VIRTUAL IMAGE DISPLAY DEVICE, CONTROL METHOD, PROGRAM, AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a virtual image display device that can suitably ensure visibility of a virtual image.SOLUTION: A head-up display 2 has a light source unit 4 and a combiner 9. The light source unit 4 has a control part 55 that acquires a front image Im obtained by photographing a front scene from a camera 3. The control part 55 predicts the apparent movement position of an object background Btag that is present in the front image Im. When the predicted apparent movement position of the object background Btag overlaps with the display position of a virtual image Iv, the control part 55 changes the display position of the virtual image Iv.
