Method and device for displaying video images

Abstract

Embodiments of the invention disclose a method and a device for displaying a video picture and relate to the communication technical field for reducing the jump feel and the hysteresis nature in a process for displaying the video picture. The method in the embodiments of the invention comprises the following steps of collecting a video picture at the current moment; carrying out human body detection on the video picture to obtain human body detection information; storing the human body detection information into an appointed storage space; determining a window whose continuous occurrence frequency within a certain time is greater than or equal to a frequency threshold in a character window as a first target window; determining motion parameters of the first target window according to the coordinates of the first target window in a certain time; determining a window with the stable motion condition in the first target window as a valid character window; and displaying the valid character window in the video picture. The method and the device are suitable for the process for displaying the video picture.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for displaying video images. Background technique [0002] With the development of communication technology, real-time transmission of video images can be realized through the network on the basis of video image processing, so as to achieve the effect of video conferencing. In the process of generating a video picture, the camera device can collect a frame of image at the current moment, and extract at least one focus point from the image to form a focus set; then divide the picture window to be output into several sub-pictures, and Filling the sub-image blocks corresponding to each focal point in the focus set into different sub-pictures respectively; after the filling process of the sub-image blocks is completed, output a multi-picture composed of several sub-pictures to realize the display of video pictures. [0003] When the characters di...
