     * <p>The lens shading correction is defined as a full shading correction that

     * corrects both color shading for the output non-RAW images. After the

     * shading map is applied, the output non-RAW images will be flat-field images

     * for flat scenes under uniform illumination.</p>

     * shading correction map; when there is some lens shading correction applied

     * to the RAW output image (ACAMERA_SENSOR_INFO_LENS_SHADING_APPLIED <code>==</code> true),

     * this map reports the remaining lens shading correction map that needs to be

     * applied to get fully shading corrected images.</p>

     * <p>For a full shading correction map, the least shaded section of the image
