ABSTRACT:
A pixel compensation method is implemented by an image-capturing device having an image sensor for obtaining a pixel pattern of a plurality of pixels, in which each of the pixels has a response intensity. The pixel compensation method includes: a) selecting a first block of a predetermined number of pixels from the pixel pattern obtained by the image sensor; b) designating at least one pixel from the pixels of the first block as a stand-by compensation pixel; c) determining a first compensation value according to the response intensities of the pixels of the first block; and d) adjusting the response intensity of the stand-by compensation pixel according to the first compensation value.
