Title: Luminance signal processing circuit for image-pickup device
Inventor: MIYAHARA HIROYUKI
IPC: H04N5/208
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To provide a luminance signal processing circuit for an image-pickup device that is capable of suppressing luminance flickers by adopting a configuration such that a frequency characteristic variable means which substantially varies the frequency characteristic of a filter circuit, in response to the state of a luminance signal. SOLUTION: When an image-pickup element output signal is saturated to cause luminance flicker, since a multiplication coefficient K is set zero by a control signal, an output luminance signal of a V-HPF 21 is cut off by a multiplier 23. On the other hand, a signal from a V-BPF 22 whose luminance flicker component by 500 TV lines is eliminated is fed to a horizontal low-frequency filter (H-LPF) 26 through a multiplier 24 and an adder 25. Thus, the luminance flicker is reduced.
