Abstract: With use of a simplified program or calculating device for motion compensation, a video decoding device decodes video data compressed by motion detection operations on macroblock units, as in the MPEG-4AVC standard. The video decoding device splits compressed data blocks of the prescribed size, 16×16 pixels for instance, to generate sub-blocks, which are smaller than the blocks and on which the video decoding device is able to execute motion compensation operations. The video decoding device duplicates a motion vector assigned to a given block to generate as many motion vectors as there are sub-blocks in the given block, and executes motion compensation on each sub-block using the corresponding duplicate motion vector. Data resulting from the motion compensation operation on each sub-block is combined to obtain a target block corresponding to the given block.

Abstract: Method and apparatus for dynamically changing streaming video quality are described herein. In one embodiment, a network traffic condition of a network and a local processing bandwidth of a client are periodically determined. A data compression method and/or compression rate is dynamically selected that is most appropriate to transmit a video frame to the client over the network in view of the determined network traffic condition and the local processing bandwidth of the client. The video frame is then compressed using the selected compression method and/or compression rate and sent over to a client to be rendered at the client.

Abstract: A process creates a depth map of a scene. The process is performed at a computing device having one or more processors, and memory storing one or more programs configured for execution by the one or more processors. For each of a plurality of distinct subsets of illuminators of a camera system, the process receives a captured image of a first scene taken by a 2-dimensional array of image sensors of the camera system while the respective subset of illuminators are emitting light and the illuminators not in the respective subset are not emitting light. The image sensors are partitioned into a plurality of pixels. For each pixel, the process uses the captured images to form a respective vector of light intensity at the pixel and estimates a depth in the first scene at the respective pixel by looking up the respective vector in a respective lookup table.

Abstract: An electronic device can have two or more pairs of cameras capable of performing three-dimensional imaging. In order to provide accurate disparity information, these cameras should be sufficiently rectified. Automatic rectification can be performed by periodically capturing images with the cameras of interest, and locating matching feature points in corresponding images captured by those cameras. Small misalignment errors can be treated as linear translations, such that a set of linear equations can be used to solve for the misalignments. Another process can process a set of homographies for the cameras until a cost function converges. Various other approaches can be used as well, such as to directly solve for yaw, pitch, and roll errors. Once this information is obtained, the misalignment values (or related values) can be stored for use in correcting images subsequently captured by those cameras.
