Abstract

PURPOSE:To enable to reject the television ghost with a simple circuit constitution, by the signal processing with the charge transfer internal the semiconductor without the voltage signal for the circuit between CCD and CCD delay circuit changed. CONSTITUTION:To one terminal of the input weighting circuit 221 of the input weighting type CCD transversal filter 220, the video signal including ghost is fed via the terminal 210. Further, the circuit reducing the simulated ghost from the video signal including ghost is constituted with the input weighting circuit 240, inversion amplifier 241, variable DC power supply 242, and analog delay part 261 of the filter 220, and the reduction is made by subtracting the output voltage of the power supply 242 with the output applying the voltage in which the charges in the circuit 221 are saturated and the polarity is inversed. Further, the number of transfer stages of the part 261 is taken longer than conventional ones, and the delay time between the output 243 of the circuit 240 and the output 250 of the CCD delay circuit 261 is made equal with time between the input and output of the CCd-DMLT 264 of the signal waveform corelativity unit 260. Thus, the video signal rejecting ghost can be obtained from the output terminal 250.
