Abstract
The invention discloses a high definition video collection and display system, comprising a video collection module, a processor module and a display module. The processor module comprises a DM3730 processor, a power supply management module, a network module, a memory module, a TF storage card module, a USB module, an ISP interface module, and an HDMI interface module. The video collection module is used for collecting high definition video signals, and transmitting the video signals to the processor module with a high speed. The processor module is used for storing the video signals, utilizing the image processing capacity of the DM3730 processor to perform denoising, white balance and other front-end and back-end processing, and converting the video signals to a YUV format. The display module is used for outputting the video signals, and displaying high definition videos. The system can collect and display high definition images and videos, possess a storage function and facilitate video frame retrieval at any moment; in addition, the system employs a man-machine communication mode which facilitates supervision and control, reduces the pressure and labor cost of single manual supervision, and is more convenient and safer.
