Kind Code:
A1
Abstract:
The present invention provides a monitoring system that can reduce processing load on a monitor and that can reduce transmission data volume. A monitor 14 has a divided display mode for simultaneously displaying videos of a plurality of cameras by dividing a screen; and an enlarged display mode for displaying a video of one of the cameras on the whole screen. A camera 13 provided to each vehicle has: a memory 25 for storing information about a clipping range which is set for each of the cameras; a displaying video generation unit 22 for generating a full-size video or a partial video clipped from the full-size video on the basis of the information about the clipping range; and a displaying video transmission unit 26 for transmitting the full-size video or the partial video generated by the displaying video generation unit 22. In the divided display mode, the monitor 14 requests transmission of partial videos from the cameras 13 which are targets for displaying, whereas, in the enlarged display mode, the monitor 14 requests transmission of a full-size video from one of the cameras 13 which is a target for displaying.
