1. An image display system comprising:
a body in which a display displays an image thereon is provided, the body projecting a virtual image, corresponding to the image, onto a target space using outgoing light of the display, and the body installed in a moving vehicle body; and
an image forming unit that forms the image to be displayed on the display, wherein:
the image forming unit includes:
a processor; and
a memory including at least one set of instructions that causes the processor to perform operations when executed by the processor, the operations including:
correcting for distortion of the image; and
correcting a display location of the image on the display in accordance with an orientation signal representing a change in orientation of the moving vehicle body,
the image has a plurality of image regions,
the plurality of image regions include:
a first region to be subjected to the correcting the display location; and
a second region not to be subjected to correcting the display location;
the first region is an image region where a first corresponding image corresponding to a first virtual image is displayed, the first virtual image indicating which way to go at a nearest crossroad in front of the moving vehicle body,
when the moving vehicle body reaches a given distance from the nearest crossroad, the image forming unit forms the first corresponding image,
the correcting the display location is applied to the image that has been subjected to the correcting for distortion,
the correcting for distortion:
predicts a magnitude of correction to be made when the display location of the image is corrected,
reassigns, on the display screen, the distortion correction parameter to the divisional area shifted by the magnitude of correction predicted, and
applies the distortion correction to the image region of the image based on the distortion correction parameter reassigned, and
the predicted magnitude of the correction is nonlinear with respect to a variation in the orientation of the moving vehicle body.
