Illumination Device, Imaging Device, and Imaging System
First Claim
1. An illumination device comprising:
- a light emitter that emits illumination light;
a modulating unit that causes the light emitter to emit the illumination light in a modulated state; and
a modulation controlling unit that controls the modulating unit to superpose on the illumination light a signal to be used in an imaging device that captures an image of an object illuminated with the illumination light.

Abstract
An illumination device performs illumination light communication, and signals indicative of the luminance of an object illuminated with illumination light and the color temperature of the illumination light are superposed on the illumination light. An electronic camera demodulates the illumination light received by a light-receiving circuit and determines the aperture value and the shutter value depending on luminance information included in the demodulation signal and an imaging sensitivity set in the electronic camera. The electronic camera demodulates the illumination light received by the light-receiving circuit and changes the color temperature adjustment reference used for color adjustment processing in accordance with color temperature information.
