Specifically, for image acquisition: The model of the image sensor selected in this system is AR0230CS. Its principle is that ambient light passes through the lens of the camera 21 and enters the optical channel of the device. The image sensor collects optical information at the end of the optical channel and realizes the conversion of optical and electrical signals through its internal CMOS. Further, the image sensor transmits to the video processing chip in the control module 10 in the form of SLVS differential signals or IMG single-ended serial signals. After color processing by the video processing chip, it is transmitted to the terminal display module 50 through a USB interface via the USB2.0 protocol under the JPEG compiler. For sound acquisition: After the microphone 22 collects the ambient sound, the signal is transmitted to the video processing chip in the control module 10 through the I2S protocol, and the video processing chip receives and processes it through the I2S D-MIC interface. Preferably, two D-MIC sensors are used in this system to collect ambient sound.
