Abstract
A color image pickup device has a solid-state image sensing element, a complementary color type mosaic filter, and a signal processing circuit which eliminates green highlights and provides accurate hue reproduction for all colors. Gamma compensation circuits process wide- and narrow-band luminance signals and two color signals derived from an output of the image sensing element. The gamma-compensated wide-band luminance signal is combined with a color subcarrier signal modulated by two color-difference signals formed from the gamma-compensated narrow-band luminance signal and the gamma-compensated color signals. The amplitude of the combined signal is limited by a white clip circuit. In one embodiment of the invention, the image sensing element is connected to the signal processing circuit by a cable of shielded lines. Waveform compensation circuits compensate in advance for deformation of the waveform of drive pulses for the image sensing element which occurs when the drive pulses are transmitted through the shielded lines. The external conductors of the shielded lines can be used to transmit power to the image sensing element.
