Title: LIGHT SOURCE CONTROL DEVICE, LIGHT SOURCE CONTROL METHOD, PROGRAM, AND SURGICAL SYSTEM
Abstract:
This disclosure pertains to a light source control device, a light source control method, a program, and a surgical system that allow observation in a more appropriate exposure state. A light source control device comprises a reflection direction estimation unit that estimates a reflection direction in which irradiated light is reflected by the surface of a subject to be photographed, and a control unit that controls, on the basis of the estimated reflection direction of the irradiated light, the orientation of a light source that emits the irradiation light. In addition, the control unit controls, on the basis of the reflection direction, so that illuminance as seen from the direction in which the subject to be photographed is observed is uniform or so that specular reflection in the direction in which the subject to be photographed is observed is suppressed. This technology can be applied to a surgical system used for endoscopic surgery, for example.
