Method and apparatus for reducing fixed pattern noise of image sensor in digital domain
A method for reducing fixed pattern noise of an image sensor is provided. The method includes: accessing pixel data of at least one test frame in a test environment; and calculating/deriving average values of each column based on at least one portion of pixel data of the column in the at least one test frame, wherein the average values of columns are used as calibration values for calibrating image pixel data of columns when the image sensor operates in a normal light source environment.
