Embodiment 1

[0020] Such as figure 2 As shown, firstly, the input 2D video signal is divided into left and right parts according to frames. Then add 5 columns of data to the data on the left of the frame according to the interval shown by the dotted line. The added 5 columns of data are generated by the difference method based on the left and right data. The data on the right of the frame is reduced by 5 columns of data corresponding to the data on the left according to the interval shown by the solid line. The frame processed by the above steps is used as the right eye data of the output 3D video. Output the input 2D video signal as left eye data to form a disparity map. Synthesize left and right eye views and output 3D signals. Then receive the signal of the next frame and repeat the same steps to complete the conversion from 2D to 3D.

Abstract

The invention relates to a method for converting 2D (two-dimensional) video signals to 3D (three-dimensional) video signals, which is characterized in that the method comprises the steps of (1) dividing input 2D video signals into a frame of picture according to a frame and cutting the frame of picture into two equal parts left and right in a vertical direction; (2) adding N data into data in the left part of the frame or reducing N data from the data in the left part of the frame according to intervals, wherein the N is more than or equal to 2 and is less than or equal to 20; (3) reducing N data from data in the right part of the frame or adding N data into the data in the right part of the frame according to intervals, in a way of corresponding to the treatment of the date in the left part, wherein the N is more than or equal to 2 and is less than or equal to 20; (4) employing the frames treated by the step 3 or the step 4 as left eye data or right eye data of output 3D videos; (5) outputting the input 2D video signals as right eye data or left eye data, so that the conversion from 2D video signals to 3D video signals can be realized; and (6) receiving the next frame of data and repeating the step 1 to step 5. The method provided by the invention takes the middle of an image as the center, and spreads / contracts towards two sides, so as to generate left / right eye view and then combine the left eye view and the right eyes view, so that a 3D effect is achieved.

Description

technical field [0001] The invention relates to a method for converting video signals from 2D to 3D. Background technique [0002] At present, due to the advantages of light weight, small size, low power consumption, low radiation, and good quality, flat panel display devices have been widely used in personal consumer products such as notebook computers, computer monitors, and televisions. [0003] With the continuous development of science and technology, 3D technology is becoming more and more mature and more and more accepted by the public. But at present, the main videos are basically traditional 2D videos, and 3D sources are only supported by a very small number of movies and clips. In order to allow the public to better experience the 3D effect, 2D to 3D technology is essential. Contents of the invention [0004] The purpose of the present invention is to provide a method for converting a video signal from 2D to 3D, which can obtain a good 2D to 3D effect. [0005...
