An image acquisition system is designed based on STM32F417. Taking STM32F417 microcontroller as the core, the system ac quires image information by CMOS image sensor OV7670. The image information through FIFO buffer is put into SD card under the con trol of microcontroller, then the information is previewed on LCD in real time. The system has reduced hardware resource, clear collect ed image and high expansibility. It is used in portable image acquisition system.
