摘要： Methods and apparatuses for decoding a compressed video stream. In one aspect of the invention, a method to decode a variable length encoded bit stream includes: concurrently processing first data obtained from variable length decoding a first code word in a register while variable length decoding a second code word in the register. In one example, processing the first data includes: looking up an inverse zigzag index; computing an Inverse Direct Cosine Transformation (IDCT) coefficient; storing the IDCT coefficient in a buffer in a transposed inverse zigzag order; and branching conditionally based on a condition encountered in variable length decoding the first code word.

摘要： A temporal dithering manager uses temporal dithering to reduce contouring artifacts due to bit limiting. The temporal dithering manager truncates low order bits of an input signal, creates a temporal dither signal based on the truncated low order bits and applies the temporally created dither signal to the truncated signal. A temporal filtering manager applies a temporal filter to the truncated signal, thereby improving the quality of the truncated signal. The temporal dithering can be applied at a preprocessing stage, and the temporal filtering at a post-processing stage.

摘要： Systems and techniques for processing sequences of video images involve receiving, on a computer, data corresponding to a sequence of video images detected by an image sensor. The received data is processed using a graphics processor to adjust one or more visual characteristics of the video images corresponding to the received data. The received data can include video data defining pixel values and ancillary data relating to settings on the image sensor. The video data can be processed in accordance with ancillary data to adjust the visual characteristics, which can include filtering the images, blending images, and/or other processing operations.
