Abstract

PURPOSE: To avoid the fear in illegible character and dirty screen, by moving the contrast volume so that no difference is made to the contrast and brightness between the picture and the character.
CONSTITUTION: The still picture signal is picked up from the reception signal, the picked up signal is stored in the memory circuit 31, and the still picture is obtained by sequentially reading out the stored signal. In this case, by turning the contrast volume 41 or luminance volume 42, the contrast or brightness of the picture and character is changed relatively, and no different is made between the contrast and brightness for picture and character to avoid the fear in illegible character and dirty screen.
