Abstract: A terminal device (300) includes a projection target holding unit that holds projection information to be projected by an image projection device (200), a storage unit that stores position information indicating a position on the retina of a user (P) at which the projection information is to be projected, a position information acquisition unit that acquires the position information from the storage unit, an image data generation unit that generates image data (D) of an image (202G) that projects the projection information at the position indicated by the position information, and an image output processing unit that outputs the image data (D) to the image projection device (200). The image projection device (200) includes a light source unit that emits a light beam, an image input unit that inputs the image data (D) from the terminal device (300), a control unit that generates an image light beam based on the input image data (D) and controls emission of the image light beam from the light source unit, a scanning mirror that scans the image light beam, and a projection unit that projects the image light beam on the retina of the eyeball of the user (P) as the image (202G) represented by the image data (D).
