PURPOSE: To improve readability by making the actual value of a blanking signal so as to depend upon both the color select bit of an actual pixel and color select bit of specific adjacent pixels. CONSTITUTION: A pixel generator 17 which generates color select bits is applied so as to generate both the color select bit of the actual pixel and the color select bit of the specific adjacent pixels corresponding to receiving an image line number L and a load signal LD1 on one side and another image line number L-1 and another load signal LD2 on the other side by turns. The image line number L-1 is obtained by applying the image line number L of a line counter 16 to an adder circuit 2. Further, an adder circuit 21 is a combination network which performs a modulo 10 addition of a value -1 to, for example, the received image line number L. Then the 1st and 2nd image line numbers L-1 are applied as select signals to a selector 22 which receives a column clock signal F1. Consequently, the readability is improved. |
