A video image encoding device, in a first mode, variable-length-encodes a residual coefficient to generate a coefficient code string, outputs the coefficient code string and the header information in a state in which the header information is associated with the coefficient code string, in a second mode, directly uses a differential image as a coefficient code string without variable-length-encoding the differential image, and outputs the coefficient code string and the header information in a state in which the header information is associated with the coefficient code string.

Device and method of video encoding with first and second encoding code

A video image decoding device receives, as the code string to be decoded, a first code string to be decoded including information based on an encoded residual coefficient and header information or a second code string to be decoded including a residual image obtained in encoding the code string to be decoded and header information. The video image decoding device, when the code string to be decoded that is received by the receiver is the first code string to be decoded, adds the residual decoded image and the predictive image to each other to generate and output a reconstructed image and, when the code string to be decoded received by the receiver is the second code string to be decoded, adds a residual image included in the second code string to be decoded and the predictive image to each other to generate and output a reconstructed image.

The image encoding apparatus which encodes, on a per block basis, a current picture included in a moving picture includes: an encoder which outputs a first encoded stream including, in the following arrangement order, (i) slice data obtained by encoding a slice included in the current picture and including a plurality of block lines and (ii) a slice header including information indicating a code amount of each of the plurality of block lines; and an exchanger which exchanges arrangement positions of the slice data and the slice header in the first encoded stream.

Moving picture encoding apparatus and moving picture encoding method

A moving picture encoding apparatus encodes a moving picture having an interlaced structure, and includes: a storage which stores fields as reference pictures; and an encoder which encodes a current field as a B-picture, using a first reference picture list which includes only one field in a same parity as the current field, and a second reference picture list which includes only one field in an opposite parity to the current field.

An image coding device which codes input image data includes a coding flag generation unit which determines whether or not the input image data is image data included in data of a moving picture showing a motion of a predetermined motion amount or greater, and generates coding flag information which indicates a result of the determination. A coding method determination unit determines a coding method in which the input image data references coded image data that the coded image data indicates is the input image data included in the data of the moving picture that is closer to the input image data. An image coding unit compression-codes the input image data using the coding method determined by the coding method determination unit.

A transcoder reduces the processing amount when a coded stream to which at least intra prediction is applied is transcoded into a coded stream to which intra prediction and inter prediction are applied. The transcoder converts a first coded stream to at least part of which intra prediction is applied, into a second coded stream to which intra prediction and inter prediction are applied. The transcoder includes a decoding unit that decodes the first coded stream to generate decoded image data; a prediction mode obtaining unit that obtains a prediction mode of intra prediction applied in decoding; and a coding unit that codes the decoded image data by applying the intra prediction or inter prediction to generate the second coded stream. A control unit controls causes the coding unit to use the prediction mode obtained by the prediction mode obtaining unit when the coding unit applies intra prediction.
