Abstract: This display device comprises: a control unit which controls the display of an image on a dimming member that is provided so as to divide the projection surface of the image by a projector into a plurality of areas; and an acquisition unit which acquires a switching signal as an image display switching request. Further, the control unit specifies an area on which the image is to be projected, from among a plurality of areas, on the basis of the switching signal. Then, the control unit adjusts the light transmittance of the dimming member and processes the image to be projected on the projection surface such that the image is projected on the projection area specified by the switching signal.

Abstract: A touch type input device includes a display capable of showing a plurality of icons. A detector detects touching of an operation surface. A controller moves operational coordinates on the display based on the detection of the detector. The controller selects one of the icons in accordance with a region in which the operational coordinates are located. Further, the controller moves the operational coordinates to a specified position in the region where the operational coordinates are located when a touch-release operation is performed indicating that the touching of the operation surface has been cancelled.
