摘要：A method of superimposing and displaying a color image expressed by colorcode data and a color image expressed by three primary color dot data comprises thesteps of converting the color code data into three primary color density data whileconverting the three primary color dot data into density data which are in the same formas the three primary color density data, and selectively displaying one of the two densitydata for each pixel on a display screen. Thus, two types of color image data, i.e., colorcode data and three primary color dot data are allowed to be handled in the same wayand to be superimposed on a color display. This is useful in a color image filing systembased 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 datathrough the existing printer interface. At the printer, the combined image data is dividedinto the previous two types of image data and printed in the same manner as in thedisplay action.
