Pictures are captured, and thereby moving-picture data is generated which represents a sequence of moving-picture fields. At least one picture is captured, and thereby still-picture data is generated which represents at least one still-picture frame corresponding in picture capture timing to one of the moving-picture fields represented by the moving-picture data. Components which correspond to said one of the moving-picture fields are removed from the still-picture data to generate supplementary still-picture information. Link information is generated which represents the picture capture timing correspondence between the still-picture frame and said one of the moving-picture fields. The moving-picture data, the supplementary still-picture information, and the link information are recorded on a recording medium.
