Abstract

There is provided a mechanism that enables a camera apparatus to record an appropriate video image relating to circumstances in which radiation imaging is performed in an imaging room. A radiation imaging system includes a radiation generating apparatus configured to generate radiation toward an object, a radiation detecting apparatus configured to detect, as an image signal, the radiation incident thereto, a camera apparatus configured to record a video image relating to circumstances in which radiation imaging is performed using the radiation in an imaging room, and a camera control apparatus configured to control the camera apparatus. The camera control apparatus recognizes an imaging location at which the radiation imaging is performed in the imaging room, and sets a parameter of the camera apparatus in accordance with the recognized imaging location.
