Abstract
In a monitor camera system comprising a monitor camera making 360-degree panning rotation and more-than 90-degree tilting rotation and a control unit for controlling the monitor camera, for masking a privacy zone in a picture taken by the monitor camera, the control unit sets mask data through the use of a contour parameter of a configuration of a mask zone for covering the privacy zone, while the monitor camera side holds the mask data to mask a portion of the picture with the mask zone defined on the basis of the mask data. According to this monitor camera system, since only a portion of the picture is masked with the mask zone, it is possible to protect the privacy from the picture taken by the monitor camera without impairing the monitoring function. In addition, since the monitor camera side holds the mask data, quick processing becomes feasible.
