Abstract: A subject detecting unit 107 calculates a subject position on the basis of a subject region obtained by calculating the difference between an overhead image generated from an image for difference calculation stored in an image for difference calculation storage unit 106 and an overhead image generated by an overhead image generating unit 105. A projection plane calculating unit 108 forms a projection plane at the subject position, and a subject image generating unit 109 projects camera images of image taking devices 1a to 1c onto the projection plane, and generates a subject image. A display image generating unit 110 outputs to a display 2 an image formed by synthesizing the subject image with the overhead images generated by the overhead image generating unit 105.

Abstract: A reception unit of a video monitoring system receives imaged video from a plurality of monitor cameras, each of which images video of a corresponding region among imaging regions a to d in a certain place P. A control unit of the video monitoring system performs control to display the video received by the reception unit on a screen. An operation unit of the video monitoring system receives an operation for specifying the imaging regions b and d. When the video of the imaging regions a to d is displayed on the screen by the control unit, an instruction unit of the video monitoring system instructs the plurality of monitor cameras to transmit the imaged video in a first format. When the video of the imaging regions b and d is displayed on the screen by the control unit, the instruction unit instructs the monitor cameras which image the video of the imaging regions b and d to transmit the imaged video in a second format which has a larger data amount than the first format.

Abstract: A remote system fault detecting unit detects a fault in a remote system. A virtual resource management unit selects a virtual resource necessary for structuring a virtual system having the same system configuration as the remote system in which the fault has been detected, based on the remote system configuration information of the remote system. A virtual system structure unit structures a virtual system by using the selected virtual resource. A virtual system start unit starts the virtual system structured by the virtual system structure unit. When the fault in the remote system has been recovered, a virtual system stop unit stops the virtual system and the virtual resource management unit releases the virtual resource.
