Abstract
A method and an apparatus for scanning an image. The method includes moving an image sensor; determining whether a side of a rectangular periphery is detected; detecting first and second reference points representing both end points of the side; receiving and scanning an image between the first and second reference points; deciding whether the side opposite to the side is detected; and stopping scanning the image, and stopping the image sensor.
Claims19
A method of scanning with an image processing apparatus which has an image sensor, and performs the scanning by reading an original document having a rectangular periphery line by line, the method comprising:
- moving the image sensor;
- determining whether a first side of the rectangular periphery is detected by the image sensor;
- detecting first and second reference points representing first and second end points of the first side;
- receiving and scanning an image between the first and second reference points;
- determining whether a second side of the document opposite to the first side is detected;
- and
- stopping the scanning when it is determined that the second side is detected, and stopping the image sensor.
An apparatus to scan an original document having a rectangular periphery line by line, the apparatus comprising:
- an image sensor receiving an image of the original document;
- a periphery detecting portion to detect a first side of the rectangular periphery or a second side opposite to the first side in response to the received image, and outputs the a result of the detection of the first side;
- a reference point detecting portion to detect first and second reference points corresponding to first and second end points of the first side according to the results of the detection of the first and second end points, and outputs the detected first and second reference points;
- an image scanning portion which scans and stops scanning the image between the detected first and second reference points;
- and
- an image sensor driving portion to move the image sensor in response to an image-scanning request signal, or to stop the image sensor in response to the results of the detection of the second side.
A method comprising:
- moving an image sensor a single time from a first side of a document to a second side of the document opposite the first side;
- detecting a size of the document during the moving;
- and
- scanning the document during the moving.
