摘要： A method and system for automatic switching between three dimensional (3D) and two-dimensional (2D) contents on a 3D display system includes determining if a received video frame content is in a 3D format or 2D format. If the received video frame is in a 2D format, then the brightness of the received video frame is adjusted and the brightness adjusted video frame is converted into a 3D format for display. If the received video frame content is in 3D format, then the received video frame is displayed after converting the received 3D video frame to a 3D format compatible with the display.

摘要： Visual discomfort from depth jumps in 3D video content is reduced or avoided by detecting the occurrence of a depth jump and by changing the disparity of a group of received image frames including the frames at the depth jump in order to adjust the perceived depth in a smooth transition across the group of image frames from a first disparity value to a second disparity value. Depth jumps may be detected, for instance, when content is switched from one 3D shot to another 3D shot.

摘要： A method and system for adjustable 3-dimensional content are described in which a viewer can adjust the depth range according to the viewer's own visual comfort level and/or viewing preference. The depth change is achieved by shifting the left and right images of stereoscopic content image pairs so that corresponding pixels in the shifted left and right images of a stereoscopic pair exhibit a new horizontal disparity sufficient to achieve the desired depth change. By shifting the left and right images in an image pair, content objects in the scene can appear closer to, or farther away from the viewer than those same objects in the un-shifted image pair. This technique achieves a viewer controlled customization of the sensation of depth in the stereoscopic 3-dimensional content.

摘要： At least one implementation reduces chromatic aberration by aligning pixel in a color channel according to displacement from corresponding pixels in another color channel. In one particular implementation, a feature is calculated for a first block of pixels in a first color channel of an image. The feature is calculated for a second block of pixels in a second color channel of the image. Displacement is estimated between the first color channel and the second color channel by comparing the feature for the first block and the feature for the second block. At least a portion of the first color channel is aligned with at least a portion of the second color channel based on the estimated displacement.

摘要： A method identifies the presence of a three-dimensional (3D) image format in received image through the use of image difference determination. The received image is sampled using a candidate 3D format to generate two sub-images from the received image. When the candidate 3D format is a non-blended 3D format, these sub-images are compared to determine whether these sub-images are similar with respect to structure. If the sub-images are not similar, a new 3D format is selected and the method is repeated. If the sub-images are similar, an image difference is computed between the two sub-images to form an edge map. Thicknesses are computed for the edges in the edge map. The thickness and uniformity distribution of the edges are then used to determine whether the format is 2D or 3D and, if 3D, which of the 3D formats was used for the received image.

摘要： A method and system for calibration and compensation of color in a three dimensional display system includes user calibration of individual color channels using a multiplicity of grey screens while viewing with three dimensional glasses. Look-up tables are generated to ease conversion of input pixels to color corrected pixels to pre-distort the color of the pixels being driven by the three dimensional display system. Input pixels are then converted using the look-up tables and color corrected frames are displayed to a user. The pre-distortion effect allows a user to perceive colors in the three dimensional system as intended with the distortions caused by the viewing glasses and other aspects of the three dimensional display system.

摘要： At least one implementation determines whether two cameras are in parallel or are converging, based on an automated analysis of images from the cameras. One particular implementation determines the disparity of a foreground point and a background point. If the sign of the two disparities are the same, then the particular implementation decides that the cameras are in parallel. Otherwise, the particular implementation decides that the two cameras are converging. More generally, various implementations access a first image and a second image that form a stereo image pair. Multiple features are selected that exist in the first image and in the second image. An indicator of depth is determined for each of the multiple features. It is determined whether the first camera and the second camera were arranged in a parallel arrangement or a converging arrangement based on the values of the determined depth indicators.
