| Abstract: | 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. |
