Research and design of image acquisition system
摘要
Abstract
A digital image acquisition and processing system with 16 bit Freescale MCU MC9S12 XS128 as its main control chip was designed by means of the programmable characteristic of CMOS image sensor. In the system ,image collection is re⁃alized by camera OV7670,and the data buffer memory is achieved by FIFO frame memory AL422B to solve the problem of the speed desynchrony of MCU and OV7670. The two functions of camera shooting and picture taking were implemented successful⁃ly after hardware and software design. The obtained video and pictures are displayed on 3.5 inch TFT LCD in real time. The sys⁃tem structure is simple,and its universality is strong. The obtained video and pictures can expediently be transplanted to various type of processors. With some suitable application programs,the system can be applied to camera shooting,monitoring,security and protection,identification,etc.关键词
