1. An optical module comprising:
a first display panel;
a first optical system that forms an exit pupil; and
a control unit that corrects an input image to a first image based on distortion generated in the first optical system, an aspect ratio of the input image being smaller than an aspect ratio of the first display panel, wherein
the control unit causes the first display panel to display the first image, and
the control corrects the input image such that a first length corresponding to a center of the first image in the first direction is different from a second length corresponding to an end of the first image in the first direction, the first direction along an input line on the first display panel.
