Abstract
A method of superimposing and displaying a color image expressed by color code data and a color image expressed by three primary color dot data comprises the steps of converting the color code data into three primary color density data while converting the three primary color dot data into density data which are in the same form as the three primary color density data, and selectively displaying one of the two density data for each pixel on a display screen. Thus, two types of color image data, i.e., color code data and three primary color dot data are allowed to be handled in the same way and to be superimposed on a color display. This is useful in a color image filing system based on a workstation. In transferring the two types of color image data to a printer, the two image data are combined in memories and transferred to the printer as dot data through the existing printer interface. At the printer, the combined image data is divided into the previous two types of image data and printed in the same manner as in the display action.
