To obtain an image processing method in which a defective pixel address memory for static correction is not increased, and correction omission of a defective pixel or deterioration in resolution due to defective pixel correction does not occur.

With respect to a difference absolute value between an average signal value of a block with a predetermined size including a defective pixel detection target pixel and a signal value of the defective pixel detection target pixel, it is determined whether or not the defective pixel detection target pixel is a defective pixel with a first threshold and a second threshold which is larger than the first threshold (steps ST 1 to ST 6). Next, when the difference absolute value is larger than the first threshold and smaller than the second threshold, a defective pixel address is registered in a defective pixel address memory as a target for static correction, and when the difference absolute value is larger than the second threshold, a defective pixel is determined as a pixel to which dynamic correction is performed (steps ST 8 to ST 12).
