Abstract

PURPOSE: To prevent the reduction in the vertical resolution by thinning out a horizontal scanning line placed for each horizontal scanning line of a video signal, applying arithmetic mean to a signal of the thinned horizontal scanning line and a signal of the succeeding horizontal scanning line and using the resulting signal for the succeeding horizontal scanning line.
CONSTITUTION: Since a signal on a scanning line LP 103 is displayed as it is on a color liquid crystal display device 9 but a pulse FP is unchanged for 2 horizontal periods, a signal of the succeeding scanning line LP 104 is not displayed but thinned. When a signal of a scanning line LP 105 just after the scanning line LP 104 is supplied, terminals 4c, 4b of a switch 4 are connected. In this case, a luminance signal Y0 being the result of arithmetic mean between a signal of the LP 105 and a signal of the LP 104 from a 1H delay circuit 5 is formed. The signal Y0 is fed to a color decoder 8 and fed to the device 9 together with a color signal C and displayed as the scanning line LT 4. Thus, a defect of a lateral grating picture in the scanning direction is prevented by the thinning processing and the arithmetic mean processing in this way.
