摘要： A method and apparatus of digital image decoding is provided for reducing compression-related deterioration of an image to a minimum with a reduced storage capacity. The digital image decoding apparatus is equipped with a compression rate judging section for judging an optimal rate of compression for effecting the least deterioration to the image based upon the size of image in connection with the storage capacity of a frame memory. A compressing section compresses decoded data based upon the optimal rate of compression and sends the compressed data to a predictive/display frame memory for storage. An expanding A section expands the compressed data based upon the optimal rate of compression and sends the expanded data to a decoding section when the expanded data is required. An expanding B section reads out the compressed data of a display frame from the predictive/display frame memory and expands the compressed data based upon the optimal rate of compression and sends the expanded data to a display unit for display.

摘要： A moving picture encoding system includes an encoding control unit for setting a target quantiser step size used to encode each of different types of pictures included in a unit group to be encoded, and for performing a control operation to generate and furnish a quantiser step size to an encoding unit so that a ratio among the target quantiser step sizes set for the different types of pictures is a predetermined one. The encoding control unit initially sets the quantiser step size for a macroblock to be encoded first in the current picture currently being encoded to the target quantiser step size set for the picture type of that picture, and, each time the encoding unit encodes each of macroblocks remaining in the current picture, then updates the quantiser step size initially set for the first macroblock so that the average of the quantiser step sizes used during the encoding of all macroblocks in the current picture finally approaches the target quantiser step size set for the picture type of the current picture. Thus the system is able to control the amount of codes generated during the encoding of each of the plurality of pictures in the unit group while keeping the relative picture quality among the plurality of pictures adjacent with respect to time.

摘要： An information source encoding system in which overload noise and block noise are less recognized and quantizing overload and large quantizing distortion can reduced within an intra-frame mode encoding region even when intra-frame and inter-frame mode encoding regions coexist in an image screen. An orthogonal converter outputs conversion coefficients in a predetermined spatial frequency region. A coefficient separating unit selectively separates the conversion coefficients. With the separated coefficient from the coefficient separating unit, a power is calculated. The calculated power is compared with a predetermined threshold value by a coefficient power determining unit. A step width controller sets a quantizing step width, based on the combination of a power determining ON/OFF signal the coefficient power determining unit and an adaptive control ON/OFF signal from the encoding controller, when the coefficient power is larger than the threshold value in the intra-frame mode, and sets a quantizing step width determined by the quantization characteristic designation signal from the encoding controller in remaining cases. As a result, a combined adaptive quantization characteristic signal having a quantizing step width for combined adaptive control is output to the quantizer.
