    摘要: A method and apparatus for encoding and decoding an image. The encoding method includes: deciding whether pixel values of a first block of an image are identical to pixel values of a second block of the image that is encoded prior to the first block in a current slice of the image, and determining whether to encode the first block in a first mode according to the deciding; and selectively encoding the first block in the first mode based on the determining, wherein the first mode is a mode for encoding information representing that the first block is encoded in the first mode, instead of encoding the pixel values of the first block, when the first block is identical or similar to the second block.

    摘要: Output buffer slew rate variation over variations in load capacitance is minimized by dividing output voltage transitions into distinct time and output current segments. During the first time segment, the first drive stage with the smallest current is employed. After subsequent delays, additional drive stages are employed and the load current is sequentially increased. Each drive stage employs a specifically sized feedback device which, depending upon its dimensions will provide either parasitic capacitance to slow transitions or positive feedback to speed up transitions. The first stages are sized to incorporate parasitic capacitance, resulting in little change in the settling time of small capacitance loads over prior art output buffers. Latter stages use positive feedback to quicken the transition time which dramatically improves the settling time for larger load capacitances over prior art output buffers.
