Patent ID: 7505078

Claim:
A camera system including a stroboscopic device and camera, wherein said camera comprises information output unit which outputs, to said stroboscopic device, focal length information indicating a focal length of a photographing lens, and size information indicating a magnification with respect to a reference size of an exposure surface of an image sensing element, and said stroboscopic device comprises: an irradiation angle changing unit which changes any one of a plurality of irradiation angles of strobe light, the plurality of irradiation angles corresponding to a multiplication value of the focal length and the magnification; an information input unit which receives the focal length information and size information from said camera; and a control unit which sets the irradiation angle to a corresponding angle to the multiplication value when the multiplication value obtained based on the focal length information and the size information input from said information input unit is a corresponding multiplication value to any one of the plurality of irradiation angles and sets the irradiation angle to a corresponding angle which is the nearest to and smaller than a non-corresponding multiplication value among the corresponding multiplication values when the multiplication value obtained based on the focal length information and the size information input from said information input unit is not the corresponding multiplication value to any one of the plurality of irradiation angles.
