基于低功耗微控制器的图像采集系统设计

Design of the image acquisition system based on the low power microcontroller

为满足低成本低功耗发展需求,系统以TI公司推出的超低功耗混合信号微控制器MSP430为主控芯片,结合片内含有A/D转换功能图像传感器OV7670设计了一种低功耗微控制器图像采集系统。给出了系统的总体结构框图,采用图像传感器OV7670采集外部图像信息,并存储在先进先出存储器中,同时将图像数据通过微控制器传输到液晶屏进行显示。实验结果表明,本系统能成功实现图像信息的采集和输出显示,图像清楚,显示无失真。

In order to meet the needs of the development of the low power and the low cost.The system takes MCU MSP430 of the ultra-low power mixed signal microcontroller of the TI Incorporated as the core,with OV7670 Image Sensor that it have analog-to-digital converter to realize the low power MCU image acquisition system.The structure of the system is described.The OV7670 image sensor of the system gather image information of outside and store in the FIFO memory.Then MCU takes information to the TFT with display.Through the test and operation,the system realize that the image information of gathering and displaying.The displaying image is clear and not distortion.
