摘要： The present invention provides a calibration method and circuit for outputting an average calibration value used in an image-capture apparatus. The calibration circuit comprises difference means accepting a plurality of digital signals from capturing a pixel of a calibration chart. The difference means is for operating each digital signal with subtracting a base value, and whereby filters any aberrant digital signal. Divider means accepts the digital signals for operating each digital signal with dividing a number of scanned times, and whereby prevents an operation of any signal from overflowing. Direct average means accepts the digital signals for summing the digital signals and then divides the number of scanned times, and whereby speeds a calibration operation.

摘要： A method for differentiating dynamic range of image is disclosed. The method comprises the following steps. First of all, pixel numbers with the same level value of Density units D.sub.n−1 and D.sub.n are compared. Next the minimum pixel numbers of each level value of Density units D.sub.n−1 and D.sub.n are counted. Then the minimum pixel numbers of each level value of Density units D.sub.n−1 and D.sub.n are summed. Next the ratio of total minimum pixel number and total pixel number R and a specification value R.sub.s are compared. Then whether R is smaller than R.sub.s or not is determined so as to recognize whether Density units D.sub.n−1 and D.sub.n could be differentiated or not.

摘要： A chassis locking apparatus capable of being unlocked spontaneously is used for fixing the chassis in a scanner. The locking apparatus includes a groove interlinking next to the electric socket, a push rod in the groove, and a revolving locking element. By means of the strength of inserting the plug into the socket on the scanner, the push rod is pushed to move along the groove and hit the locking element, which is originally fixed on the chassis, to make the locking element rotate so that the chassis locking apparatus can be unlocked spontaneously. Therefore, no effort is necessary for a user to unlock the chassis locking apparatus by hand before using the scanner, which is convenient and timesaving.

摘要： Whenever a user prepares to use an application, or a file, to treat the scanned image of an object, the user only needs to place the object on a scanner and to select the icon of the application, or the file, and compile it with the icon of the scanner. The utilization of the present invention will automatically drive the driver of the scanner and integrate the relative information into the driver. Thus, after the scanned image is acquired, the application, or relative application of the file, is automatically active to treat the scanned image. Further, the format of the scanned image could be transformed by some applications such as the OCR.

摘要： A document holding fixture for a vertical optical scanner. The fixture has a main body, a transparent panel, four linking bars, a document cover panel, and a document backing plate. The document holding fixture uses a simple four linking bar system to maintain a constant parallelism between the document cover panel and the surface of the transparent panel. Weight of the document cover panel provides necessary pressure to press a scan document firmly onto the glass surface of the transparent panel. To facilitate single hand document insertion, a stationing device is used to freeze the document cover panel when the panel reaches a horizontal position.
