Research Of High Pixel Image Acquisition System Based On WinCE

The development of embedded devices has been with our life common progress. From intelligent mobile phone to the Internet of things, and intelligent Home Furnishing which will become a social concern in the next few years, all cannot do without the embedded equipment. Embedded device with image collecting function have been applied in manyimportant occasions in our life, and they occupy a certain percentage in many embedded devices. The resolution of the image is one of the important indicators to measure the level of an image acquisition system performance. High quality images in addition to be able to bring better ornamental effect, will also get better results in the latter part of image processing and image analysis. This is the meaning of this research.This topic chosen ARM microprocessor which is used as mainstream in embedded system and8000000pixel MIPI interface camera module as the system hardware. Camera module with MIPI interface has fast speed of transmission and can transmit a large amount of data. Compared with the traditional parallel interface camera module, it takes up less space and is more stable. The system software uses the Windows CE operating system, and the development of camera driver is in the system. Finally, using Windows applications on the CE system to open the camera and complete the image acquisition.This paper first introduces the development of embedded system and high pixel camera, described the future of embedded system device with image acquisition functions. Then it introduces the advantages of ARM series processor and MIPI interface camera module, designed the hardware circuit on the basis of this advantages, and focuses on the realization of the hardware circuit. Then analyzed the camera driver architecture, the characteristics of the Windows CE operating system and the main structure of its driver. And has a detailed description of the program design for the driver. Finally, is realization of the design in this paper and analysis of the results of system function test.
