VIDEO PROCESSING DEVICE AND VIDEO PROCESSING SYSTEM

A main video acquisition unit (21) acquires main video data including a video area of a shape having a curved portion from a main picture-capturing unit (10) installed at a predetermined position in a moving object. A sub-video acquisition unit (22) acquires sub-video data from sub-picture capturing units (11) to (14) installed at different positions in the moving object. A combiner (25) combines video data that is generated on the basis of the sub-video data and has a shape fitting to a free area other than the video area of each frame of the main video data, and arranges the video data in the free area. A file generator (27) generates one moving picture file based on the combined video data.
