Concerning the drawbacks of high cost and poor portability of traditional image acquisition and display scheme

an image acquisition and display system based on STM32 and OV7670 is designed.This system uses STM32F103ZET6 as core controller

use serial camera control bus（SCCB） to control OV7670 image sensor output RGB565

QVGA image data

at the same time

real-time display on TFT LCD is saved in SD card in BMP format.Experimental results show that the obtained image is clear and smooth

and the system has advantages of low cost

low power consumption and small volume

which can meet the needs of image processing and recognition.
