PROBLEM TO BE SOLVED: To provide an image sensor having a compensation function for a defective pixel. SOLUTION: The image sensor includes a switching part 700 for switching out pixel data Pixel (i, j) corresponding to a present address from a line memory part 200, a defective pixel correcting part 600 for receiving data PIXEL [I, J] of surrounding pixels including the Pixel (i, j) from the memory 200 with a row address select signal RASS of the defective pixel, a column address signal DPCA of the defective pixel and an information signal LineEnd of a final column as control signals, receiving the Pixel (i, j) from the switching part 700 and outputting corrected pixel data PIXEL<SP>*</SP>[I, J], and an image signal processing part 300 for performing signal processing for improving performance of the image sensor. Since the image sensor does not use an EEPROM, its production yield is increased and its cost is reduced. COPYRIGHT: (C)2004,JPO&NCIPI
