Abstract: This disclosure provides systems, methods, and devices for image signal processing that support compensating for a diffraction pattern in an image. The diffraction pattern results from blades of a variable aperture of a camera used to capture the image. In a first aspect, a method of image processing includes receiving, by a processor, first image data; determining, by the processor, a characteristic of the first image data correlated with a color temperature of the first image data; determining, by the processor, a compensation matrix based on whether the characteristic exceeds a predetermined threshold, wherein the compensation matrix comprises correction values for reducing red channel peaks in the first image data; and determining, with the computing device, corrected image data based on the first image data and on the compensation matrix. Other aspects and features are also claimed and described.
