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.

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: A system for real time image transmission and preview and a method thereof are applied on a scanner having a predetermined format therein, and an electrical device having a display module. The scanner scans a document in lines along a direction repeatedly according to the predetermined format. The scanner can promptly get an image and then wirelessly send the image out after each linearly scanning a part of the document. The electrical device wirelessly receives the predetermined format information and the image sent out by the scanner, and further edits a format of the image to fit in with the predetermined format so as to make the image capable of being displayed by the display module. Wherein the display module promptly displays the image thereon after each linearly scanning a part of the document along the direction and the image get thereby is received by the electrical device.

Abstract: The present invention provides a mouse with image system connecting to a computer. The mouse with image system provides a mouse mode for controlling cursor on a computer display and an imaging mode for taking images. The mouse with image system comprises a mouse body, mouse buttons disposed on an upper surface of the mouse body, a mouse displacement sensing system, an image system, a mode switch circuitry, a data transmission interface circuitry and a mode switch component disposed on peripheral side of the mouse body. The mode switch circuitry connects to the mouse displacement sensing circuitry, the image system, the data transmission interface circuitry and the mode switch component. At the moment of starting the computer, users operate the mode switch component to control the mode switch circuitry, so as to select firstly entering the imaging mode. Therefore, it is convenient for users to immediately and directly transmitting images without delay.
