Abstract

The embodiment of the invention provides a screen display content superposition method and device, electronic equipment and a storage medium. The method comprises the steps of determining a characterdisplay area in a current frame image; creating a current OSD superimposed canvas with the same length as the character display area; obtaining a current OSD character string from a preset OSD character source; filling the current OSD superimposed canvas with the current OSD character string, wherein the OSD character string filled in the current OSD superimposed canvas deviates from the OSD character string filled in the previous OSD superimposed canvas by a preset number of characters; and superposing the current OSD superposition canvas filled with the character string to the character display area. Due to the fact that the OSD character string overlaid in the video frame deviates, when a video is played, an OSD seen by human eyes can present a rolling display effect, and therefore theoverall display effect of a video picture is improved.

Description

technical field [0001] The present invention relates to the technical field of computer applications, in particular to a screen display content superimposition method, device, electronic equipment and storage medium. Background technique [0002] Existing monitoring equipment, such as a DVR (Digital Video Recorder, hard disk video recorder), has a function of superimposing an OSD (On Screen Display, content displayed on the screen). Among them, OSD includes time, location, video channel number, and other information defined by the user. [0003] When the monitoring device superimposes the OSD, it directly superimposes the OSD on the original image of the video to realize the superimposed display of the OSD. However, the OSD superimposed by this method is always displayed statically during video playback, which makes the overall display effect of the image screen poor. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide...
