Abstract
The image capture device includes defect information storage unit in which defective pixel data is stored in advance; signal conversion unit adapted to covert pixel values of an image signal output from image capture unit to pixel values from which defective values are excluded; a defective pixel establishing unit, an image signal storage unit for storing defective values in terms of frame units chronologically and in order of address; and second comparison unit. The first comparison unit acquires defective pixel data in frame units in several increments from the defect information storage unit and compares the data with the image signal; once all of the defective pixel data has been acquired and compared, comparison of the image signal data and the defective pixel data will stop, and a comparison process will be carried out by the second comparison unit.
