Defect correction and other de-noising as well as resolution maintenance and contour correction can all be appropriately performed in an image-signal processing device for processing an image signal from an image sensor. First through third de-noising parts 30a through 30c are provided separately to correspond to a brightness-processing part 36, a color-processing part 40, and a contour-processing part 38, respectively. Among defect-correcting parts 42a through 42c provided to the de-noising parts 30a through 30c, respectively, the defect-correcting part 42c provided to correspond to the contour-processing part 38 is set to a low defect-correction level and maintains contour information. The defect-correcting part 42a provided to correspond to the brightness-processing part 36 is set to an intermediate correction level and corrects pixel defects while maintaining resolution. The defect-correcting part 42b provided to correspond to the color-processing part 40 is set to a high correction level and appropriately removes pixel defects.
