The present application is based on, and claims priority from JP Application Serial Number 2019-140781, filed Jul. 31, 2019, the disclosure of which is hereby incorporated by reference herein in its entirety.

BACKGROUND

1. Technical Field

The present disclosure relates to a technique for superimposing and displaying an image on an outside scene.

2. Related Art

There has been known a technique for causing a display device to superimpose and display an image on an outside scene, information concerning an object being displayed on the display device when an operator points at, with a hand, the object displayed on the display device (JP-A-2018-28922 (Patent Literature 1)).

In the related art, a movement of the hand of the operator is recognized using an image captured by an image sensor. In this case, when the hand of the operator is present outside a detection range of the image sensor, the hand of the operator is not recognized by the image sensor. Consequently, although the operator points at the object, it could occur that the information concerning the object is not displayed. Such a problem is not limited to the technique for recognizing the movement of the hand of the operator and displaying the information concerning the object and is common to a technique for recognizing a movement of a pointer and displaying information concerning a target related image.

SUMMARY

According to an aspect of the present disclosure, a display device is provided. The display device includes: a display that displays an image while allowing light from outside scene to be transmitted through the display; a camera that captures images the outside scene; one or more processors configured to: recognize a movement of a pointer using at least two captured images captured by the camera; recognize a target in the outside scene using the captured images; and display, on the display, a target related image, which is the image related to the target recognized by the target recognizing section, wherein the one or more processors are further configured to: display, on the display, related information related to the target related image when the movement of the pointer within a range overlapping the target related image is recognized by the pointer recognizing section; and change a display state of the target related image according to whether the target related image is present within an imaging range of the camera.
