Abstract:
1. A method for correcting a picked-up image signal of an image pickup apparatus, said image pickup apparatus comprising: a solid-state imaging device comprising a plurality of pixels which are arranged in a two-dimensional array formed in a surface portion of a semiconductor substrate, and an amplifier which is provided at said semiconductor substrate, and which amplifies signals that are detected by said plurality of pixels in accordance with an amount of incident light; and an image signal processing section which processes a signal output from said amplifier; the method comprising: for each of said plurality of pixels senses light emission produced when said amplifier operates, obtaining through said semiconductor substrate a signal amount as a correction amount, and subtracting the correction amount from a detection signal amount of a pixel which is output from said amplifier, to correct the detection signal amount, wherein the correction amount is obtained as a value dependent on a distance between said amplifier and said pixel, and wherein the correction amount is obtained as a value which is inversely proportional to a square of the distance between said amplifier and said pixel.
