摘要 |
The present invention is an analog screen-art circuit for displaying a video signal resembling a picture on a screen. The screen-art circuit includes a video signal processor having a color killer circuit for eliminating chrominance signals in a composite video signal. The screen-art circuit also includes an art mode selector for controlling the operation of the screen-art circuit, a number of serially connected delay elements for delaying the signal generated by the video signal processor by respective 1H periods and a switch for selectively switching the signals generated from the video signal processor and the 1H delays when operating in the art mode. The switch is responsive to a control signal provided by a control signal generator which logically combines a number of signals, one of which is based on a composite sync signal generated from the video processor. According to one embodiment of the invention, the other of the two signals is a head switching signal which is commonly found in most VCRs. According to a second embodiment, the other of the two signals is a vertical sync signal which is again extracted from the composite video signal. |
