PROBLEM TO BE SOLVED: To provide the data input device and image processing system which cope with data input when a pen type or card type input means is operated, e.g. enables drawing on a drawing area of paper, etc., and supplies a signal corresponding to the kind of the input means to a processor. SOLUTION: The image processing system is equipped with the pen type input means 31, a panel 32 which assigns a specific frequency with the pen type input means 31 and detects the input position of the input means 31, an image processor 5 which performs a specific image process according to the signal from the input means 31, and a display 7 which displays the image process result of the image processor 5. Frequencies are assigned by colors, characteristic color information is determined according to a specific frequency, and the image processor 5 performs the image process with the determined color information. Even when a card is used, page detection can excellently be peformed by simple constitution without any optical contacting. |
