Abstract
PURPOSE: To increase the resolution of the TV video signals by defining the NH of even-number times as much as the H period of the original TV video signal as one horizontal display period and then applying the coding signals of one horizontal period obtained through sampling every NH/M to each picture element.
CONSTITUTION: Gated oscillator circuit f1 is triggered by the inverse output of preset pulse P1 to have oscillation with frequency f1. While gated oscillator circuit f2 is triggered by the output of NAND circuit N1 to have oscillation with frequency f2. And binary counter CT2 delivers the output to circuit N1 after counting the pulse of frequency f1 by the fixed times. Thus, the output corresponding to frequency f1 and f2 applied to AND circuit A1 and A2 via FF2 is obtained through the OR circuit. Here, the NH of even-number times as much as the H period of the original TV video signal is defined a one horizontal display period, and the coding signals of one horizontal period obtained through sampling every HN/M are applied to each picture element signl for display. Thus, the resolution of the TV video signals can be increased.
