Abstract:
1. A pixel compensation method to be implemented by an image-capturing device having an image sensor for obtaining image frames each including a pixel pattern of a plurality of pixels, each of the pixels of the pixel pattern having a frequency response intensity, said pixel compensation method comprising: a) selecting a first block of a predetermined number of pixels within one image frame from the pixel pattern obtained by the image sensor, the predetermined number of pixels of the first block being less than a total number of pixels of the pixel pattern; 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 frequency response intensities of the pixels of the first block within the one image frame without referring to frequency response intensities of pixels of another image frame; and d) adjusting the frequency response intensity of the stand-by compensation pixel according to the first compensation value.
