Provided is a method for processing images. The method includes: acquiring a plurality of original sub-images acquired by a plurality of cameras in a camera array; converting first pixel coordinates of each pixel in each original sub-image in an image coordinate system into target pixel coordinates in a target plane coordinate system; determining a region pixel value of each sub-region according to a correspondence between the target pixel coordinates of each pixel in each original sub-image and each sub-region in the target plane; and determining a spliced image in the target plane based on the region pixel value of each sub-region.
