Display control device and non-transitory computer readable storage medium for display control by head-up display

A non-transitory computer readable medium storing a computer program product comprising instructions for controlling a superimposed display of a content by a head-up display for a vehicle, the instructions being configured to, when executed by one or more processors, to cause the one or more processors to:

• estimate a visible area that is a part of a road surface in a foreground included in an angle of view of the head-up display and is visible from an occupant, and an invisible area that is a part of the road surface in the foreground included in the angle of view of the head-up display and invisible from the occupant;
• distinguish, in a route content that presents a scheduled traveling route of the vehicle and is superimposedly displayed on the road surface, a visible part superimposed in the visible area, an invisible part superimposed in the invisible area, and an overlapping portion at which the visible part and the invisible part overlap;
• and
• display the overlapping portion in a display mode different from a display mode of a visible non-overlapping portion and a display mode of an invisible non-overlapping portion, the visible non-overlapping portion being a portion of the visible part out of the overlapping portion, and the invisible non-overlapping portion being a portion of the invisible part out of the overlapping portion.

A display control device for a vehicle to control a superimposed display of a content by a head-up display, the display control device comprising:

• an estimation unit that estimates a visible area that is a part of a road surface in a foreground included in an angle of view of the head-up display and is visible from an occupant, and an invisible area that is a part of the road surface in the foreground included in the angle of view of the head-up display and invisible from the occupant;
• and
• a display control unit that causes a route content presenting a scheduled traveling route of the vehicle to be superimposedly displayed on the road surface, wherein
• the display control unit distinguishes, in the route content, a visible part superimposed in the visible area, an invisible part superimposed in the invisible area, and an overlapping portion at which the visible part and the invisible part overlap, and
• the display control unit causes an invisible non-overlapping portion, which is a portion of the invisible part out of the overlapping portion, to be displayed in a display mode different from a display mode of the visible part, and causes the overlapping portion to be displayed in a display mode same as the visible part.
