Abstract
A display apparatus with detection function of the present disclosure includes a first illumination unit that outputs first illumination light, a light valve that generates image light by modulating the first illumination light on the basis of image data, a projection optical system that projects the image light onto a projection plane, a second illumination unit that outputs second illumination light used for position detection of a position detection object on the projection plane, a third illumination unit that outputs third illumination light used for image recognition of an image recognition object on the projection plane, an imaging unit where the second illumination light and the third illumination light enter through the projection optical system, and includes an imaging device disposed at an optically conjugate position with the light valve, and an image processing unit that performs position detection of the position detection object and image recognition of the image recognition object on the basis of a result of imaging by the imaging unit.
