Problems solved by technology

[0006] However, in the conventional technology, in order to overlap and display the image and the scenery, light is projected on a light-transmitting object such as the windshield, and a phenomenon called ghosting occurs in which two images with different brightness are superimposed on each other. Sometimes the visual confirmation of the image is reduced

Embodiment Construction

[0041] Hereinafter, embodiments of a display device, a display control method, and a storage medium of the present invention will be described with reference to the drawings. The display device is mounted on a vehicle (hereinafter, referred to as a vehicle M), and superimposes an image on a scenery for human visual confirmation. The display device is, for example, a HUD device. As an example, the display device is a device that projects light including an image onto the windshield of the vehicle M so that a viewer can visually recognize a virtual image. The viewer is the driver of the vehicle M, for example. The display device is not limited thereto, and the display device may allow passengers other than the driver (for example, a passenger seated in the passenger seat, etc.) to visually recognize the virtual image.

[0042] In the following description, the positional relationship and the like will be described using an XYZ coordinate system as appropriate. The Z direction...

Abstract

A display device, a display control method, and a storage medium are provided. A display device includes a light projection device which projects light including an image onto a reflector reflecting incident light to allow an observer to visually recognize the image included in the light reflected by the reflector as a virtual image, and a control device which causes the light projection device tooutput first light including a first image in a first case where a surrounding brightness is equal to or greater than a threshold value and causes the light projection device to output second light including a second image in a second case where the surrounding brightness is less than the threshold value.

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). Using this HUD device, various signs indicating obstacles, alerts, and driving directions are superimposed and displayed on the scenery in front of the vehicle, so that the driver can grasp the various signs displayed while maintaining the direction of the line of sight during driving. information. [0003] prior art literature [0004] Patent Document 1: Japanese Patent Laid-Open No. 2017-91115 [0005] The problem to be solved by the invention [0006] However, in the conventional technology, in order to overlap and display the image and the scenery, light is projected on a light-transmittin...
