摘要： Disclosed are a device and a method for displaying a 3D image. A 3D image display device comprises: a stereo image analysis unit which receives a stereo image having a left image and a right image, and detects image information that contains edge information, color information, and/or scene change information; a first depth adjusting unit which determines a reference point by analyzing the distribution of depth of the stereo image based on the detected image information, and adjusts a three-dimensional effect of the stereo image by shifting the stereo image based on the determined reference point; a second depth adjusting unit which extracts depth map information in a pixel unit after reducing the size of the stereo image, and generates an image of a new viewpoint by warping the extracted depth map information such that the three-dimensional effect of the stereo image is adjusted; and a formatter which converts, according to a display device, the format of the stereo image having a three-dimensional effect adjusted by the first depth adjusting unit and/or the second depth adjusting unit.

摘要： Provided are a device and method for detecting watermarks in content carrying watermarks. One method for watermark detection according to the present invention comprises the steps of: extracting the label of a frequency component of the content; generating a bit sequence by making bit values correspond on the basis of changes in the label being extracted; checking correlation while shifting the phase of the band-spreading code (pn sequence) with respect to the generated bit sequence; and checking the amount of phase shift in the band-spreading code at times when the correlation checked in this way falls into the category of autocorrelation, and then determining a bit group having a value corresponding to the amount of phase shift checked in this manner. The bit group determined in this way constitutes part of watermark data.
