Abstract
An image processing system comprises means for detecting the position of an original, means for judging the tilt, the bending and the presence of the original and means for giving a warning or controlling any useless processing operation, thereby desirably editing and printing out the original without wasting copy papers, toner, time, power and the like.
Claims27
An image processing system for processing an image of an original document, said system comprising:
- means for detecting position coordinates of at least two corners of the original document relative to a coordinate system and for producing a detection signal representing the position coordinates;
- means for discriminating an angle of obliqueness relative to the coordinate system in accordance with the detection signal produced by said detecting means;
- means for inhibiting the image processing operation of said image processing system when the angle discriminated by said discriminating means is greater than a predetermined angle;
- and
- means for releasing an inhibition state of the image processing operation inhibited by said inhibiting means and for allowing the image processing operation even when the discriminated angle is greater than the predetermined angle.
An image processing system for processing an image of an original document, said system comprising:
- means for detecting position coordinates of plural corners of the original document relative to a coordinate system and for producing a detection signal representing the position coordinates;
- means for discriminating angles of plural edges of the original document relative to the coordinate system in accordance with the detection signal produced by said detecting means;
- means for recognizing when the original document is bent in accordance with the angles discriminated by said discriminating means;
- and
- means for controlling the image processing operation of said system in accordance with recognition by said recognizing means.
An image processing system as defined in claim 10, further comprising:
- means for displaying a warning in accordance with recognition by said recognizing means.
An image processing system for processing an image of an original document, said system comprising:
- means for reading the image of the original document to convert the image into an electric signal;
- means for discriminating an angle of obliqueness of the original document in accordance with the electric signal from said reading means;
- means for inhibiting the reading operation of said reading means when the angle discriminated by said discriminating means is greater than a predetermined angle;
- and
- means for releasing an inhibition state of the reading operation inhibited by said inhibiting means and for allowing the image reading operation even when the discriminated angle is greater than the predetermined angle.
An image processing system for processing an image of an original document, said system comprising:
- means for reading the image of the original document to convert the image into an electric signal;
- means for discriminating angles of plural edges of the original document in accordance with the electric signal from said reading means;
- means for recognizing when the original document is bent in accordance with the angles discriminating by said discriminating means;
- and
- means for controlling the reading operation of said reading means in accordance with recognition by said recognizing means.
An image processing system for processing an image of an original document, said system comprising:
- a platen on which the original document is placed;
- sensor means for receiving light from said platen to produce an electric signal corresponding to the light;
- means for discriminating an angle of obliqueness of the original document on said platen in accordance with the electric signal from said sensor means;
- means for inhibiting the image processing operation of said image processing system when the angle discriminated by said discriminating means is greater than a predetermined angle;
- and
- means for releasing an inhibition state of the image processing operation inhibited by said inhibiting means and for allowing the image processing operation even when the discriminated angle is greater than the predetermined angle.
An image processing system for processing an image of an original document, said system comprising:
- a platen on which the original document is placed;

- means for discriminating an angle of plural edges of the original document on said platen in accordance with the electric signal from said sensor means;
- means for recognizing when the original document is bent in accordance with the angles discriminated by said discriminating means;
- and
- means for controlling the image processing operation of said system in accordance with recognition by said recognizing means.
