The present invention provides a head-up display (HUD) device that alleviates a burden (including a psychological burden) that is imposed on a viewer in certain situations such as when the viewer is looking forward to see into the distance but the line of sight is obstructed by an image (virtual image) produced by the HUD device superimposed onto the front real view (foreground), consequently, the visibility of the foreground is reduced, visual attention is diverted to the image (virtual image) and visual attention on the foreground by the viewer is thus lowered, or the image (virtual image) feels annoying, for example. The HUD device includes an image display unit (140), an optical system (129, 133), and a control unit (120), wherein the control unit (120) sets a first display area (101) and a second display area (102) in a virtual display area (100) of a real segment in front of the viewer, and lowers the visual attraction of a display object (NV10 to NV30, CU1) displayed in the first display area (101).
