Abstract:
1. A storage device, comprising: a video input unit that inputs video data; an image thinning unit that generates low frame rate video data that has had a frame rate reduced by carrying out frame thinning on the video data; a video synthesis unit that synthesizes (i) the low frame rate video data generated by the image thinning unit and (ii) the video data in two screens to generate synthesized video data; and a storage unit that stores the synthesized video data which has been synthesized by the video synthesis unit, in a storage medium; wherein the video synthesis unit divides the video data into a plurality of intervals, and synthesizes the video data of each of the plurality of intervals and low frame rate video data associated therewith on a frame by frame basis; and wherein the image thinning unit generates low frame rate video data synchronous with the video data of each of the plurality of intervals, by using a respective leading frame of each one of the intervals as a leading frame of the low frame rate video data associated therewith.
