Display device, display control method, and storage medium

Abstract

The present invention provides a display device, a display control method, and a storage medium capable of improving image visibility. The display device is equipped with: a light projecting device, which projects light including an image; an optical mechanism, which is arranged on the path of the light, and can adjust the optical distance to a virtual image; a concave mirror, which converts the light passing through the optical mechanism Reflection toward a reflector; a first actuator, which adjusts the optical distance; a second actuator, which adjusts the reflection angle of the concave mirror; a control device, which is based on the state of the vehicle or the surrounding conditions of the vehicle to determine the target optical distance and target reflection angle, and control the first actuator to make the optical distance close to the target optical distance, and control the second actuator to make the reflection angle close to the For a target reflection angle, when the target optical distance is equal to or less than a predetermined distance, the control device performs predetermined control to prevent the virtual image from becoming a ghost.

Description

technical field [0001] The invention relates to a display device, a display control method and a storage medium. Background technique [0002] Conventionally, there is known a head-up display device (hereinafter referred to as a HUD (Head Up Display) device) that displays an image related to basic information for the driver on a windshield (for example, refer to Patent Document 1). By using this HUD device to superimpose and display various signs indicating obstacles, attention reminders, and driving directions on the scenery in front of the vehicle, the driver can grasp various displayed information while maintaining the direction of the line of sight during driving. .
