Design of Image Acquisition System Based on STM32

Abstract

In this paper, the STM32 chip with high performance, low cost and low power consumption is selected as the control unit. A highly efficient and portable image acquisition system is designed. The system uses OV7670 camera as the sensor to collect image signal, and the collected image signal is converted into digital signals and is stored temporarily in FIFO chips. Then the digital code which is stored in the FIFO chip is extracted by the STM32. The data will be displayed on the TFT-LCD color screen after processing. The image acquisition system can effectively collect the image signal, and display it.
