Image processing for aperture size transition in a variable aperture (VA) camera

An apparatus, comprising:

• a memory storing processor-readable code;
• and
• at least one processor coupled to the memory, the at least one processor configured to execute the processor-readable code to cause the at least one processor to perform operations including:
• receiving first image data, from a variable aperture (VA) camera, acquired at a first aperture size;
• determining a first set of output image frames based on the first image data;
• determining first image statistics for the first image data;
• receiving second image data, from the VA camera, acquired during an aperture size transition;
• determining second image statistics for the second image data;
• and
• determining a second set of output image frames based on the first image data and the second image data, wherein determining the second set of output image frames comprises adjusting a characteristic of the second image data based on the first image data, the first image statistics, and the second image statistics.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

• receiving first image data from a variable aperture (VA) camera acquired at a first aperture size;
• determining a first set of output image frames based on the first image data;
• determining first image statistics for the first image data;
• receiving second image data from the VA camera acquired during an aperture size transition;
• determining second image statistics for the second image data;
• and
• determining a second set of output image frames based on the first image data and the second image data, wherein determining the second set of output image frames comprises adjusting a characteristic of the second image data based on the first image data, the first image statistics, and the second image statistics.
