Video processing method, video processing device and video processing equipment

Abstract

An embodiment of the present invention provides a video processing method, comprising: acquiring video frames continuously input from a target video source; performing video processing on the received video frames using normal window parameters to obtain a display image and storing it in a first buffer; The display image in the first cache is for display; in response to the snapshot enabling instruction, and using the snapshot window parameter to replace the normal window parameter to perform video processing on the received video frame, to obtain the snapshot image and store it in the second cache; And after the obtained snapshot image is written into the second buffer, the video processing of the received video frame is automatically resumed using the normal window parameter. In addition, the embodiments of the present invention also provide a video processing apparatus and a video processing device that can perform the method. The advantages of the embodiments of the present invention are that not only the resource consumption can be greatly reduced on the hardware, but also the video source can be processed and then captured, and the operation is flexible and convenient.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video processing method, a video processing device and a video processing device. Background technique [0002] With the birth, growth and maturity of LED full-color displays, video processors have also emerged in the LED industry. The quality of the video processor directly affects the display effect of the LED display. A general video processor has functions such as color gamut space conversion, scaling, cropping, and enhancement. The processing method is, for example, selecting a certain video source for the host computer (normal window display input sources have different interfaces such as DVI, HDMI, DP, and SDI cameras, etc.) ) for processing, including processes such as color gamut conversion, scaling, cropping, and image enhancement. Next, the processed image is cached, and finally the window is output for display. [0003] In addition, the video proc...
