Abstract
A method for camera calibration, performed by a processing unit, at least contains: controlling a camera module to obtain a shooting image with a distortion; generating reference position information of a plurality of pixels of the shooting image, wherein the reference position information includes position information of the plurality of pixels after eliminating the distortion; storing the reference position information in a lookup table, wherein the lookup table contains entries and each entry stores reference position of one pixel; and adjusting an output from the camera module by using the lookup table.
