PROBLEM TO BE SOLVED: To allow brightness control with no requirement for moving a device for detecting brightness of a display screen such as a probe.;SOLUTION: In a brightness control system, an imaging device acquires an imaged picture by imaging a display screen of a display device. An angle acquisition part acquires, about a reference point on a vertical surface which is a leg of a vertical line that falls from a measurement point that is a point on the display screen down to a vertical surface relative to the display screen through the imaging device, at least any one of an angle formed between a segment that connects the imaging device to the measurement point and a segment that connects the imaging device to the reference point on the vertical surface, or an angle formed between a segment that connects the imaging device and the reference point on the vertical surface and a normal line of the display screen at the reference point on the vertical surface. A target brightness setting part sets a target brightness at the measurement point on the basis of the angle acquired by the angle acquisition part. A measurement brightness acquisition part acquires a measurement brightness at the measurement point based on the imaged picture. A brightness control part performs brightness control of a display screen on the basis of the target brightness and the measurement brightness.;COPYRIGHT: (C)2015,JPO&INPIT
