In an electronic endoscope apparatus according to the present invention, a micromirror device reflects light from a light source to allow it to enter a light guide. A light blocking period is set by driving the polarization angles of micromirrors of the micromirror device to a light guide non-incident angle thetas. This light blocking period is utilized to read signals for all pixels for one frame stored in a CCD by the same exposure. Thus, the light blocking period can be promptly set to obtain a stably bright motion picture not affected by any motions, or the like. Further, the quantity of light can be controlled by controlling the polarization angles in the micromirror device. Furthermore, desired white light is obtained.
