Simple and convenient method for converting 2D (2 dimension) into 3D (3 dimension)

The invention relates to a method for generating the 3D (3 dimension) visual effect by using a 2D (2 dimension) movies, in particular to a simple and convenient method for converting 2D into 3D. The method is characterized by comprising the following steps that firstly, one frame of image to be displayed is stored in a memory, all odd columns of pixels in the image are read from the memory during output, and output at the display frequency at the time, a half of information of the frame of image is displayed on a display screen, then, the memory is read once again, the all rest even columns of pixels are read, the output is carried out in the same way at the display frequency, and at the time, the other half of information of the frame of image is displayed on the display screen, so the display screen alternately displays images formed by even columns of pixels and images formed by even columns of pixels. When the method provided by the invention is adopted, many-time tests show that through the practical sub
