  • Defective pixel detection and correction apparatus using target pixel and adjacent pixel data
    Patent number: 7280142
    Abstract: A solid-state imaging apparatus includes: a defective pixel detector (8) for extracting, from a signal output by a frame-reading solid-state image pickup element (2), pixel data for a target pixel for which a determination is to be made and pixel data for peripheral pixels thereof, and for employing pixel data for a pixel, selected from among the peripheral pixels, in the same filter as the target pixel, to determine whether the target pixel is a defective pixel; and a defective pixel correction circuit (9) for employing the pixel data for the peripheral pixels to correct pixel data for the defective pixel. With this configuration, the output signal of the defective pixel can be corrected without spreading the effect produced by the defective pixel to the peripheral pixels, and a natural image can be displayed.
