PURPOSE: To provide a method and device for generating and displaying an icon on an image screen. CONSTITUTION: This is a device and method for displaying an icon on a screen. A random access memory 18 stores a series of line segments forming the icon. Each icon is formed as a linear combination of the icons from the plural segments. A processor 11 which executes an application calls the segments in accordance with a leading index number. The leading index number indicates the position in a display memory 13 for storing the leading segment. Each index number is incremented afterwards until all the segments of the icon are taken out of the memory and stored in the display memory 13.
