摘要： In order to produce a decoded image substantially identical to an original image by processing a small amount of data, utilizing a thinning circuit (subsampler) a level of compression data obtained by extracting 9 pixels of an original image by 1 pixel is limited by a level limiting circuit by extracting 2 bits thereof from an MSB. In a local decoder, the original image is predicted based on correction data to output a predicted values thereof. Then, in an error calculator, a prediction error of the predicted values with respect to the original image is calculated. The compression data is corrected by a correcting circuit in such a manner that this prediction error becomes small.

摘要： A memory efficient image processor receives DPCM prediction error values from decompressed MPEG coded digital video signals in the form of pixel blocks containing luminance and chrominance data in a 4:2:2 or 4:2:0 format and recompresses the pixel blocks to a predetermined resolution. Luminance and chrominance data are processed with different compression laws during recompression. Luminance data are recompressed to an average of six bits per pixel, and only a reference pixel and one other pixel are processed separately from all other luminance pixels in a block. Chrominance data are recompressed to an average of four bits per pixel. Each pixel block is stored with overhead information facilitating efficient and accurate reconstruction. Accurate pixel reconstruction is facilitated by processing a reference pixel accurately; scaling the pixel block; employing quantization tables which are symmetrical and fitted to the domain of the pixel block; biasing negative prediction error values to positive values; using short codewords in quantization tables at levels which are most likely to occur statistically; and processing each pixel with three, four or five bit quantization to ensure maximum resolution and an overall four-bit average for the pixel block.
摘要翻译：存储器高效图像处理器以4：2：2或4：2：0格式从包含亮度和色度数据的像素块的形式的解压缩MPEG编码数字视频信号接收DPCM预测误差值，并将像素块重新压缩到预定的解析度。亮度和色度数据在重新压缩时用不同的压缩规律进行处理。亮度数据被重新压缩为每像素平均6位，并且仅一个参考像素和另一个像素与块中的所有其它亮度像素分开处理。色度数据被重新压缩到平均每像素4位。每个像素块存储有开销信息，有助于高效和准确的重建。通过精确处理参考像素来促进准确的像素重建; 缩放像素块; 使用对称并适合于像素块的域的量化表; 将负预测误差值偏置为正值; 在量化表中使用最可能在统计学上发生的级别的短码字; 并且使用三个，四个或五个位量化来处理每个像素，以确保像素块的最大分辨率和总体四位平均值。

摘要： A block adaptive quantization device processes blocks of input data samples to determine an aggregate or average value which is applied to each of a number of exponent look-up tables to derive an exponent value dependent on the extent of compression required. The exponent value is split by an exponent splitter into a remainder value and a shift value. The remainder value is used to select one of a number of divide look-up tables to which the unsigned data sample is applied, and the shift value is used to apply a variable bit shift to the data sample. Each divide look-up table comprises the same group of divide look-up tables. The combination of the four look-up tables in the group, together with the variable bit shift defines a series of code tables made up of a group of divide look-up tables repeated at six dB intervals. The remainder value selects one of the code tables within the group, and the bit shift operation determines the selected one of the repeated groups. The code tables within the group are spaced logarithmically, as are the groups themselves. This arrangement considerably reduces the number of look-up tables required for a given processor, reducing the memory requirement and increasing speed.
