摘要： A novel video signal correction system is disclosed, in which an average picture level detection circuit detects the average picture level (APL) of a luminance signal, and a coefficient calculation circuit calculates the amount of correction by the APL circuit. An adder adds an APL-corrected signal to a corrected luminance signal. A limiter circuit, on the other hand, limits the lower limit level of an input luminance signal. A divider circuit divides an output signal of the adder by an output signal of the limiter circuit, and the result is used to correct an input color signal. The color signal is thus capable of being corrected in accordance with the APL while at the same time preventing excessive correction of the color signal with a low brightness input.

摘要： An I-axis phase pulse is allowed to be detected at the sampling point of a chrominance signal with a digitally-implemented circuit. A chrominance signal (sampling frequency f.sub.1) is subsampled by a frequency f.sub.2 (f.sub.1 /N) and subsampling pulses generated in N subsampling pulse generators 10 for N phases, the adjacent ones of the pulses being shifted by one clock (1/f.sub.1) with respect to one another. The subsampled chrominance signal is input to an I-axis determining circuit 17. The I-axis determining circuit operates to detect a maximum value M.sub.1 of a color burst signal (sampling frequency f.sub.1) and the data M.sub.2 after one clock and compare both of the values with each other. Based on the compared result, a selecting signal S.sub.4 is detected for selecting an I-axis phase pulse at the sampling point of the chrominance signal. A selecting circuit 18 selects, as an I-axis phase pulse S.sub.5, a proper one of the N sampling pulse for N phases based on the selecting signal and applies the I-axis phase pulse S.sub.5 to an (N+1)th subsampling circuit 19. The subsampling circuit 19 can provide an I-axis detected output S.sub.3 at the sampling point of the chrominance signal.
