Description

TECHNICAL FIELD The disclosure relates to one or more embodiments of a control apparatus, an imaging system, a control method, and a program. BACKGROUND One of the conventional imaging systems (multi-light illumination apparatus control systems) uses multiple illumination apparatuses capable of wireless communication to provide illumination during imaging. Japanese Patent Application Laid-Open No. 2009-098296 discloses a method for quickly changing the settings of each illumination apparatus and confirming the effects. The plurality of illumination apparatuses in the multi-light illumination apparatus control system may include different types of illumination apparatuses, such as illumination apparatuses that provide illumination using flashlight and illumination apparatuses that provide illumination using steady light (continuous light). To provide proper illumination using multiple types of illumination apparatuses, light-emission settings may be properly set for each type (group) of illumination apparatus. However, the method disclosed in Japanese Patent Application Laid-Open No. 2009-098296 does not allow proper light-emission settings to be set for each type of illumination apparatus.
