A display apparatus includes a display section that projects and displays an image on a display surface, an imaging section that captures an image of the display surface, a measurement section that measures the distance between the display surface and the display section, and a calibration processor that causes the display section to display a calibration image containing a position detection mark based on the distance measured by the measurement section, causes the imaging section to capture an image of the calibration image displayed on the display surface, and performs calibration that associates coordinates on the image with coordinates on the captured image captured by the imaging section based on the captured image.
