1. A pixel defect correction device for correcting a defect in any pixel in a group of pixels arranged as predetermined, comprising: defect detection means for detecting a defect in a focused pixel, using pixels surrounding the focused pixel; wherein the group of pixels are disposed on a single image sensor filtered by a color filter having two or more colors arranged in a predetermined array so that the group of pixels contain two or more color signals; line crawl determination means for determining the presence or absence of line crawl, a wavelength of light passing through one color of a filter that reaches a deeper site under a light receiving surface of an image sensor resulting in electric charge that appears as noise in adjacent pixels, around a defective pixel; correction means for correcting the defective pixel that uses pixels selected according to the presence or absence of a line crawl; and diagonal edge determination means for determining the presence or absence of a diagonal edge which includes, as a part thereof, the defective pixel; wherein when line crawl is present, the correction means corrects the defective pixel while using pixels selected according to the presence or absence of a diagonal edge.
