ABSTRACT:
Disclosed are a method of displaying a color picture image and an apparatus therefor, in which there are provided a first memory into which a code of graphic display to be displayed on a picture screen is stored at a position corresponding to a display position of the code on the picture screen and from which the stored code is read out in synchronism with raster scanning on the picture screen; a second memory into which color display dot pattern data of N bits per color picture element on the picture screen are stored; and a circuit in which color display signals R, G and B are formed on the basis of output data produced from the first memory and transferred to a picture screen display means; in which reading-out control of the first and second memories in the case of color display is performed in the same manner as in the case of monochromatic display; in which the display color of each color picture element constituted by N bits on the picture screen is designated by N bits of the color display dot pattern data; and in which the color picture image is displayed by using the same memory capacity as that in the case of monochromatic display.
