Abstract:
1. A solid-state imaging device comprising: a pixel extracting circuit that extracts, from a pixel block with a target pixel as a center, a signal of the target pixel and signals of peripheral pixels as pixels for the same color as the target pixel; a signal level comparing circuit that compares levels among the signals of the peripheral pixels extracted by the pixel extracting circuit and outputs the signals of the peripheral pixels rearranged in the order of a signal level; a defect judging circuit that performs defect judgment on the target pixel in response to the signal of the target pixel and the signals of the peripheral pixels from the signal level comparing circuit; and a defect correcting circuit that performs defect correction on the target pixel in accordance with a result of the defect judgment in the defect judging circuit, wherein the pixel extracting circuit extracts each signal of first peripheral pixels as the peripheral pixels arranged with pixels for colors other than the color of the target pixel interposed between the first peripheral pixels and the target pixel, second peripheral pixels as the peripheral pixels disposed on extension lines in directions from the target pixel to the first peripheral pixels, and third peripheral pixels as the peripheral pixels disposed between the second peripheral pixels, and the signal level comparing circuit compares the levels among the signals of the first peripheral pixels, the levels among the signals of the second peripheral pixels, and the levels among the signals of the third peripheral pixels.
