Abstract:
1. A circuit for correction of white pixel defects for complementing a white pixel fault occurring in a pixel section constituted by solid-state imaging elements, comprising: a nearby pixel data holding section for holding pixel data of a predetermined target pixel constituting the pixel section and a nearby pixel near the target pixel; a nearby pixel lightness comparison section for comparing lightness of the target pixel with that of the nearby pixel; a comparison-determination section for determining based on a result of comparison by said nearby pixel lightness comparison section whether or not the target pixel is associated with a white pixel fault having a lightness higher than that of the nearby pixel by a predetermined value or more; and a complementary calculation section for performing a complementary calculation by using the pixel data of the target and nearby pixels held by said nearby pixel data holding section if it is judged by said comparison-determination section that the target pixel is associated with the white pixel fault.
