Claim:
A method for displaying a color image on a display device which has a plurality of pixels located in a matrix; and a switching element in each of the plurality of pixels, said method comprising: selecting a color by pointing a first position with a pointing device in a color selecting portion on the display device; detecting the first position on the display device by a detector; converting the color into color data by a color designator circuit; storing the color data in N storage regions of a memory device where each of the N storage regions has a number of addresses equal to a number of pixels in the matrix, so that 2 N colors are addressed for the display device; pointing a second position with the pointing device on the display device after selecting the color; detecting the second position on the display device by the detector outputting the position as an output signal having X-coordinate data and Y coordinate data; generating a first address from the X-coordinate data and Y-coordinate data; converting the color data into video data; and displaying the video data by an output circuit in accordance with the first address.
