An imaging unit is adjusted to come into focus on the projection screen. An image data extracting unit extracts image data in which a finger or the like exists and in which the finger or the like is brought into focus in image data obtained by the imaging unit. An operation determining unit determines content of operation performed with the finger or the like, on the basis of the image data extracted by the image data extracting unit. An input control unit recognizes content of an input instruction corresponding to the operation performed with the finger or the like, on the basis of data relating to the content of the operation performed with the finger or the like, position data of the finger or the like, and reference data for specifying a position and a size of the image projected on the projection screen, and controls a projection unit in accordance with the recognized content of the input instruction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image projection device","description":"An image projection device which can correctly discern content of touch operation when a user performs various kinds of touch operation on an image projected on a projection screen is provided.
