## Abstract

A head-mounted display device includes: a medium recognizing section that detects information that is viewable by a user; a display section that performs display to be viewable by the user; and an update processing section that causes the display section to display, to overlap with at least a part of the information detected by the medium recognizing section, new information corresponding to the information.

## Claims

### Claim 1

A display device comprising:
a detecting section that detects information that is viewable by a user;
a display section that performs display to be viewable by the user; and
a control section that causes the display section to display, to overlap with at least a part of the information detected by the detecting section, different information corresponding to the information.

### Claim 2

A display device comprising:
a display section that displays an image viewed to overlap with an outside scene;
a medium detecting section that detects a medium viewed as the outside scene; and
a control section that arranges and causes the display section to display, to overlap with at least a part of information recorded on the medium, new information corresponding to the information in an overlap area.

### Claim 3 (depends on 2)

The display device according to claim 2, further comprising:
an attribute determining section that determines an attribute of the information recorded on the medium; and
an information obtaining section that obtains the new information corresponding to the information on the basis of the attribute of the information that is a target with which the new information overlaps by the display section,
wherein the control section causes the display section to display the new information obtained by the information obtaining section.

### Claim 4 (depends on 3)

The display device according to claim 3,
wherein the control section selects update target information from the information recorded on the medium on the basis of the attribute of the information determined by the attribute determining section.

### Claim 5 (depends on 4)

The display device according to claim 4,
wherein the control section selects information from which the new information is obtainable by the information obtaining section from among the information recorded on the medium, as the update target information.

### Claim 6 (depends on 2)

The display device according to claim 2,
wherein the control section arranges the new information according to the shape and size of an area where information on the medium is hidden.

### Claim 7 (depends on 2)

The display device according to claim 2,
wherein the display device is provided as a head-mounted display device, and
wherein the medium detecting section includes a photographing section that photographs the outside scene in a range that overlaps with the image displayed by the display section, and an image processing section that detects the medium from an image photographed by the photographing section.

### Claim 8 (depends on 2)

The display device according to claim 2,
wherein the display device is a head-mounted display device that causes a user to view an image,
wherein the display section includes:
an image light generating section that generates and emits image light for display of an image using display image data; and
an optical member that guides the emitted image light to eyes of the user, and
wherein light of the outside scene passes through the optical member and is incident onto the eyes of the user together with the image light.

### Claim 9

A control method of a display device, comprising:
detecting information that is viewable by a user; and
displaying, to overlap with at least a part of the detected information, new information corresponding to the information, by a display section that performs display to be viewable by the user.

### Claim 10

A control method of a display device that includes a display section that displays an image viewed to overlap with an outside scene, the method comprising:
detecting a medium viewed as the outside scene; and
arranging and causing the display section to display, to overlap with at least a part of information recorded on the medium, new information corresponding to the information in an overlap area.
