Embodiment Construction

[0048] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0049] In the related art, in the process of adding a watermark to a video frame, an electronic device needs to apply for additional memory for each watermarked video frame to store the watermarked video frame. If the surveillance video includes many video frames, the electronic device needs to apply for memory frequently. Also, since the efficiency of reclaiming memory by electronic devices is generally lower than the efficiency of allocating memory, the problem of memory overflow (that is, insufficient memory) may occur in electronic devices during the process of adding watermarks.

[0050] An embodiment of the present application provides a video frame processing method, the method may be applied to an electronic device, and t...

Abstract

The invention discloses a video frame processing method and electronic equipment, and relates to the technical field of image processing. The electronic equipment can obtain the image data of the video frame from the memory, and can directly update the color value of each pixel of the sub-region where the watermark is located in the image data based on the determined target color so as to add the watermark to the video frame. In the watermark adding process, the electronic equipment can directly update the image data in the memory, so that the memory does not need to be additionally applied for the video frame added with the watermark, and the condition that the memory of the electronic equipment is insufficient can be effectively avoided.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a frame image processing method and electronic equipment. Background technique [0002] During the process of playing the surveillance video, the electronic device can add a watermark to each video frame included in the surveillance video. [0003] In related technologies, the electronic device may first acquire image data of a video frame to be played from a memory, and compress and encode the image data to obtain a video frame. Afterwards, the electronic device can draw a watermark on the video frame with the video frame as the background, so as to obtain a video frame with the watermark added. [0004] However, in the process of adding a watermark to each video frame, the electronic device needs to apply for additional memory for the video frame with the watermark added. If the surveillance video includes more video frames, the electronic device may have in...
