ABSTRACT:
A method of coding a moving picture in which the moving picture is input and coded to produce coded data comprises a picture capturing step for capturing a picture at time n..DELTA.t (n: integer .DELTA.t: time interval) of an input moving picture as a still picture and outputting still picture data; a time information producing step for outputting time information corresponding to time n..DELTA.t when the moving picture is captured as the still picture in the picture capturing step; and a coding step for sequentially capturing and coding the still picture data output in the picture capturing step, computing a time interval between two continuous still pictures in capturing time of the captured still picture data using the time information output in the time information producing step, and when the computed time interval is m..DELTA.t, (m: integer, m.gtoreq.2), inserting coded data corresponding to (m-1) or less still pictures between coded data and coded data of the two still pictures so that the time interval between coded still pictures is set to be constant.
