A head-up display includes a display device and an optical system. The display device includes a display panel, an input unit, a memory, and a controller. The display panel is configured to display an image. The input unit is configured to receive calibration information indicating a position of a calibration object and first position information indicating positions of user's eyes based on an image capturing device. The memory is configured to store the calibration information. The optical system is configured to allow a user to visually recognize a virtual image plane, which is a virtual image of the image displayed on the display panel, by reflecting image light emitted corresponding to the image toward the user's eyes. The controller is configured to convert the first position information into second position information indicating the positions of the eyes based on the virtual image plane by using the calibration information.
