Claim 5:
6. A method of designing a head-up display, comprising:
determining a shortest distance at which a three-dimensional image is viewed;
determining a distance of a virtual image plane such that a convergence angle of a point on the virtual image plane onto which a virtual image of an image of a display panel is projected is less by 0.43 degrees than a convergence angle of a point positioned at the shortest distance;
determining a longest distance such that a convergence angle of a point positioned at the longest distance at which the three-dimensional image is viewed is less by 0.43 degrees than a convergence angle of a point on the virtual image plane; and
based on the distance of the virtual image plane, determining a configuration and arrangement of the display panel, an optical element that defines a propagation direction of image light emitted from the display panel, and an optical system that propagates the image light having a propagation direction defined by the optical element, toward eyes of a user, and projects the virtual image of the image onto the virtual image plane.
