Abstract

PURPOSE: To cancel the signal delay, by changing the timing of write-in and readout, in the time axis compression or extension circuit for the luminance or chromaticity signal.
CONSTITUTION: Luminance signal and chromaticity signal are respectively inputted to the terminals A and B. The output signal of the low pass filter 4 is delayed by tl. The start point of write-in to the time axis compression circuit 3 is delayed by tl and it is started by taking t1 + tl as reference. (where; t1 is the start of effective scanning period) The time of signal readout is started earlier by the delay time th with the low pass filter 4. The output signal of the filter 5 is shifted from the luminance signal A by one horizontal period. With this circuit, no delay line is required for the circuit through which the luminance signal passes.
