ABSTRACT:
Digital filter apparatus using a plurality of elements in common to process different signal components receives an image pickup signal from an image sensor and provides different image signal components from the image pickup signal. The digital low-pass filter includes delay circuits and taps for filtering a first image pickup signal component having a wide band in the horizontal, vertical, or time base direction. The delay circuits and taps also filter a second image pickup signal component having a narrow band in the horizontal, vertical, or time base direction. Thus, a plurality of digital filters having different functions may be realized utilizing common filter elements.
