An endoscope apparatus includes a solid-state image pickup device, a video processor, a light source, a rotating shutter, a light transmission unit, and a display. The solid-state image pickup device for picking up an image of a body cavity is mounted at the distal end of an insertion portion inserted in the body cavity. A signal from the solid-state image pickup device is converted into a video signal by the video processor. An effective transmission interval of light from the light source for emitting continuous illumination light is controlled by a rotating shutter with a shutter blade rotated in synchronism with the video signal. Light transmitted through the rotating shutter is guided to the photographing portion for the solid-state image pickup portion. The video signal from the video processor is displayed at the display.
