The Research Of Image Record System Based On Portable Type

With the rapid development of computer technology and multimedia technology, especially the development of embedded Linux system, the reseach of portable type image record system is becoming a new light point of various applications. As embedded system, the image record system can meet the demand of many situations in power consumption, bulk and function. Based on the demand of special situation, to design on portable type image record system for special function has becommed a promising field.In this paper, we propose and design an image record system based on portable type. The system only retains essential information. It can have application in production and traffic field which always with no person. At first, the paper introduces the developing and application situation of embedded technology at home and abroad, and establishes the objective and content of reseach. And then we do many works in hardware component, integrated environment building, driver developing and video module designing based on the reseach objective. The works had contained the whole process of developing on embedded system.In the part of hardware component, we maily introduced the hardware module and the developing board, especially the processor of S3C2410. In the part of integrated environment building, we make elaborate on from the building of environment to the use of development tool. We design USB driver and camera driver in the part of driver developing part which place extra emphasis on introducing the driver development based on embedded Linux system. The part of video module designing is the core of the whole application program. In this part, we analyze and design in detail in the module of collecting, the module of loop and the module of compressing.At the end of the paper, the test scheme is introduced. We test the modules in the light of the scheme. The test indicated that the modules achieve the demand of design and realize the function of the image loop record. In addition, some functions modules which need consummating are presented, such as the file format, the USB driver and the way of compression, etc.
