Title: Method for compensating backlight of image pickup device
Inventor: WATANABE TORU
IPC: H04N5/217
Filed: 1988-03-18
Abstract: PURPOSE:To suppress the backlight around an aimed object so as to monitor a bright object image by comparing picture signals obtained from an image pickup element with inverted picture signals obtained by inverting the picture signals in level and replacing the picture signal part having higher luminance than the inverted picture signals with prescribed low-level signals. CONSTITUTION:Potential setting to one side input picture signals is performed at the 1st clamp circuit 51 and potential setting to the other side input picture signals is performed at the 2nd clamp circuit 53 after the signals are converted into inverted input picture signals by means of an inversional amplifier circuit 52. The picture signals thus obtained are inputted to the base of a transistor Q1 coupled between a power source and earth through a resistance R. On the other hand, the inverted picture signals are inputted to the base of another transistor Q2 connected in parallel with the transistor Q1. The circuit constituted in such way of the transistors Q1 and Q2 and resistance R is the comparator circuit to the picture and inverted picture signals and outputs OUT the signals in a low-level state out of the signals. Therefore, the level of the signals from the surrounding area of a person P becomes lower than that of the person P himself in the output OUT and picture signal in which the backlight state is eliminated are obtained.
