Abstract

PURPOSE:To facilitate the confirmation of a trimming range by changing the brightness at the outside of the range of trimming in displaying the trimming range by an electronic view finder. CONSTITUTION:A video signal from an image pickup element 1 such as a CCD is fed to a display element 5 via an A/D converter 2, a video signal conversion circuit 3, and an A/D converter 4 and visualized. An address generating circuit 6 generates an address to a video signal conversion circuit 3. In turning on a switch 9, the video signal conversion circuit 3 outputs the video signal in the state of automatic gain control in the trimming range of a video image on the display element 5 and outputs a video signal whose brightness is changed from the state with automatic gain control at the outside of the video image trimming.
