Automatic focusing system is provided which comprises a mirror or a plurality of mirrors with a translation device. Automatic focusing can be made by the translation of mirror because focal plane can be changed by the translation of mirror. The translation device makes its motion by the electrostatic, electromagnetic and/or electrothermal forces. The mirror is controlled by the electrical signal from the image processor to get an in-focus image. Also the mirror can be controlled discretely. The image shift by translation is compensated by tilt of mirror and/or image processing.
