  • Patent number: 8948570
    Abstract: 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.

  • Publication number: 20140085464
    Abstract: An object of this invention is to simplify an operation of reproducing, on a single window, pieces of image information of different image capturing apparatuses or pieces of image information captured at different times. A display apparatus manages a camera apparatus (1) serving as the image capturing source of image information to be reproduced in each image region in association with a plurality of image regions on a single window. The display apparatus manages whether the image information to be reproduced in each image region is recorded image information or image information which is currently being captured. On the basis of the pieces of management information, the display apparatus acquires image information from a desired one of camera apparatuses and recording apparatuses and reproduces the pieces of acquired image information on the plurality of image regions.

  • Patent number: 8302142
    Abstract: When a request for a transmitting method of video frames of the client apparatus is received in a communicating unit to communicate with said client apparatus, whether the received request for the transmitting method of the video frames is a request for the transmitting method of the video frames for recording or a request for the transmitting method of the video frames for a live display is discriminated. If the received request for the transmitting method of the video frames is the request for the transmitting method of the video frames for recording, each of the video frames formed in an image sensing unit is temporarily stored in a memory and each of the stored video frames is transmitted. If the received request for the transmitting method of the video frames is the request for the transmitting method of the video frames for the live display, a process for transmitting the latest frame among the video frames formed in the image sensing unit is repetitively executed.

  • Patent number: 8279224
    Abstract: An object of the invention is to improve convenience in using a system capable of recording electronic data in association with time information. To achieve this object, an information processing apparatus of this invention includes a display control device which displays, on a display device together with a time line, time information which is obtained from a timer and associated with electronic data recorded by a recording control device, and a processing device which determines on the basis of the time information associated with the electronic data whether a count of the timer was corrected, wherein if it is determined that the count of the timer was corrected, the display control device displays, on the display device together with the time line, information representing correction contents of the time information.
