Abstract
An image processing system including a plurality of pen-like input units 31 which produce signals of frequencies inherent to the respective input units, a panel 32 responsive to a touch of the input unit 31 thereto for detecting its touch position and produced signal frequency, an image processor 5 which performs a predetermined image processing operation depending on signals indicative of the touch position and frequency from the panel 32, and a display 7 which displays the result of the image processing by the image processor 5. The respective frequencies determine corresponding color information used. The image processor 5 performs an image processing operation on the basis of the determined color information. Even when a card is used, page detection is performed in an optically non-contact manner, using a simple structure.
