IPC: H04N5/14
Filed: 1989-05-30
Abstract: PURPOSE:To correct uneven lightness properly and automatically in response to a timewise change of the uneven lightness or external disturbance light intensity with simple constitution by dividing a video signal with a low frequency component included in the video signal. CONSTITUTION:An image pickup device 1 picks up an object 2 and outputs its video signal, a video signal is inputted to a low pass filter and outputs a low frequency component included in the video signal. A divider 4 receives the video signal and the low frequency component and outputs a signal dividing the video signal with the low frequency component as the corrected video signal. Thus, the uneven lightness is corrected in real time to avoid the effect even when the timewise change in the uneven lightness and the external disturbance light intensity takes place.
