ABSTRACT:
A video signal processor which includes a circuit for converting the number of lines in a digitized video signal, a circuit for generating a display dot clock, a circuit for outputting analog pixel data subjected to a line number conversion and having a frequency different from that of the display dot clock, and a circuit for smoothing the analog pixel data; and in which a frequency fck of the display dot clock, an output frequency frk of the analog pixel data and a frequency fho of the horizontal synchronization signal satisfies an equation;
