摘要

An image capturing system that records on a video recording unit a video captured by an image capturing apparatus and displays the video thus captured on a display unit comprises a change recording unit that records information of the time when, and the region where, a change of status occurs when the change detection unit detects such a change of status, and an extraction unit that extracts a partial region of video from the video thus recorded for displaying on the display unit. The extraction unit switches the video that is displayed on the display unit by extracting a video of the region of the change of status when the imaging time of the video that is displayed on the display unit reaches a time before a time prior to change that is preset, from the time when the change of status occurs.

1. A video displaying system adapted to display a video on a terminal device, the system comprising:
an acquiring unit configured to acquire a video of an extraction area based on a designation of the extraction area within a video frame by the user, wherein a plurality of video frames are recorded by a video recording unit as a recorded video; a first processing unit configured to perform a first control for displaying on the terminal device the video of the extraction area determined based on the designation by the user; a detection unit configured to detect an event within the recorded video; a determination unit configured to determine, in a case where a plurality of events are detected in a video frame of the recorded video, whether an area ratio of an event area including areas corresponding to the plurality of events and the areas corresponding to the plurality of events matches a predetermined ratio condition; and a second processing unit configured to perform a second control for switching of the video displayed on the terminal device from the video of the extraction area to (i) a video of the event area including the areas corresponding to the plurality of events in a case where the determination unit determines that the area ratio matches the predetermined ratio condition, and to (ii) videos of at least two event areas corresponding to the plurality of events in a case where the determination unit determines that the area ratio does not match the predetermined ratio condition, wherein the areas corresponding to the plurality of events are included within any of the at least two event areas, and wherein a position of the extraction area within the video frame based on the designation by the user is different from a position of the event area within a video frame of the recorded video, and wherein the extraction area and the event area are extracted from different frames of the recorded video recorded by the video recording unit.
