PROBLEM TO BE SOLVED: To provide a signal correction method for effectively correcting a plurality of signals when they contain noise or the like respectively. SOLUTION: A picture signal is acquired from an image pickup device 2 in an RGB bayer array 2 by using two channels. The color signal of a B pixel is read through a channel. The color signal of an R pixel is read through the other channel. All averages of B pixel signal values and R pixel signal values located on a straight line 22 with a gradient k passing through the coordinate point of the R pixel signal value AO and the B pixel signal value BO at each point of interest are calculated by means of the coordinate system of the B pixel signal and the R pixel signal. The R pixel signal value AO and the B pixel signal value BO at the each point of interest are replaced with the calculated average values. COPYRIGHT: (C)2005,JPO&NCIPI
