<p>DIGITAL SCAN CONVERTER AND INCREASED RATE SYNC PULSE GENERATOR A digital scan converter includes an analog-to-digital converter or converting red, green and blue analog primary color signals to red, green and blue digital primary color signals, a memory for storing the red, green and blue digital primary color signals, a memory control circuit for writing the red, green and blue digital primary color signals in the memory at one speed and reading out the red, green and blue digital primary color signals from the memory at a faster speed, a digital-to-analog converter for converting the red, green and blue digital primary color signals read out from the memory to scanconverted red, green and blue analog primary color signals, a clock signal generator for supplying clock signals to the memory control circuit, the digital-to-analog converter and the analog-to-digital converter, and a synchronizing signal generator also controlled by the memory control circuit for producing synchronizing signals for the scan-converter red, green and blue analog primary color signals.</p> |
