Abstract
Among defective pixels of an image sensor, defective pixels which need to be corrected are determined depending on the type and defect level for individual defective pixels and on image capturing conditions. Depending on the types of the defective pixels, the correspondences between the image capturing conditions and the defect levels of the defective pixels to be corrected are prepared in advance, thereby carrying out appropriate defective pixel correction in view of the fact that the dependence of the abnormal signal output level on the image capturing conditions differs depending on the type of defective pixel.
