Abstract
This disclosure provides systems, methods, and devices for image processing that support enhanced variable aperture (VA) camera operations. In a first aspect, a method of image processing includes determining first image statistics for first image data representing a first scene captured at a first aperture; and determining whether the first image data satisfies a first criteria. When the first image data satisfies the first criteria, the image processing includes determining an updated lens shading correction (LSC) corresponding to the first aperture based on the first image statistics and on a current LSC corresponding to the first aperture; and determining a first output image frame based on the updated LSC and the first image data. Other aspects and features are also claimed and described.
