Patent ID: 7576787

Claim:
An image-pickup device which picks up an image, the image-pickup device comprising: a solid-image-pickup element operable to select a plurality of reading modes including an ordinary mode wherein signals of all of a plurality of pixels are read in sequence and at least one pixel-addition mode wherein signals of the plurality of pixels corresponding to filters of the same color are added to one another and output; defective-information-storage means which stores position information of a defective pixel on the solid-image-pickup element, where the defective pixel is detected when the ordinary mode is selected; signal-correction means which corrects a pixel signal of at least one picked-up-image signal obtained by the solid-image-pickup element based on the position information stored in the defective-information storage means, where the pixel signal corresponds to the position information; and position-information conversion means that converts the stored position information when the pixel-addition mode is selected, so that the converted position information agrees with information about an arrangement of pixels, the pixel-arrangement information corresponding to the picked-up-image signal generated in the pixel-addition mode, and that transmits the converted position information to the signal-correction means.
