Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] refer to figure 1 , the display format recognition method of the video file of the embodiment of the present invention, comprises the steps:

[0046] Step 101: divide the pixels of an image frame in the video file into an upper subsequence and a lower subsequence according to the horizontal axis, and divide them into a left subsequence and a right subsequence according to the vertical axis;

[0047] Step 102: calculating a first correlation coefficient between the upper subsequence and the lower subsequence and a second correlation coefficient between the left subsequence and the right subsequence;

[0048] In statistics, for sample sequences X, Y, the mathematical expression of covariance is:

[0049] cov(X,Y)=E[(X-E(X))(Y-E(Y))]

[0050]...

Abstract

The invention provides a display format identification method and device of a video file as well as a video player. The method comprises the following steps of: dividing pixel points of one image frame in a video file into an upper subsequence and a lower subsequence according to a horizontal axle line and a left subsequence and a right subsequence according to a vertical axle line; calculating a first correlation coefficient between the upper subsequence and the lower subsequence and a second correlation coefficient between the left subsequence and a right subsequence; and determining the display format of the video file according to the first correlation coefficient and the second correlation coefficient. By utilizing the method, the display format of the video file can be identified automatically, thereby bringing convenience for users.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a video file display format identification method, device and video player. Background technique [0002] Recently, stereoscopic display technology has been accepted by more and more viewers, and most video players support both stereoscopic video playback and normal 2D video playback. However, there is a common problem that the video player cannot recognize the display format of the video when loading the video file. This means that the viewer needs to use a common player to preview the video, and then the user determines how to play the video file, which brings inconvenience to the user. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a video file display format recognition method, device and video player, which can automatically recognize the video file display format, thereby facilitating the use of users...
