Abstract

Provided is a method for promoting the efficiency of scanning. When the scanner is scanning a region, the scanner system will check the region. If the color of the region has only one type at all, then the scanner system will omit the region and fill in some predetermined value to the memory which is related to the region by image process, and then scan other region continuously. The invention can increases the speed of scanning so as to reduce the scan time.

Description of the invention (l) The present invention relates to a manuscript area that is currently under scrutiny. 5 On the manuscripts currently known for tracing, (Charge-Cou comes to the scanner for its dpi scanning scan color and original color discrimination. Its scanning If you want to get it because of the degree of ambiguity, the resolution of the subsequent operation determines the resolution image of d ots-pe, and you need to scan the color information of the green and blue color information from the top. How to provide the scanning work is more rapid than described, but the image tracing speed is about a method to increase the scanning efficiency to scan the same color level to be scanned to speed up the scanning speed. The principle of the scanner's operation is to reflect the light first. After returning, please charge device, the CCD will convert the reflected light wave into the scanning software to read the data and emphasize the image recorded by the scanner (r-inch: dots per inch). The higher the image file, the higher the image file. It will take 5 long time, more memory and description, "Including-a kind of scanning color filter, light film for scanning," In other words, "through three times", because it takes three scans The color scanner's scanning method is fast, but the only drawback is that the resolution and the number of scans are, and the scanning speed is the current consumer when scanning at the South resolution due to the computer ’s own level, This method or swipe inserter is slower in nature. Known techniques will use this method, and especially when it is in the area, skip this. The digital data of the light irradiated by a so-called element) is grouped as computer influence. The larger the value of d p i is. The orientation method and the disk space method are successively performed, and the scanning process is separately performed so that when scanning, it only needs to scan it. The price affects the scanner speed, regardless of the design of the scanner driver. Go to the CCD light element to be scanned to control the scan file. The bit is the greater the resolution. Use red to get three complete color rooms and add one at a time, expensive. Degree of heavy emphasis in the software of the interface

In this method, when the scanner starts to scan the image, it will first perform a pre-scanning of the scanner (such as step 202). Then, it will calculate and collect from step 202 Scanning image related information (such as color type, scanning range, color distribution, image tilt angle, etc.). Then, image scanning will be performed (such as step 206). Next, an area to be scanned will be checked and judged Whether the area to be scanned belongs to the same color level (such as step 208). When the area to be scanned belongs to the same color level, skip the area to be scanned and fill it with an image concealment program (such as using a driver) The color level of the area to be scanned (for example, pure white is filled with 0 0H) (such as step 210), and then return to step 206 to continue scanning other areas to be scanned. If the scanning areas do not belong to the same color level, scanning is continued (such as step 2 1 2). After that, it is checked whether the image scanning is completed (such as step 2 1 4). When the result of the inspection is that the cat scanning is not completed, Return to step 206 and continue the image scanning. When the result of the inspection is that the scanning is completed, the image scanning is completed (such as step 2 16).
