Patent number: 8427723Abstract: An image data sequencing method for a memory unit inside an optical scanning device. The image data sequencing method is particularly suitable for scanning a line of pixels with each pixel comprising a plurality of primary colors. The image data sequencing method involves scanning a line of pixels to obtain the data for a primary or secondary color. The pixels within the scan line are subdivided into groups. A storage space is reserved both before and after the address space inside the memory unit for holding the scanned primary or secondary color data so that all the primary or secondary color data constituting a pixel are in a fixed sequence next to each other inside the memory unit. When all the primary or secondary color data of pixels within a group are secured, the group of data is released from the memory unit.Type: GrantFiled: April 29, 2010Date of Patent: April 23, 2013Assignee: Transpacific Systems, LLCInventors: Tom-Chin Chang, Kuo-Jeng Wang

Patent number: 7912313Abstract: A shading correction is employed for a scanner to correct shading distortion. However, an image corrected with the shading corrective curve has shading noise lines due to the effects of various factors in the producing process of the shading corrective curve. The characteristic of the shading noise is that the each value of any primary color channel, of each pixel in a line is higher or lower than of the adjacent two pixels in other lines, wherein a color channel is one of red, green, or blue channel Hence, the quality of the image is improved by removing the shading noise detected from the characteristic described above.Type: GrantFiled: January 30, 2007Date of Patent: March 22, 2011Assignee: Transpacific Systems, LLCInventor: Kuo-Jeng Wang

Patent number: 7907310Abstract: An opening method for a double-sided scanner is provided. A light source of one particular color inside a first group of light sources and a light source of a different color (or the same color) inside a second group of light source are lit to scan the front and back surface of a scan document. Optical signals from the front and back surface of the scan document are received and converted into analogue electrical signals. Thereafter, the analogue electrical signals are converted into digital electrical signal. Finally, the digital electrical signals are output to a host computer. This invention utilizes two groups of light sources (for example, light-emitting diodes) to serve as light sources for the double-sided scanner. Because light-emitting diodes require no warm-up period and is quick to switch, double-sided scanning is simplified.Type: GrantFiled: May 6, 2008Date of Patent: March 15, 2011Inventor: Kuo-Jeng Wang
