To enable a presence/absence of a modification of a source video to be readily assessed in a derived video created by utilizing the source video. Relationship information including information indicating a segment corresponding relationship between at least one source video and a derived video created by utilizing at least a part of segments of the at least one source video and information indicating a presence/absence of a modification of the source video in a segment of the derived video in which the corresponding relationship exists is stored in a relationship information storing unit, and based on the relationship information stored in the relationship information storing unit, the segment corresponding relationship between the derived video and the at least one source video is displayed in a display mode in accordance with the presence/absence of a modification of the source video in the segment of the derived video in which the corresponding relationship exists.

Inter-video corresponding relationship display system and inter-video corresponding relationship display method

The present invention enables detection of a local differing region between images. Inter-image difference information indicating a difference in feature amounts for each subregion between first and second images is generated based on a first feature amount vector that is a set of feature amounts respectively corresponding to a plurality of subregions in the first image and a second feature amount vector that is a set of feature amounts respectively corresponding to a plurality of subregions in the second image, a differing region that is an image region that differs between the first and second images is detected based on differences in the respective subregions indicated by the inter-image difference information, and detection information that indicates a result of the detection is outputted.

Differing region detection system and differing region detection method

To enable a utilization frequency of each segment in a source video to be readily assessed between videos in a corresponding relationship during a creation process. Relationship information that is information indicating a segment in a corresponding relationship between a source video and a plurality of derived videos created using at least a part of segments of the source video is stored in a relationship information storing unit, and a corresponding relationship of the segment between the source video and the plurality of derived videos and a utilization frequency of each segment of the source video by the plurality of derived videos are displayed based on the relationship information stored in the relationship information storing unit.
