Image processing systems and data input devices therefor
First Claim
1. An image processing system comprising:
- a data input device for generating input data;
an image processing device for performing a predetermined image processing operation on the data inputted by said data input device; and
a display device for displaying the result of the image processing operation performed by said image processing device;
wherein said data input device comprises a plurality of input instruments each including input means, and a structure to detect information on a position where said input means is manipulated to thereby increase a quantity of information to be detected,wherein said input means in each of said input instruments includes means for generating a frequency inherent thereto and means for changing said frequency depending on a writing pressure applied to said input means,wherein said means for changing frequency switches said frequency from one value to another at a predetermined point of said writing pressure,wherein said data input device comprises a panel responsive to a touch of said input means to said panel for detecting information on a position of the touch and for selecting color information corresponding to the frequency, andwherein said image processor performs an image process on the basis of the selected color information.

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.

8. An image processing system comprising:
-
a data input device which includes input means for inputting data to the system; an image processing device for performing a predetermined image processing operation on the data inputted by said data input device; and a display device for displaying the result of the image processing operation performed by said image processing device; wherein said data input device includes input means, wherein said input device further comprises a structure to detect information on a position where said input means is manipulated to thereby increase a quantity of information to be detected, wherein said data input device comprises a plurality of cards each used as an input medium for data with a code section at one end of that card on which information including at least a page of that card is stored, means for piling the cards the number of which is changeable, and detecting means disposed at a position deviating horizontally and upward from the card so as to face the code section on the card for detecting information on said code section in a non-contact manner, and wherein the code section contains a bar code which, in turn, contains information on the page concerned. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
