Abstract
A projection device includes: a projection unit configured to project image light to a projection target; an image-capturing unit configured to capture an image of a range including the projection target to generate a captured image; a communication unit; and a control unit configured to transmit the captured image to an information processing device by the communication unit and cause a reception image received by the communication unit from the information processing device to be projected by the projection unit. The projection unit includes an image light forming unit configured to form image light and a projection optical system configured to project the image light formed by the image light forming unit toward the projection target. The image-capturing unit includes an imaging element configured to receive light through the projection optical system.
