摘要： On a decoding side, parameters (minimum value MIN and dynamic range DR) are optimized in such a manner that a decoded error of original signal values and restored values becomes minimum. A maximum value detecting portion 2 detects the maximum value MAX of pixels of each block composed of (3.times.3) pixels. Likewise, a minimum value detecting portion 3 detects the minimum value MIN. A subtracting portion 4 generates a dynamic range DR. A subtracting portion 5 subtracts MIN from each of input pixel values y and generates normalized values. A step width calculating portion 6 calculates a quantizing step width .DELTA. with DR. A quantizing portion 7 generates quantized values x (each of which is composed of 4 bits) with .DELTA.. A least squares method based estimating portion 8 generates decoded values y' with y and x and obtains an optimized dynamic range DR' and an optimized minimum value MIN' in such a manner that the sum of square of an error (y'-y) becomes minimum. A framing portion 11 frames x, DR', and MIN' and records the framed data on a record medium 15 through an error-correction-code adding portion 12, a modulating portion 13, and a recording portion 14.

摘要： In the present invention, a virtual pixel (indicated by .circleincircle. in FIG. 18) is assumed near an SD pixel (indicated by .smallcircle.0 in FIG. 18) constituting an SD picture obtained by thinning an HD picture, and the pixel value of the virtual pixel is found from the HD picture. A part of the pixel value of the virtual pixel is arranged in place of a part of the pixel value of the SD pixel. Then, one of the SD pixels is used as a notable pixel so as to form a prediction tap from the SD pixel around the notable pixel and the virtual pixel. By linear combination between the prediction tap and a predetermined prediction coefficient, adaptive processing for finding a prediction value of the HD picture is carried out. In addition, a prediction error of the prediction value found by adaptive processing with respect to the HD picture is calculated, and the pixel value of the notable pixel is corrected in accordance with the prediction error. Thus, a decoded picture more proximate to an original picture may be obtained without deteriorating the coding efficiency.

摘要： Difference signals generated in the prediction encoding process for an input digital information signal are block segmented. The maximum value and minimum value of each block are detected. In addition, a quantizing step .DELTA. is calculated. An offset detecting circuit detects a zero position flag ZR and an offset off. The zero position flag ZR represents a quantized code that includes 0. The offset off represents the deviation between value 0 of difference signals and value 0 of restored representative values. A class category adaptive predicting circuit predicts ZR and .DELTA.. These values are not transmitted in other than exception process. With predicted values ZR and .DELTA., difference signals corrected with the offset off are quantized by a quantizing circuit.
