With the aging population, the demand for medical equipment will be increasingly valued. In view of this, the Yilingsi titanium series 16nm FPGA is adopted, connected to a 1mm 400 * 400 OV6946. After the full process ISP image enhancement is achieved on the FPGA, the image is then sent to RK3568 through MIPI CSI, further realizing system level applications such as OSD, encoding and decoding storage, Ethernet, USB, etc. Finally, the whole machine design is achieved, delivered to industry customers, and current image effects and delay problems are solved
