3D video field frequency conversion system and field frequency conversion method

Abstract

The invention relates to a 3D (Dimension) video field frequency conversion method. The method comprises the following steps of: A, separating left and right eye images according to a 3D image format input in a 3D video; B, respectively carrying out a scaling treatment on the separated left and right eye images; C, respectively carrying out a motion compensation treatment on the scaled left and right eye images; and D, outputting the motion compensation treated left and right eye images according to a specified field frequency. According to the method provided by the invention, the problem of no seeing a 3D effect due to image miscalculation caused by the traditional motion compensation algorithm is well solved; the problems of generating picture pause, serration and the like caused by simple frequency doublings are also well solved; a 3D video of a low field frequency also can normally be displayed on a display screen of a high field frequency; the 3D effect is not affected; a better image quality can be realized; and the problems of picture pause, serration and the like are not existed.

Description

technical field [0001] The invention belongs to the technical field of 3D television, and in particular relates to a 3D video field frequency conversion system and a field frequency conversion method. Background technique [0002] The principle of 3D imaging is to make the content seen by the left and right eyes different, so that the two eyes have parallax, and a three-dimensional illusion will be formed in the human brain due to parallax. like figure 1 As shown, the left-eye image and the right-eye image are respectively provided by the 3D device. The user's left eye sees the image corresponding to the left eye, and the right eye sees the image corresponding to the right eye. Stereoscopic image. [0003] Since the existing 3D signals are usually 24Hz and 30Hz field frequency signals, and the display on the LCD must be 50Hz, 60Hz, 100Hz, 120Hz, 200Hz, 240Hz or higher display field frequency, so the 3D equipment must have a low field frequency. Frequency multiplied to hig...

Problems solved by technology

[0004] In the traditional 2D motion compensation algorithm, because it does not distinguish between the left-eye image and the right-eye image, the correlation of several adjacent frames can be used to calculate a new frame, but since the 3D source is divided into left-eye images and the right eye image, so the traditional 2D motion compensation algorithm will cause the calculated image of the new frame to be wrong, so that the user cannot see the stereoscopic effect. If only through simple field frequency processing, although it will be seen To achieve a three-dimensional effect, but it will cause problems such as pauses and jaggies in the picture
