Method for automatically detecting 3DTV video program format

Abstract

The invention discloses a method for automatically detecting a three-dimensional television (3DTV) video program format, which comprises the following steps of: 1, acquiring a frame image and judging whether the entropy of the frame image is greater than a first preset threshold value in the preset interval, if so, continuously executing, otherwise, returning; 2, equally dividing the frame image into n blocks; 3, respectively calculating linear correlation coefficients among the n blocks; 4, respectively judging whether a correlation coefficient of any two adjacent images in the n blocks is greater than a second preset threshold value, if so, adding one to a first counter, otherwise, adding one to a second counter; and 5, repeating 1 to (4m-1) times, if the first counter is m, the left and right three-dimensional format is obtained, if the second counter is m, the upper and lower three-dimensional format is obtained, otherwise, a two-dimensional format is obtained. In the method, whether the color is rich is judged according to the entropy of the image and the similarity between the images is judged according to the correlation coefficients between the image blocks, so the method is accurate and rapid.

Description

Technical field [0001] The present invention relates to the field of 3D digital television, in particular to a method for automatically detecting the format of a 3DTV video program. Background technique [0002] In the current broadcast television system or IPTV (Internet Protocol Television, interactive network television) and other systems, 3D digital television programs are broadcast. The main formats include left and right 3D video formats, up and down 3D video formats, etc. In addition, in the broadcast television system Or there are a lot of 2D programs in the IPTV system. [0003] With the continuous development of 3DTV (three Dimensional Television) technology, it is necessary to provide a method for automatically detecting whether the video program format is 2D or 3D. If it is a 3D video program format, it is necessary to detect which format the 3D video program belongs to 3D video program format, such as left and right 3D video format, top and bottom 3D video format.
