Abstract: This disclosure provides systems, methods, and devices for image signal processing that support image correction, including lens shading correction (LSC). In a first aspect, a method of image processing includes receiving first image data comprising a first image frame from a camera module; receiving one-dimensional lens shading correction (LSC) factors; and determining an output image frame based on the first image frame by: interpolating a plurality of correction values corresponding to two-dimensional locations of the first image frame by interpolating the one-dimensional lens shading correction (LSC) factors; and applying the plurality of correction values to corresponding locations of the first image frame, wherein applying the plurality of correction values corrects a lens shading effect of the camera module. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods, and devices for image signal processing that support high dynamic range (HDR) image processing. In a first aspect, a method of image processing includes receiving, by a processor, first image data comprising a plurality of image frames comprising at least a first image frame having a first bitwidth and a second image frame having a second bitwidth, wherein the plurality of image frames represent a same scene; and determining a processed image frame having an output bitwidth higher than the first bitwidth and higher than the second bitwidth, the processed image frame based on the plurality of image frames by combining the plurality of image frames to obtain the output bitwidth. Other aspects and features are also claimed and described.
