Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for processing image data. One illustrative method of processing image data includes: capturing a first image of a subject using a variable aperture lens configured with a first aperture and a first exposure value; capturing a second image of the subject using the variable aperture lens configured with a second aperture and a second exposure value, wherein the second aperture is smaller than the first aperture and the second exposure value is smaller than the first exposure value; and generating a high dynamic range (HDR) image at least in part by fusing the first image and the second image fusing the first image and the second image.

Abstract: Methods, systems, and apparatuses are provide to perform automatic banding correction in captured images. For example, the methods receive from a plurality of sensing elements in a sensor array, first image data captured with a first exposure parameter, and second image data captured with a second exposure parameter. The methods partition first image data and second image data and determine values for each partition. The methods compute banding errors based on the determined values of the partitions for first image data and second image data. The methods also determine a banding error correction to one or more of first image data and second image data based on the banding errors. Further, the methods perform an automatic correction of the banding errors on one or more of first image data and second image based on the banding error correction.
