Abstract
A surveillance camera apparatus includes a first storage unit for storing a size of pixels configuring a image-sensor, a computation unit for performing a computation using first information, second information, third information, and fourth information to calculate angle information on a plurality of vertex-points, the information stored in the first storage unit being defined as the first information, a focal length of an optical lens being defined as the second information, angle information on an optical axis that passes through a rotation center of the surveillance camera apparatus as the third information, and pixel information corresponding to a plurality of vertex-points that form a region to be masked whose image has been picked up by the image-sensor being defined as the fourth information, and a second storage unit for storing the computation result by the computation unit.
