Document Type and Number:
Japanese Patent JP5246851
Kind Code:
B2
Abstract:
A method for correcting a pixel defect of a solid-state image pickup device includes acquiring deviation of image signals obtained by imaging respective spectral lights at specific image pickup position or at vicinities of the specific image pickup position by image pickup device; comparing the deviation with a reference value; detecting a pixel defect in an image pickup device which has imaged one of the spectral lights based on the comparing result; and correcting a pixel defect. For each detected pixel defect, at least address in an image frame, deviation, and information specifying one of the spectral lights are stored, and a determination on a pixel defect correction is made based on the above information.
