摘要: There is provided an illumination apparatus used for imaging a moving picture made up of plurality frames, and irradiating auxiliary light from source constituted by one or LEDs onto photo-object. The are duty-driven duty ratio smaller than 100% during period (during exposing CCD) frame period. heat releasing effect and-the emitting efficiency can be improved as compared to case where the successively turned on As result, intensity at time diodes heightened with amount consumed electricity unchanged, improved.
