A document camera has an automatic focus function, and performs the automatic focus process for automatically adjusting the focus lens to the focal position in accordance with the subject distance when the document camera is started up, or when the focus key of the input operation section is operated. Further, when performing the automatic focus process, the document camera is arranged to detect the focal position in the state in which the zoom lens is temporarily moved to the telephoto end with shallow depth of field, and then restore the position of the zoom lens to the original position.
