摘要： An image coding apparatus includes a coding unit which generates coded data on a block basis, by coding the input image; a switching unit which selects and outputs either the coded data or uncompressed image data corresponding to the coded data; and a judging unit which judges, on a block basis, whether the code amount of the coded data is larger than a predetermined threshold. A control unit changes, to a predetermined specified coding type, the coding type of a first block and the coding type of a second block when the code amount of coded data generated by coding the first block is judged to be larger than the threshold, and the switching unit outputs the uncompressed image data corresponding to the coded data when the coding type of the coded data is the specified coding type.

摘要： A video coding device (100) includes a buffer simulation unit (103) that calculates an occupation amount of a virtual buffer to be used for controlling a coding amount, by using, for each picture, (a) a code length of a code that is an intermediate result of compression coding and (b) a code length of a compressed code that is a final result of the compression coding. This means that, for a picture that has not yet processed by an arithmetic coding unit (102), an occupation amount of the virtual buffer is calculated by using a code length of codes provided from a binarization unit (101).

摘要： A motion vector estimating device estimating a motion vector having high accuracy is provided. An eliminating unit eliminates each of pictures in a set of input pictures for each picture. A picture reducing unit reduces left pictures after the elimination, and generates reduced pictures. An overall motion vector estimating unit reads the reduced pictures, stored in the frame memory, as either reduced inputted pictures or reduced reference pictures, and estimates an overall motion vector between reduced pictures. Based on the overall motion vector estimated between the reduced pictures, a correction motion vector calculating unit calculates a motion vector between two reduced pictures as a correction motion vector. The correction motion vector calculating unit calculates the motion vector in the order of the inputted pictures in a pre-eliminated set of input pictures. A coding unit estimates the motion vector for each macroblock, using a determined search range, and performs cording processing.
