PROBLEM TO BE SOLVED: To provide a pixel defect correcting device for properly correcting defective pixels even if they successively occur. SOLUTION: The pixel defect correcting device includes a defective pixel detecting means capable of correctly detecting defective pixels even if they successively occur by using, as reference pixels, eight pixels adjacent to a pixel of interest with this pixel as the center and calculating a relation among the largest pixel signal, the second largest pixel signal and the pixel signal of the pixel of interest; and a defective pixel correcting means for controlling defect correcting operations depending on their positional relation when the defective pixels are successively detected for suppressing erroneous correction. The pixel defect correcting device thus constituted can properly correct the defective pixels without erroneous correction even if they occur successively. COPYRIGHT: (C)2005,JPO&NCIPI
