Abstract:
A three-dimensional display device (3) comprises a display panel (7), a shutter panel (8), an acquisition unit (4), an input unit (5), and a controller (9). The display panel (7) includes a plurality of sub-pixels P for displaying a parallax image. The shutter panel (8) defines the beam direction of image light. The acquisition unit (4) acquires illuminance. The input unit (5) inputs the position of the pupil of an eye. The controller (9) causes a black image to be displayed by some of the plurality of sub-pixels on the basis of the illuminance. The controller (9) determines the origin position. The origin position EP10 is the pupil position where the center of a visible region (7a) in an eye-to-eye direction matches the center of a portion composed of contiguous sub-pixels P, among the plurality of sub-pixels, that display a first or a second image that corresponds to the visible region (7a). The controller (9) controls the display panel (7) on the basis of the displacement of the pupil in the eye-to-eye direction from the origin position.
