摘要： By changing coefficients of second-order and first-order calculation terms relating to respective hues, and first-order calculation terms in the form of comparison-result data relating to respective inter-hue areas, only the target hue or inter-hue area among the six hues of red, blue, green, yellow, cyan, and magenta, and the six inter-hue areas can be varied, without affecting other hues and inter-hue areas. Thus, the six hues and six inter-hue areas can be corrected independently, and the large-capacity memory is not required.

摘要： A digital video signal record and playback device for recording on a recording medium a digital video signal coded by using a motion compensation prediction and an orthogonal transform and playing back data from the recording medium. In a data arrangement of a digital video signal, an I picture which can be independently represented in a picture is divided into n areas in the vertical direction, and the data is arranged from the front of one GOP in the unit of area by giving a priority to an area located at the center of the screen. A playback picture is outputted by playing back the I picture read from the recording medium in the unit of area unit. In the case where the whole I picture area cannot be read within a definite time, the area which cannot be read are interpolated by the use of the data of the preceding screen.

摘要： An encoding system capable of preventing the overflow of a buffer and performing the encoding of a VOP within a predetermined time period even where the processing time period necessary for encoding each macroblock is not constant. In order to provide the encoding system, the maximum number of bits Tmax is set for each VOP, and the output of encoding unit and the output of fixed code output unit is switched and outputted so that the number of bits Sc of the VOP may not exceed the Tmax.

摘要： A coding apparatus, in which each block having a plurality of picture elements with digital image signals is divided into a plurality of sub-blocks, and an appropriate quantization step or weighting factor is decided on the basis of the absolute value sum of difference of image signal level between adjacent picture elements in the sub-block, so that a digital image signal is reduced. Moreover, a coding apparatus, in which each block having a plurality of picture elements with digital image signals is divided into a plurality of sub-blocks, and an appropriate quantization step or weighting factor is decided on the basis of the maximum and minimum values of the image signals of the picture elements in the sub-block, so that a digital image signal is reduced. Accordingly, in the coding apparatus as above, the state of the image is recognized for every block, whereby a block whose degradation of image quality is hard to notice at the decoder side is quantized or subjected to weighting with low rate, that is, with large reduction rate, whereas a block whose degradation of image quality is conspicuous at the decoder side is quantized or subjected to weighting with high rate, i.e., with small reduction rate. As a result, the image quality of the background having little change in the signal is kept good.
