A method and user interface is provided for use on a computer system coupled with a scanner for performing a scan operation on an original document, which allows the user to acquire scanned images in an easier and more user-friendly manner. The method allows the user to scan an original document without requiring the user to have learned knowledge background in the science of image processing, and also allows the scanner to perform only one scan operation on the original document. These features allow the use of the scanner to be easier and more user-friendly than the prior art. By the, method, the first step is to determine a set of image processing settings by a scanner driving program that are suited for optimal scan of the original document; and then the scanner is activated to perform a scan operation on the original document based on the image processing settings to thereby obtain a primitive scanned image. Next, an image-enhancement process is performed on the primitive scanned image to thereby obtain a quality-enhanced image; and finally, the quality-enhanced image is transferred to the application program for use by the application program.

A module of reflection mirrors of L-shape according to the invention, arranged in an optical chassis of scanner, is comprised of a first L-shaped mirror and a second L-shaped mirror. The recession portions for the second L-shaped mirror and the first L-shaped mirror are corresponded to each other in the space. After entering the module with a specific angle, an incident light is reflected several times between the two L-shape mirrors before it leaves the module with another angle again. Wherein, there are a first reflection zone and a second reflection zone at the recession portion of the first L-shaped mirror, and there are a third reflection zone and a fourth reflection zone at the recession portion of the second L-shaped mirror. After entering the module with a specific angle, the incident light passes through the second reflection zone, the third reflection zone, the fourth reflection zone, the second reflection zone, the first reflection zone, the fourth reflection zone, and the third reflection zone in sequence to get an appropriate optical length. Then, the reflection light leaves the module of reflection mirrors of L-shape with another angle that is different from the entering angle and is then focused into an image on a CCD by a lens.

A method and user interface is provided for use on a computer system coupled with a scanner for performing an automatic scan operation on an original document, with the computer system running a scanner driver and an application program. By the method and user interface, the scanner is first activated to perform a primitive scan operation on the original document based on the default image processing settings to thereby obtain a primitive scanned image. Next, the scanner driver is activated to perform a set of image processing routines on the primitive scanned image to thereby obtain the image qualities of the original document; and based on the image qualities of the original document, a set of suited image processing settings are specified for optimal scan of the original document. The suited image processing settings are then used to replace the default image processing settings, and the scanner is again activated to perform a final scan operation on the original document based on the suited image processing settings to thereby obtain a final scanned image which is transferred to the application program for use by the application program.

A paper-separating plate is adapted for a paper-separating mechanism having a paper-separating roller. The paper-separating plate placed around a side of the paper-separating roller comprises a main body and a cushion. The main body has a surface and a plurality of grooves and the grooves are positioned on the surface. The cushion is positioned on the surface of the main body and covers the grooves. The cushion positioned over the partial grooves is elastically pressed onto the paper-separating roller. The grooves are linear and the direction of extending the linear grooves is substantially parallel with the axis of the paper-separating roller, the linear grooves neighboring one another or each other. Besides, the cushion is made of flexible material and the main body is made of rigid material.

A method of increasing the scanning resolution of a scanner through controlling its driving system. By suitably adjusting the timing relationship between motor pulses and exposure pulses, a low-resolution driving system can produce a high-resolution image with no additional production cost incurred.

Increasing scanning resolution through driving system control

The present invention improves the contrast of the image signal before further adjustment by the principle of superposition of the optical-transferring system. There are two ways to carry out the principle of superposition one is in space domain, the other is in frequency domain. Each of them can be implemented by the system or method of the present invention. To implement the compensation in space domain, the present invention utilize the result of scanning the correction board to compensate the optical energy scattered by the optical-transferring system. A pixel in object space can be expressed in terms of the linear combination of the corresponding pixels in image space according to the principle of superposition. Thus is obtained by extracting the coefficients of the linear combination. The pixels of desired picture in image space is multiplied by the compensation vector and the image with sharp contrast is produced by the present invention in space domain. To implement the compensation in frequency domain, the present invention get the result of scanning the correction board and transform it to frequency form. Thus the compensation vector is obtained by extracting the amplitude and phase angle of the frequency form of the result of scanning the correction board. Transform the result of scanning the desired picture into frequency form, followed by dividing it by the compensation vector. The desired picture in frequency form is obtained. Taking the inverse transform of the desired picture, which is in frequency form, the result is transformed in space domain and can be processed or displayed with sharp contrast.

An improved apparatus for reducing memory usage of look-up table mapping in an imaging system, a method related to the apparatus is also disclosed. The apparatus receives a digital input signal and processes it through a two-step mapping procedures instead of conventional skill that it uses only one look-up table, each procedure provides a series of mapping outputs. A comparing unit composed of a lot of logical gates is then comparing those mappings with original input signal and choosing the best one for preparing a final output. Finally, a final output corresponding to the best choice is providing for displaying.
