Display apparatus, display system, and mobile body

A display system comprising:

• an imaging apparatus configured to capture an image of a user;
• and
• a display apparatus that includes:
• a communication interface configured to receive position information regarding a position of an eye of the user captured by the imaging apparatus;
• a display element that includes a display surface having subpixels arranged in a grid pattern along a first direction and a second direction approximately orthogonal to the first direction;
• an optical element configured to define a beam direction of image light emitted from the subpixels in each of strip-shaped regions extending in the second direction on the display surface;
• a projection optical system configured to project the image light having the beam direction defined by the optical element to form a virtual image of the display surface;
• a driver configured to displace the optical element along a direction normal to the display surface;
• and
• a controller configured to displace the optical element using the driver.

A mobile body equipped with a display system, the display system comprising:
