摘要： A method for encoding a 10-bit based picture using a circuitry or devices inherently designed for handing an 8-bit based picture. The 10-bit based input picture data is motion-compensated with 8 bits in a motion compensation circuit. From the motion-compensated picture data, representative value data and the quantization width are found by an in-bloc representative value calculation circuit and a block quantization width calculation circuit, respectively. A difference between the picture data and the representative value data is found by an adder. The difference is sent to a block quantizer where first 8-bit quantized data is generated on the basis of the quantization width so that the representative value is at a mid point of the quantization width. The first quantized data is transformed by a discrete cosine transform circuit of a difference signal encoder to generate transform coefficients which are quantized by a quantizer to generate second quantized data. A variable length encoding circuit encodes the representative value data, quantization width and the second quantized data. The 10-bit based picture can be encoded by the circuitry or the devices designed for an 8-bit based picture without substantially deteriorating the picture quality.

摘要： The present invention is directed to an image information encoding apparatus, used in receiving compressed image information through network media when processing of such compressed image information is performed on storage media. A picture sorting buffer delivers information of picture type of frame Picture_type to a picture type discrimination unit. The picture type discrimination unit transmits command to a motion prediction/compensation unit on the basis of that information. The motion prediction/compensation unit generates predictive picture by using filter coefficients having the number of taps lesser than that of P picture with respect to B picture for which operation quantity and the number of memory accesses are required to more degree as compared to P picture on the basis of that command.

摘要： An encoding apparatus and an encoding method, a decoding apparatus and a decoding method, a recording medium, and a program suitable for encoding image signals with a higher compression ratio for transmission or accumulation. In an arithmetic coding section, from among the syntax elements of input image compression information, the frame/field flag is first encoded by a frame/field flag context model. When the macroblock to be processed is subjected to frame-based encoding, a frame-based context model, specified in the current H.26L standard, is applied. On the other hand, when the macroblock to be processed is subjected to field-based encoding, a field-based context model is applied for the syntax elements described below. The present invention is applied to an encoder for encoding image information and a decoder for decoding image information.

摘要： An image decoding method includes decoding encoded image data to generate a decoded image signal including a luma signal and a chroma signal. The method further includes scaling, when a reference field is a top field while a current field is a bottom field for motion estimation and when the decoded image signal is in a format in which the number of chroma pixels is vertically different from the number of luma pixels, a chroma motion vector of the chroma signal by mv/2+¼, where mv is a vertical component in a luma motion vector of the luma signal. The method also includes performing motion compensation of the decoded image signal using the scaled chroma motion vector.
