    摘要: An object region data describing method of describing information about the object region in an image over a plurality of frames determines the region of a target object in an image using an approximate function that approximates the trajectory obtained by arranging, in the direction of frame advance, one representative point of an approximate figure for the object region and the difference values for determining the other representative points and describes information about the object region using a parameter for the function.

    摘要: Since there is a case where reproduction of metadata is limited according to the processing power of a reproduction apparatus or the designation from a user, the invention provides a data structure in which metadata whose preferential reproduction is desired can be selected and reproduced. The metadata relevant to a moving image includes a stream data structure including one or more access units each being a data unit which can be independently processed, and each of the access units includes first data to specify an effective period defined with respect to a time axis of the moving image, object area data describing a spatio-temporal region in the moving image, second data including one of or both of data to specify a display method relevant to the spatio-temporal region and data to specify a processing to be performed when the spatio-temporal region is specified, and third data to specify, in a case where one or more access units exist on a same screen in the moving image at a time of reproduction of the metadata, reproduction priority of each of the access units.
