Filed: 2007-11-27
Abstract: <P>PROBLEM TO BE SOLVED: To improve an image quality by making correction without affecting a normal video signal as a countermeasure to cope with a noise component that appears in a signal on the boundary of imaging areas.  <P>SOLUTION: A read area front-part noise detection circuit 44 detects a high frequency component by calculating a difference between a level of a target pixel and a level average value of both neighboring pixels before and behind the target pixel for video signals within the range of several front-part pixels in a read area.
