Abstract: PROBLEM TO BE SOLVED: To provide a moving picture reversible compression method in the time-space region. SOLUTION: This moving picture reversible compression method applies three- dimensional space filling scanning to a moving picture consisting of three-dimensional time-space information being a temporal change of two-dimensional information and consecutively picked up to sequentially convert the three-dimensional time-space information into one-dimensional sequence information, and applies a reversible compression method to the converted information to compress data. The moving picture reversible compression method adopts three-dimensional prediction coding for the reversible compression method. The three-dimensional space filling scanning applies rectangular filling scanning extended in a time base direction so as to scan only once all grating points in the time-space region.  The three-dimensional prediction coding uses a prediction coefficient selection method that is used depending on a type of a context denoting locally different properties of the image having regions with a large change in the luminance value and with a small change in the luminance value in the time-space region. This method calculates the type of context of other colors by utilizing color information in a color space in the case of a color image so as to reduce the code quantity and the arithmetic quantity.
