Abstract: Method for playing back three-dimensional (3D) images includes inputting an original video file; decoding the original video file for obtaining a plurality of images corresponding to a plurality of frames; dividing each of the plurality of images into a plurality of dissected images according to an input format of the original video file; and merging the dissected images into a playback file. When the original video file is played, the dissected images of the playback file are read and rendered for playing back a corresponding 3D image. When playing back the original video file, the hardware system only performs simple tasks such as reading and rendering the dissected images, and does not require performing complicated tasks such as decoding and dividing images, consequently reducing system resources consumed and increasing playback efficiency.

Abstract: The present invention utilizes determining the similarity between two adjacent frames to accelerate the computation of disparity maps of a stereo video. In a first stage, color similarity of pixels between the two adjacent frames is estimated. In a second stage, a plurality of feature points is selected from a previous frame, then the corresponding positions is located in a next frame for the feature points, and an average displacement of the feature points between the previous and the next frames is estimated. If the two adjacent frames are determined to be similar, the disparity map of the next frame can be obtained according to the disparity map of the previous frame. In such a manner, the computation of disparity maps of the stereo video can be accelerated.

Abstract: A dot matrix hologram with a hidden image is disclosed, wherein the hidden image technology is applied to a dot matrix hologram. Although the hidden image technology has been used in a conventional hologram, it has not been used in a dot matrix hologram. Although the above two kinds of hologram both can show hidden images with illuminating laser light, the disclosed dot matrix hologram with a hidden image and the conventional hologram with a hidden image use different working principles and have different detailed characteristics to create hidden image regions.

Abstract: A moire pattern technology about a dot matrix hologram for hiding a moire pattern is invented. In the moire pattern hidden region of a dot matrix hologram, the moire pattern foreground area and the moire pattern background area are formed identically by interlacing bright lines and dark lines. While position shifting is formed between the lines of the two areas. This position shifting is several times of the size of the grating dots. Thus, a moire pattern hidden in the moire pattern hidden region without being processed specially has a poor hiding ability. Often the above moire pattern can be identified by eyes directly without using a decoding film. Therefore, such kinds of moire patterns have poor hidden effects. However, the moire pattern of the present invention can prevent the aforesaid phenomenon by a well designed pretended pattern. Moreover, the appearance of such a dot matrix hologram can be beautified by the addition of the pretended patern.
