Abstract
An image defect correction apparatus that processes luminance signals output from two-dimensionally arranged light-sensitive elements via a plurality of vertical charge coupled devices and a horizontal charge coupled device in a predetermined order, outputs image information, and includes: a recording unit that records therein an X address for identifying a correction-target vertical line of pixels corresponding to a vertical charge coupled device in which a point defect exists; a correction value calculating unit that calculates a correction value from values of (i) a luminance signal corresponding to at least one pixel at a predetermined position on the correction-target vertical line identified by the X address and (ii) a luminance signal corresponding to at least one pixel at a predetermined position on another vertical line; and a correcting unit that corrects values of luminance signals corresponding to the correction-target vertical line, based on the calculated correction value.
