DISPLAY CONTROL DEVICE, HEAD-UP DISPLAY DEVICE, AND DISPLAY CONTROL METHOD

Positional correction of an image occurring along with detection of a shift in vertical eye position unintended by the user is suppressed. First image correction corrects the position of an image displayed on a display device based on a vertical eye position and a lateral eye position. Second image correction corrects the position of the image displayed on the display device based on the vertical eye position and the lateral eye position. A second correction amount to the position of the image with respect to the amount of change in the vertical eye position is smaller than a first correction amount to the position of the image with respect to the amount of change in the vertical eye position during the first image correction. A processor switches between the first image correction and the second image correction in accordance with whether a prescribed condition is satisfied.
