Image projection device, image projection system, and control method

摘要

An image projection device for projecting an image on a projection object includes a detecting unit configured to detect a detection object present within an object space corresponding to the image projected by the image projection device; a recognizing unit configured to recognize an instruction motion of a user based on detection of the detection object by the detecting unit; and an output unit configured to generate an output corresponding to the instruction motion recognized within the object space by the recognizing unit from the instruction motion and the image projected by the image projection device.

1. An image projection device for projecting an image on a projection object, the image projection device comprising:
a projection port from which projection light to project the image is emitted; an image sensor configured to capture an image of an object space corresponding to the projected image, the object space including an upper edge of a projection region that indicates a region on which the image is projected on a projection object, the image sensor being disposed in a position different from the projection port; and circuitry configured to
calculate a distance between the image projection device and the projection object using an amount of movement of the projection region in the image captured by the image sensor, the amount of movement changing depending on the distance between the image projection device and the projection objectcalculate a size of the projection region using the calculated distance;decide, as an instruction region in which an instruction motion of a user is performed, a region within the object space, using the calculated size of the projection region;detect a detection object present within the decided instruction regionrecognize the instruction motion of the user based on detection of the detection object; andgenerate an output corresponding to the instruction motion recognized within the object space from the instruction motion and the image projected by the image projection device.
