Abstract:
An image calibration method includes: (a) sensing at least one target pixel of a sensing row from an effective pixel region of an image sensor to generate at least one target pixel value; (b) sensing at least one reference pixel of a shading region in the image sensor to generate a calibration value, wherein the reference pixel and the sensing row do not belong to the same row; and (c) referring to the calibration value to calibrate and output the target pixel value.
