Abstract: When a predetermined condition based on an instruction input from a user or a change in a posture of the user is satisfied (N in S300), an original image manipulating section of an image generating apparatus acquires amounts of displacement of viewpoints of a viewer from base points with respect to an image stereoscopically viewed by the user on the basis of display of left and right parallax images (S302). On the basis of the amounts of displacement, the original image manipulating section acquires the amount of adjustment of the position of an image plane in a virtual space in which the parallax images are expressed (S304). In generating, from each pixel on the image plane, an image reference vector for referencing the original images of the parallax images, the original image manipulating section executes calculation reflecting the amount of adjustment of the position of the image plane to achieve adjustment of the position of the image plane (S306).

Abstract: Without carrying out an analysis process of a photographic image, to identify a type of a subject which a terminal device has photographed. Based on data of a timetable format, a specified display device 40 displays the video of the subject of a specified type for a specified display time. A terminal device 10 specifies a photography location and a photography time by a camera 14. Based on the data of a timetable format, an assessment is made as to whether the photography location belongs to the same area as the display device 40 and whether the photography time matches the display time of the video of the specified type subject upon the display device. If it is assessed that said match is true, it is determined that the video of the specified type subject has been photographed by the terminal device.

Abstract: A surveillance apparatus continuously records imaged data from a camera into a circular buffer in a local memory. When a record signal is received, the system records the video stream that was recorded before the record signal was received, and the video stream that is recorded after the record signal was received. The recorded segment is then write-protected, so that the surveillance apparatus does not overwrite the recorded segment. The recorded segment could then be sent to a remote memory via a wireless connection to free up local memory for future recording sessions.
