Patent JP-H01309591-A (JP)
Title: Solid-state image pickup device
Inventor: NISHIDA YASUAKI
IPC: H04N9/07
Filed: 1988-06-08
Abstract: PURPOSE:To obtain a video signal having less false signal by previously replacing the high frequency component of a primary color signal, for which a gamma correction is to be executed, with a synthesized signal in which the primary signal is mixed so that moire can be minimized. CONSTITUTION:Non-linear processing is executed for at least two signals out of third signals R2, G2 and B2 obtained by replacing signal components obtained by passing at least one signal out of at least two signals out of second signals Y1, R1-Y1, and B1-Y1 obtained by multiplying at least two signals out of first signals R1, G1 and B1 obtained from respective light receiving elements 11-13 by a first matrix coefficient through a first band limiting circuit 41 with other signal components obtained by passing the other second signal through a second band limiting circuit 42. Consequently, a moire signal is reduced before the signals are inputted to non-linear processing circuits such as gamma correcting circuits, and the possibility that the false signal occurs due to an intermodulation becomes smaller even when the sampling frequencies of the image pickup elements 11-13 are low. Thus, the video signal having the less false signal can be obtained even if the sampling frequency exists in a video signal band.
