Abstract: One aspect determines centroids of a plenoptic image, which correspond to the center view of the plenoptic image. A search band spanning a range of different values along a search direction (e.g., range of ?y) is determined. Multiple slices of the plenoptic image are taken at different values of the search coordinate (i.e., different y values). Because the plenoptic image has a periodic structure imposed by the periodicity of the microlens array, each slice will have a strong frequency component at this fundamental frequency. A slice corresponding to the centroid location (i.e., value of y at the centroid) is selected based on analysis of these frequency components. In one approach, the slice with the weakest component at this fundamental frequency is selected as the centroid. A similar approach can be performed in the orthogonal direction to obtain the two-dimensional coordinates of the centroids.

Abstract: A display system includes a display screen, a plurality of subsystems, and a control system. The plurality of subsystems each generate an excitation beam that carries image information and a servo beam. For each subsystem, a servo feedback detector receives feedback light of the servo beam, detects the servo feedback mark, and produces a monitor signal.

Abstract: A smart multimedia content receiver automatically resizes video images based on the content being displayed on the TV screen. Such a self-formatting content receiver includes on-board image processing capability that provides continuous video analysis to detect changes in program formatting and convert each frame as it is received in real time, as opposed to processing and re-releasing an entire program or movie, or relying on the viewer to re-format programs manually. In response to detecting a change, aspect ratio adjustments are made as needed. Because the self-formatting content receiver has access to the video data before it is displayed, such automatic on-the-fly adjustments ensure that the viewer's experience during program changes is seamless and without distortion. Subscribers can influence decisions made by the content receiver by pre-setting viewer preferences for aspect ratio adjustment.

Abstract: Systems and methods for fixed delay video switching. One embodiment of the system describes a fixed delay video communication link, which includes: a real-time video encoder (RT-VE) that receives an incoming high-definition uncompressed video (HD-UV), compresses the incoming HD-UV into first or second HD compressed video, and transmits the HD compressed video over a communication link to a real-time video decoder (RT-VD). The RT-VD decompresses the HD compressed video into an outgoing HD-UV. And wherein on-the-fly switches between the first and second compression ratios, while continuing to receive the incoming HD-UV uninterruptedly, are both visually lossless and maintain the same fixed delay between corresponding pixels of the incoming HD-UV and the outgoing HD-UV.
