Abstract: A server enables a user at a station to scan a document. The station has a computer connected to the network, a browser installed on the computer to enable the user to browse the network, and a scanner in communication with the computer. The server has a database of scanner drivers, a driver selection system that enables the user to select a driver for the scanner from the database of scanner drivers, and a delivery system that transfers a selected driver to the computer and causes the computer to execute the driver. The user uses the browser and the driver selection system to select a driver for the scanner. The delivery system then sends the driver to the computer, and the computer executes the driver. The driver uses the scanner to scan a document, and scanning data corresponding to the document is saved in a predetermined location.

Abstract: The present invention discloses a halftone processing of image and text auto detection, which is used to keep both the bit depth of images and the clarity of text when faxing or copying documents. The process of the present invention is stated as follows: choose the background color from the master copy, separate the content of the master copy into images and text with the chosen background color as the criterion, process the images with halftone processing, process the text with line art processing, and then output the processed images and processed text as a whole.

Abstract: The present invention provides a method for dynamically refine the threshold values of R (Red), G (Green), B (Blue) colors for determining a borderline pixel in response to the values of a background image, thereby to precisely determine the borderlines of the Area of Interest (AOI). The method of the invention first searches the borderline pixels of a scanned image according to the standard differences of the R, G, B values of the pixels. Then, approximate the R, G, B threshold values of the borderline pixels by repeatedly averaging the current R, G, B values of the borderline pixels and the previous R, G, B threshold values until the difference is less than a predetermined value. The approximated R, G, B threshold values are set for the new R, G, B threshold values for determining the attribute of a pixel for subsequent prescanned images. Accordingly, the AOI can be automatically selected by reading the image circumscribed by the borderline pixels.

Abstract: The present invention relates to an apparatus having a light source for a transparent sheet of a scanner that includes a lamp, a reflective plate, a spreading plate and a protective plate. The light rays emitted by the lamp are used to scan a transparent sheet, the reflective plate in the arc shape reflects the light rays onto the scanning platform and there is an aperture on the predetermined position of the reflective plate to decrease the illumination for distributing uniformly the light rays. Besides, the spreading plate has a plurality of perforations to advance the light rays distributed uniformly. The protective plate made of the material pervious to light protects the components of this invention. As those described above, there are many advantages for the present invention, such as the structure is simple, the cost is low, and is much practical and can highly improve the performance of a scanner for a transparent sheet.

Abstract: The present invention relates to a curvilinear scanner including a main unit, a transmission mechanism, a curvilinear transmission shaft, a curviform document stand and an optical sensing module. During the scanning process, the optical sensing module conducts a curvilineal movement. Since the motion vector on the horizontal axis is shorter, it reduces the volume of the scanning device. By the curvilinear scanning way, it can scan an article with curve surface.

Abstract: An image reading device is activated by the light interference of a light path. The image reading device comprises at least an image sensing element, a picture and an image changing mechanism such as a picture conveying module, picture rotating module, a hole or a soft button with a picture in the inner side. The user may use a finger or other objects to interfere with the image generated in the image sensing element. By detecting the changes of the image, a predetermined activation process of the image reading device is therefore started.

Abstract: A double side scanner module which consists of a U-shaped inversion device and two image information reading devices is provided for reading images on the two sides of an original in a single pass. The U-shaped inversion device has two ends for providing a paper feeding path and a paper output path respectively. The two ends are at the same side for the convenience of operation. At both of the two ends, there is a glass window. Beneath each of the glass windows, there is an image information reading device. When an original is fed into the paper feeding end and conveyed through the first glass window, the first image information reading device starts to read the image on the first side of the original. When the original is conveyed through the U-shaped inversion device, the scanned side will be inverted to the other side.

Abstract: The present invention provides an image data processing system to increase the speed of on-screen display (OSD) image processing. The image data processing system comprises M color code registers for storing a plurality of color codes and a first multiplexer electrically connected to every output port of the M color code registers. The first multiplexer comprises a control port for inputting an N-bit image code, and the first multiplexer chooses one of the outputs of the M color code registers as its output according to the N-bit image code. The image data processing system comprises a processor for storing M color codes in the M color code registers and periodically transmitting a plurality of N-bit image codes to the control port of the first multiplexer so that the first multiplexer periodically chooses one of the color codes stored in the M color code registers as its output according to one of the N-bit image codes.

Abstract: A command conversion interface between an image machine with a plurality of hard keys and an image requestor is disclosed. When the command conversion interface detects and determines the activation of a specific hard key of the image machine, digital image information from the image machine is provided for the image requestor through the command conversion interface to execute a designated task, which has not been built in the image machine. In the command conversion interface, the designated task is interpreted by a destination command script, and the destination command script is processed by a compiler along with the digital image information, then transmitted to the image requestor to execute the task. The relationship between the specific hard key and the designated task refers to a new correlation table of the command conversion interface.

Abstract: An image scanner performing multiple scanning operations for a single scan line is disclosed. The additional scanning operations are performed between two adjacent pixels. For a double scanning mode, the CCD performs one scanning operation for a scan line at a first position. Then, the CCD is moved from the first position to a second position along the X-direction to perform the other scanning operation at the second position. The distance between the first and the second positions is a half of the distance between two adjacent pixels. The scanning data of the two scanning operations are alternatively arranged and converted into final image data. By this way, a low-pixel-density CCD can be used to obtain a high-pixel-density scanning quality.
