The Scanner Image Processing Research Based On ARM Processor

Color laser printer has become the main direction in the development of printer because of its high speed and strong color reproduction.The color image processing technology related to the color laser printer has been widely used in digital image processing.Compared with gray images,color images provide more information and can express more information.All kinds of office equipment multimedia output increased gradually and the media industry will continue to rise,increased demand for the output color printing,the color image quality requirements improve of the printed output speed requirements are also rising,so technical requirements and product quality of color scanning with market needs to improve.Color scanning,there are two key technology is essential,one is the ability to obtain the image of the scanning device,the other is to scan the image of digital image processing technology.Equipment accuracy is mainly determined by the social development of the manufacturing process and the development of semiconductor materials,in the short term to enhance the space is limited.Digital image processing technology,as a kind of popular technology in recent years,has a lot of research and promotion space.Based on high-end scanner color digital image processing research,found in existing scanner hardware invariant based on can be by improving the existing control process control method to improve the quality of the output image,verified by the actual output image analyzed.It is proved that this control improvement scheme on image quality does have to a certain extent,improve the.Is presented in this paper based on the hardware and software design of the special chip of image scanning,scan end image data processing,color space conversion and scaling function module of function structure,optimization design,the optimized design scheme of the image data of the test and to improve the image results are analysis and verification of the implementation analysis verified.The color space conversion and the scaling function module of the special chip are solved to solve the problem of the scanning data when processing the image of different specifications,and the quality of the output image of the product is improved.Through the experimental results,which can be confirmed,in this paper,we study method can be without changing the original function of the device and on the basis of improving the product cost,solve the actual product was obtained at the endof scanning image width does not meet the function of the chip can support problem of the width of the image,and makes the product have output image quality is improved.
