  • Patent number: 9521392
    Abstract: A 3-dimensional (3D) video rendering device may convert a first left view video of a decompressed 3D video having a first frame rate to generate a second left view video having a second frame rate, and convert a first right view video having the first frame rate to generate a second right view video having the second frame rate. The second left view video having a particular pixel resolution may be converted by the 3D video rendering device to generate a third left view video having full pixel resolution of the decompressed 3D video. The second right view video having the particular pixel resolution may be converted to generate a third right view video having the full pixel resolution. The 3D video rendering device may generate a sequence of video frames for 3D video display based on the third left view video and the third right view video.

  • Patent number: 9318096
    Abstract: An audio processing device may estimate noise effects at a particular location based on noise measurement data corresponding to one or more noise sources. The audio processing device may modify one or more output audio content transmitted by the audio processing device to that particular location such that the modification may cancel the estimated noise effects at the particular location, at time when the output audio streams are received at that location. The noise effects estimation may also be based on audio reception measurement data at the particular location. The noise measurement data and/or the audio reception measurement data may be generated by audio capturing devices placed at or near noise sources, and/or at or near the particular location, respectively. The noise measurement data and/or the audio reception measurement data may be communicated to the audio processing device using wired and/or wireless connections.

  • Patent number: 9172954
    Abstract: A method for reducing memory bandwidth in a video decoder begins by performing a data reduction operation on a decoded first coded image to produce a second set of image data. The second set of image data stored and is selectively used for subsequent image decoding, thereby reducing the memory bandwidth. The data reduction operation can include image downsampling, wherein the pixel density is reduced by a factor of two in each of the vertical and horizontal directions.

  • Publication number: 20150078433
    Abstract: Bandwidth, power and/or storage may be saved when certain pictures of a video bitstream are selectively reduced in size prior to transmission and/or storage in a video decoding process. Any number of criteria may be used in determining which pictures are to be selected for reduction. For example, pictures that are to be used for display only and not to be used for future picture predictions or may be used only in a small number future picture predictions may be reduced.

  • Patent number: 8879834
    Abstract: A method and apparatus for reduced complexity video and image processing with special chroma handling are disclosed. Frame-type decisions are made on a video stream made up of a sequence of frames. A first subset of the frames are selected to be monochrome and generated without chroma data. A second subset of the frames are selected to be in color and generated with chroma components. In one embodiment, the first subset of frames includes odd frames and the second subset of frames includes even frames in the video stream. Under higher video frame rates, the lack of color in every other frame is not visible to the end viewer. Accordingly, subsequent processing of the output video stream permits luma-only processing of many frames in the video stream, extensively reducing the amount of computation.

  • Patent number: 8760574
    Abstract: An image processing method for frame rate conversion, comprising: receiving a stream of input pictures at an input frame rate, at least some of the input pictures being new pictures, the new pictures appearing within the stream of input pictures at an underlying new picture rate; generating interpolated pictures from certain ones of the input pictures; outputting a stream of output pictures at an output frame rate, the stream of output pictures including a blend of the new pictures and the interpolated pictures, the interpolated pictures appearing in the stream of output pictures at an average interpolated picture rate; and causing a variation in the average interpolated picture rate in response to detection of a variation in the underlying new picture rate.

  • Publication number: 20140125642
    Abstract: A device includes ocular image processing features. The device obtains ocular image data without requiring artificial lenses to capture the ocular image data. The device may, for example, obtain sensor data from a touch sensor associated with a display, recognize ocular image data within the sensor data, and process the ocular image data for any reason. This processing may occur regardless of the fact that the intended purpose of the sensor data was not for ocular imaging, but was intended for another purpose, such as detecting touch interactions with the display.

  • Patent number: 8610826
    Abstract: A video processing system may receive a current raw video frame and may estimate motion between the current frame and a previous frame to determine motion vectors (mv). Based on the same mvs, motion compensated (MC) noise reduction may be performed and MC frame rate conversion (FRC) may generate a new frame. The previous frame may be noise reduced and/or a raw video frame. A MC frame may be generated based on the previous video frame and the mvs. Noise reduction may comprise blending the current raw frame with the MC frame. A blending factor may be determined based on similarity between pixels of the current video frame and MC pixels of the previous frame. The mvs may be scaled for FRC. Noise reduction may be performed in parallel and/or prior to the FRC depending on whether raw or noise reduced frames are utilized.

  • Patent number: 8566382
    Abstract: Apparatus and methods for storing data in a block to provide improved accessibility of the stored data in two or more dimensions. The data is loaded into memory macros constituting a row of the block such that sequential values in the data are loaded into sequential memory macros. The data loaded in the row is circularly shifted a predetermined number of columns relative to the preceding row. The circularly shifted row of data is stored, and the process is repeated until a predetermined number of rows of data are stored. A two dimensional (2D) data block is thereby formed. Each memory macro is a predetermined number of bits wide and each column is one memory macro wide.

  • Patent number: 8126050
    Abstract: Methods and apparatus for implementing a reduced cost HDTV/SDTV video decoder are disclosed. The described joint video decoder is capable of decoding HDTV pictures at approximately the resolution of standard definition television pictures and can be used to decode HDTV and/or SDTV pictures. The described video decoder may be used as part of a picture-in-picture decoder circuit for providing picture-in-picture capability without providing multiple full resolution video decoders. The reduction in decoder circuit complexity is achieved through the use of a plurality of data reduction techniques including the use of a preparser, downsampling, and truncating pixel values.

  • Publication number: 20110051005
    Abstract: A video processing system may receive a current raw video frame and may estimate motion between the current frame and a previous frame to determine motion vectors (mv). Based on the same mvs, motion compensated (MC) noise reduction may be performed and MC frame rate conversion (FRC) may generate a new frame. The previous frame may be noise reduced and/or a raw video frame. A MC frame may be generated based on the previous video frame and the mvs. Noise reduction may comprise blending the current raw frame with the MC frame. A blending factor may be determined based on similarity between pixels of the current video frame and MC pixels of the previous frame. The mvs may be scaled for FRC. Noise reduction may be performed in parallel and/or prior to the FRC depending on whether raw or noise reduced frames are utilized.
