active array size to compensate for the smaller focal length.</p> 8121 * <p>Even if the underlying physical cameras have different RAW characteristics (such as 8122 * size or CFA pattern), a logical camera can still advertise RAW capability. In this 8123 * case, when the application configures a RAW stream, the camera device will make sure 8124 * the active physical camera will remain active to ensure consistent RAW output 8125 * behavior, and not switch to other physical cameras.</p> 8126 * <p>The capture request and result metadata tags required for backward compatible camera 8127 * functionalities will be solely based on the logical camera capabiltity. On the other 8128 * hand, the use of manual capture controls (sensor or post-processing) with a 8129 * logical camera may result in unexpected behavior when the HAL decides to switch 8130 * between physical cameras with different characteristics under the hood.
