Embodiment 2
[0123] The video automatic motion compensation method of the present embodiment includes:
[0124] S100. Obtain a video played by the video playback device;
[0125] S200. Detect the frame rate of the video, and if the frame rate is greater than a first set threshold, judge whether a scene change occurs based on the inter-frame correlation between two adjacent frames in each group of the video; The group consists of video frame images contained per second;
[0126] S400. If the frame rate is less than or equal to a first set threshold, do not perform motion compensation.
[0127] When the frame rate is less than or equal to the first set threshold, for example, less than 24 frames per second, since the interval between adjacent frames is relatively long, it is easy to interpolate frames and add video frames that did not appear in the original video This causes the screen to be broken, further aggravating the possibility of problems such as jitter and delay in the screen, and...

Abstract
The invention discloses a video automatic motion compensation method, device and equipment and a storage medium, wherein the video automatic motion compensation method is used for video playing equipment. The method comprises the following steps: acquiring a video played by the video playing equipment; detecting the frame rate of the video, and if the frame rate is greater than a first set threshold value, judging whether scene change occurs based on the inter-frame relevancy between two adjacent frames in each base group of the video, wherein the base group is composed of video frame images contained per second; and if the scene change occurs, obtaining the inter-frame movement speed between the adjacent frames in which the scene change occurs in the base group, and performing motion compensation on the video based on the inter-frame movement speed and the inter-frame correlation degree. The invention aims to solve the problem that an existing motion compensation method cannot be automatically adapted in some pictures, so that the user experience is influenced.
Description
technical field [0001] The invention relates to the field of video motion compensation, in particular to a video automatic motion compensation method, system, equipment and storage medium. Background technique [0002] With the development of the TV industry, the TV is becoming more and more intelligent and user-friendly, which is specifically reflected in, for example, more and more image modes of the TV. Nowadays, multiple image modes are often set in TV sets, including vivid, standard, sports, cinema, etc. Under these modes, some customized parameters will be designed correspondingly to meet user needs. For example: sharpness, contrast, color, noise reduction, motion compensation, etc. However, these adjustable parameters also have different levels. Such as: strong, medium, low and so on. Taking motion compensation as an example, motion compensation is to estimate the trajectory of the object's movement through chips and algorithms, and finally compensate for the pictu...
