<P>PROBLEM TO BE SOLVED: To provide an image processor which accurately make black level corrections for an electronic camera having an imaging element where an interlaced read of three or more fields is made. <P>SOLUTION: The correction quantities can individually be set by making an OB pixel integrating circuit discriminate a field from a vertical synchronizing signal transmitted from a synchronizing signal generator, a horizontal line from a horizontal synchronizing signal, and the color of one pixel from a clock pulse. The correction quantities can be held in designated storage means respectively and a correction quantity corresponding to an effect pixel signal transferred from a DRAM to the OB correcting circuit is selected from a storage means and subtracted from the effective pixel signal to make accurate black level corrections. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
