Image Acquisition Technology with AVR Single Chip Microcomputer

The image acquisition system is one of indispensable parts in various kinds of digital image application system. In this article, we developed a sort of video camera compact image acquisition and processing system based on AVR single chip microcomputer. The system utilises AVR single chip microcomputer ATmega16 with low power consumption and high performance as the data processing main control unit. Firstly, it completes the initialisation of CMOS light-receiving camera module C3088 through I²C interface. Then it is used to acquire image from C3088 and the acquisition states are displayed on LCD real time. Finally, the single chip microcomputer utilises serial communication interface to send data to the computer, which displays the image after data processing. The hardware circuit and the software programs of the system are designed.
