摘要： An input digital video signal is encoded to produce at least first and second hierarchical data signals which respectively represent a first video signal and a lower resolution video signal. Each pixel data signal of the second hierarchical data signal is calculated as an average of N pixel data signals of the input digital video signal. The second hierarchical data signal is output together with first hierarchical pixel data signals representing only N−1 of the N pixel data signals of the input digital video signal. The first hierarchical pixel data signals may be differential signals produced by subtracting each of the N−1 pixel data signals from the average value of the N pixel data signals. During decoding the Nth pixel data signal is reconstructed from the N−1 pixel data signals and the average value provided as the corresponding second hierarchical pixel signal.

摘要： In a picture coding apparatus and a picture coding method, when a picture data is hierarchically coded, compression efficiency can be improved, and the deterioration of picture quality can be reduced. When a picture data is hierarchically coded by utilizing a recursive hierarchical representation, adaptive division of block is performed corresponding to the characteristic of the picture data and then coding is performed, and thus obtained hierarchical coded data is transmitted, so that the block of the lower hierarchy can be adaptively divided, thereby the information quantity such as a plane portion of picture can be reduced.

摘要： A subtraction device subtracts a predicted value generated by a predicting portion from a digital picture signal supplied through an input terminal. The subtraction device generates a difference signal as an output signal. A quantizing portion detects an activity of the difference signal, designates the number of quantizing steps corresponding to the activity, and quantizes the difference signal with the number of quantizing steps. The quantizing portion outputs side information to an output terminal.

摘要： An input digital information signal is prediction-encoded and thereby difference signals are generated. The difference signals are block segmented. A maximum value and a minimum value of each block are detected. Whether or not the range of levels of the maximum value MAX and the minimum value MIN crosses 0, a mode determining circuit 5 determines a quantizing mode and generates a mode signal MODE that represents the determined quantizing mode. When the range of the levels crosses 0, a first quantizing mode is selected. Otherwise, a second quantizing mode is selected. In the first quantizing mode, the quantizing circuit 6 performs the normal quantizing process. In the second quantizing mode, the quantizing circuit 6 performs a code conversion in such a manner that the number of bits of quantized output data is smaller than that of the normal quantizing process.

摘要： For each pixel in an operation block, an effective pixel determining unit sets a predetermined pixel difference (threshold value) on a time-base pixel difference. When the time-base pixel difference is less than the set predetermined pixel difference, it is determined that the pixel contributes to (or are effective in) motion vector detection, and uses the pixel in the gradient method in the case of performing motion vector detection. When the time-base pixel difference is not less than the set predetermined pixel difference, it is determined that the pixel is regarded as having a possibility to generate irregularity in movement, and the pixel is excluded from the gradient operation in the case of performing motion vector detection. The present invention is applicable to a signal processing apparatus for performing frame frequency conversion from a 24 P signal to a 60 P signal.

摘要： To compress images using transition information of adjacent pixels, index transition patterns of two adjacent pixels in the horizontal scanning direction of an image are computed and arranged in order of appearance frequency, then patterns within the upper four appearance frequencies are selected to create a reference table. Then, with reference to the created reference table, image data are encoded. When decoding the encoded data, at first data from both the reference table and the color look-up table is inputted and stored in the table 50 and the color look-up table 53. After this, the first data of the subsequent input data is supplied to both the color look-up table 53 and the delay circuit 51 by changing over the connection of the switch 52. Subsequent data is supplied to the table 50. The table 50 decodes the data to original image data with reference to the data and the output from the delay circuit 51. The color look-up table 53 then converts the decoded data to R, G, and B signals and output the signals.
