Abstract: A single step multi-section exposure scanning method for a scanner. The scanner includes a photo-sensor and a stepper motor. The photo-sensor has N rows of sensor cells that correspond to each primary color. The scanning device is driven forward an exposure distance for each revolution of the stepper motor. The single step multi-section exposure scanning method includes the following steps. First, the photo-sensor moves forward one exposure distance. One row of sensor cells is exposed after moving every 1/Nth of the exposure distance. Thereafter, analogue voltages obtained through the exposed row of sensor cells are transmitted to an analogue/digital converter. The above process is repeated until the entire document is scanned.

Abstract: A method of reducing memory requirement in the compensation memory unit of a scanner. The method includes providing an even compensation data value and an odd compensation data value and averaging the two to produce an odd-even compensation data value. Only half as much memory space is required to hold the averaged odd-even compensation data values.

Abstract: An optical scanner equipped with plug-in calibration film, which the optical scanner provides light incident upon a transmission-typed document and catches the image signals of the transmission-typed document by an optical chassis. The optical scanner equipped with plug-in calibration film includes a scanning zone and at least one attachment. The scanning zone is capable of providing for placing the transmission-typed document. The attachment is capable of providing a calibration film for enabling the optical chassis to retrieve the image signals so as to improve the image brightness.

Abstract: A method of optimal focusing for a document scanner is disclosed. The scanner includes an optical module movable in a given scanning direction to perform scanning operation over an area of a document in a scan line by scan line manner by being driven by an optical module moving mechanism under control of a control unit. The control unit includes a best focus value memory for storage of the best focus value for each scan line. The method includes the steps of moving the optical module to one of the scan lines of the document and retrieving the best focus value corresponding to the selected scan line. A focus adjusting mechanism is controlled by the control unit to move the optical module in a second direction to adjust the focus position of the optical module in accordance with the best focus value of the scan line. Once the optical module reaches the scan line, the operation of the optical module is temporarily suspended in order to have the vibration of the optical module damped out. Thereafter, a scanning operation is performed over the scan line.
