An optical input device has a display screen, a portion of the display screen being shielded from light by an operating member to implement input processing based on a plurality of input modes. The input device includes an input detection unit including a display unit that displays predetermined input information, and a control unit. The input detection unit detects an area and/or brightness of a light-shielded portion formed on the display screen by the operating member by approaching the display unit. The control unit provides display control of the display unit and input control on the basis of the detected area and/or brightness. The control unit compares the detected area and/or brightness with a predetermined threshold value to select a desired input mode from among the plurality of input modes.
