Abstract
An image processing apparatus for performing digital signal processing on an input color video signal is provided with a delay circuit for cancelling a time difference which occurs between a luminance signal component and a chrominance signal component of the input color video signal in accordance with a difference between a filtering processing for the luminance signal component and a filtering processing for the chrominance signal component.
Claims13
An image processing apparatus, comprising:
- (a) input means to which a luminance component signal and a chrominance component signal are supplied;
- (b) signal processing means for applying a predetermined signal processing to the chrominance component signal;
- (c) delay means for delaying the luminance component signal by at least a processing time which elapses during the predetermined signal processing in said signal processing means;
- (d) memory means for storing an output of said signal processing means and an output of said delay means;
- and
- (e) recording/reproducing means for recording the output signal from said memory means in a recording medium, and for reproducing the recorded output signal, wherein said memory means also stores the signal reproduced by said recording/producing means.

An image processing apparatus, comprising:
- (a) input means to which a luminance component signal and a chrominance component signal are supplied;
- (b) process means for processing the luminance component signal and the chrominance component signal differently, and correcting difference in time caused by the difference in processing;
- (c) memory means for memorizing an output of the process means;
- and
- (d) recording/reproducing means for recording the output signal from said memory means in a recording medium, and for reproducing the recorded output signal, wherein said memory means also stores the signal reproduced by said recording/reproducing means.
