摘要: Techniques for intensity compensation in video processing are provided. In one configuration, a wireless communication device compliant with the VC1-SMPTE standard (e.g., cellular phone, etc.) comprises a processor that is configured to execute instructions operative to reconstruct reference frames from a received video bitstream. A non-intensity-compensated copy of a reference frame of the bitstream is stored in a memory of the device and used for defining the displayable images and for on-the-fly generation of a stream of intensity-compensated pixels to perform motion compensation calculations for frames of the video bitstream.

摘要: This disclosure describes a scaler architecture for image and/or video processing. One aspect relates to an apparatus comprising an image processing unit, a memory, and a coder. The memory is configured to store processed image data from the image processing unit. The coder is configured to retrieve the stored, processed image data from the memory. The coder comprises a scaler configured to upscale the retrieved image data from the memory. The coder is configured to encode the scaled image data.

摘要: Motion estimation in video compressions systems. A programmable motion estimator may be used to estimate a motion vector for a macroblock in a current frame by searching for a matching macroblock in a previous frame. A controller may be used to program the motion estimator to perform a particular search.
