Title: Flicker prevention device
Inventor: KAIZE KAZUHISA
IPC: H04N5/335
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of flickers in an image pickup output of a subject with a simple configuration where a fluorescent light driven by a 50 Hz commercial power supply is employed for the NTSC system image pickup device. SOLUTION: A period detection section 7 detects a period of a 50 Hz commercial power supply and a correction waveform generating section 8 generates a parabolic waveform for correcting brightness in synchronism with the detected period. An integration circuit 9 integrates the parabolic waveform in synchronism with a vertical scanning pulse of an image pickup element for a prescribed period, and the integrated output is latched by a latch circuit 10 in synchronism with a vertical scanning pulse. Since a gain of a variable gain circuit 3 is controlled in response to the latch output, flicker is eliminated.
