In a configuration in which a visually recognizable display image is changed by changing viewpoint in a vertical direction, the present invention generates the display image in an appropriate mode. Disclosed is a head-up display comprising: an emission means for continuously emitting a first laser beam corresponding to a first image for a first viewpoint and a second laser beam corresponding to a second image that is for a second viewpoint and that is away in the vertical direction with respect to the first viewpoint; and a scanning means for scanning the first laser beam in a first scan pattern and scanning the second laser beam in a second scan pattern on a scan surface such that the display image relating to the first image when viewed from the first viewpoint becomes visually recognizable and the display image relating to the second image when viewed from the second viewpoint becomes visually recognizable. The first scan pattern includes a first straight line pattern where the first laser beam continuously enters, for each column, at least one column of optical elements linearly arranged in a first direction. The second scan pattern includes a second straight line pattern that is offset by a predetermined offset amount in a second direction with respect to the first straight line pattern.
