A display control device for controlling a virtual image display, wherein

• said virtual image display can display a display object being a virtual image which can be visually recognized from a driver's seat of a vehicle through a windshield of said vehicle in a virtual image position defined by a virtual image direction which is a direction of said virtual image on a basis of a specific position of said vehicle and a virtual image distance which is a distance to said virtual image on a basis of said specific position, and
• said display control device comprises:
• a processor to execute a program;
• and
• a memory to store said program which, when executed by said processor, performs processes of:
• obtaining a relative position of an information-to-be-provided object which is a point or a feature associated with information with which a driver of said vehicle is provided, using said display object, and said vehicle;
• and
• controlling a display of said virtual image display, and
• said processor changes a virtual image distance of said display object in accordance with said relative position of said information-to-be-provided object corresponding to said display object and said vehicle, wherein,
• when said vehicle enters a predetermined area on a basis of said information-to-be-provided object, said processor causes said virtual image distance of said display object to be smaller than said virtual image distance before said vehicle enters said predetermined area.
