ABSTRACT:
A synchronizing frequency of red (R), green (G) and blue (B) video signals is detected by a frequency detector. The resolution of the RGB video signals is calculated by a calculator. When the resolution of the RGB video signals is close to the resolution of a cathode-ray-tube (CRT), a high level signal is generated as a control signal from a control signal generator. When the high level signal is generated from the generator, the video bandwidth of the RGB video signals is limited by a video bandwidth limiting circuit to adapt the RGB video signal to characteristics of the CRT.
