Abstract
A picture control system for a video cassette tape recorder, capable of compensating edge portions of a reproduction luminance signal by obtaining a hard compensating signal by filtering a high-band component of the reproduction luminance signal, a soft compensating signal by filtering a low-band component of the delayed reproduction luminance signal, and selecting the hard compensating signal combining control signal and then subtracting from the delayed reproduction luminance signal. The system includes a picture control signal generator, a hard-controller for filtering a high-band component of reproduction luminance signal, a soft controller for filtering a low-band component of reproduction luminance signal, and a signal combiner for selecting the hard and soft compensating signals and combining the selected signal with the delayed reproduction luminance signal.
