Abstract
A method of correcting image data of an image sensor provided herein includes collecting a process window from the image sensor; obtaining weight factors of the process window in various directions based on readout values of the second photodiodes in the process window; obtaining interpolated values of the second photodiodes at positions of the first photodiodes in the first pixel groups in the process window by using the weight factors; and estimating a corrected value Bof a target first photodiode by an equation I: B=G×(B/G), wherein Gis the interpolated value of the second photodiodes at a position of the target first photodiode, Bis a mean of readout values of first photodiodes in a corresponding first pixel group including the target first photodiode and Gis a mean of the interpolated values of the second photodiodes at positions of the first photodiodes in the corresponding first pixel group.
