Scanning line interpolator using gamma correction memory |
摘要 |
A scanning line interpolator using a gamma correction memory includes a controller for outputting switching control signals according to an input video signal; an analog/digital converter for converting the input video signal into a digital signal; a first multiplexer for allowing the output signal of the analog/digital converter to pass according to the switching control signal output from the controller; a line buffer having a 1H delay for delaying the digital video signal having passed through the first multiplexer; a gamma correction memory for previously storing the scanning line interpolated digital video signal and then outputting it with the output signals of the analog/digital converter and 1H delay being taken as its addresses; and a second multiplexer for selectively outputting the output signals of the analog/digital converter and gamma correction memory according to the switching control signal output from the controller.
