<P>PROBLEM TO BE SOLVED: To provide a defective pixel correcting method for preventing a defective pixel portion from being colored when the color around a defective pixel is pale or a colorless subject image is captured. Ž<P>SOLUTION: A defective pixel correcting circuit determines whether an incoming signal has been output from a defective pixel or from a normal pixel (S101). When it is output from the normal pixel, the incoming signal is output as an output image signal as it is (S102). When it is output from the defective pixel, it is determined whether the vicinity of the defective pixel is colored or colorless (S103). If the vicinity of the defective pixel is determined as colored, pre-interpolation is used (S104), while if determined as colorless, an image signal of another color component is used to generate an output image signal of the defective pixel so that an image at a position of the defective pixel becomes colorless (S105). Thus, a correction method can be provided for preventing a defective pixel portion from becoming colored if the surrounding color is pale or colorless. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
