Abstract: A device for calibrating scanned image includes a scanning unit arranged in a paper transmitting path for capturing texts and images on a document and transferring into electrical signals, a set of transmitting device which includes at least a first transmitting roller arranged upstream to the scanning unit, and a second transmitting roller arranged downstream to the scanning unit. There is no other transmitting roller arranged between the first and the second transmitting rollers, the distance between the first and the second transmitting rollers is shorter than the length of the document, and the second transmitting roller is faster than the first transmitting roller. A paper sensor is arranged in the paper transmitting path for detecting the position and the velocity of the document, and a control unit is connected with the paper sensor and the scanning unit to adjust the scan frequency in response to the position and the velocity of the document.

Abstract: An image correction device includes an input tray, a pickup roller, a separation roller, a plurality of first and second feed rollers, a scanning area, a sensor unit, a control unit, a plurality of paper-out rollers and a paper-out tray. The control unit electrically connects with the sensor unit and controls rotating speeds of the first and second feed rollers. An image correction method of image correction device is described hereinafter. When the paper is going to pass through the scanning area, the sensor unit sends a first signal to the control unit, when the sensor unit detects a transmitting status or a transmitting speed of the paper to be changed, the sensor unit sends a second signal to the control unit for modulating rotating speeds of the first and second feed rollers and the transmitting speed of the paper until the paper is scanned completely.
