* camera's crop region is set to maximum size, the FOV of the physical streams for the
* ultrawide lens will be the same as the logical stream, by making the crop region
* smaller than its active array size to compensate for the smaller focal length.</p>
* <p>Even if the underlying physical cameras have different RAW characteristics (such as
* size or CFA pattern), a logical camera can still advertise RAW capability. In this
* case, when the application configures a RAW stream, the camera device will make sure
* the active physical camera will remain active to ensure consistent RAW output
* behavior, and not switch to other physical cameras.</p>
* <p>There are two ways for the application to capture RAW images from a logical camera
* with RAW capability:</p>
* <ul>
* <li>Because the underlying physical cameras may have different RAW capabilities (such
* as resolution or CFA pattern), to maintain backward compatibility, when a RAW stream
* is configured, the camera device makes sure the default active physical camera remains
* active and does not switch to other physical cameras. (One exception is that, if the
* logical camera consists of identical image sensors and advertises multiple focalLength
* due to different lenses, the camera device may generate RAW images from different
* physical cameras based on the focalLength being set by the application.) This
* backward-compatible approach usually results in loss of optical zoom, to telephoto
* lens or to ultrawide lens.</li>
* <li>Alternatively, to take advantage of the full zoomRatio range of the logical camera,
* the application should use <a href="https://developer.android.com/reference/android/hardware/camera2/MultiResolutionImageReader.html">MultiResolutionImageReader</a>
* to capture RAW images from the currently active physical camera. Because different
* physical camera may have different RAW characteristics, the application needs to use
* the characteristics and result metadata of the active physical camera for the
* relevant RAW metadata.</li>
* </ul>
* <p>The capture request and result metadata tags required for backward compatible camera
* functionalities will be solely based on the logical camera capabiltity. On the other
* functionalities will be solely based on the logical camera capability. On the other
* hand, the use of manual capture controls (sensor or post-processing) with a
* logical camera may result in unexpected behavior when the HAL decides to switch
* between physical cameras with different characteristics under the hood. For example,
