-     * and chroma noise. The sensor sensitivity gain can extend to higher values beyond

-     * processing to recover details in dark and bright areas of the image,and noise
-     * reduction at high sensitivity gain settings to manage the trade-off between light
-     * sensitivity and capture noise.</p>
-     * <p>This mode is restricted to two output surfaces. One output surface type can either
-     * be SurfaceView or TextureView. Another output surface type can either be MediaCodec
-     * or MediaRecorder. This mode cannot be used with a target FPS range higher than 30
-     * FPS.</p>
-     * <p>If the session configuration is not supported, the AE mode reported in the
