Abstract
A chapter information creation apparatus calculates, from field-of-view information, a position of a video image having a narrow field of view whose ratio to the size of a field of view of a video image having the widest field of view, among a plurality of hierarchically-encoded video images, is less than or equal to a threshold value. Chapter information is then created if a moved distance over a fixed period is greater than or equal to a threshold value. Chapter information is created for other video images if, based on a result of analyzing the video image having widest field of view, a change in that video image is detected. Chapter information for the video image of each layer included in video image data obtained by hierarchically encoding video images having different fields of view can thereby be created using a simple method.
