Abstract
A display device configured to emit image light to display an image, and a camera or an illuminance sensor as an external light sensor configured to sense external light are provided, and the camera or the illuminance sensor is positioned to overlap a visually transparent light-guiding unit forming a front-of-eye part of the display device in an emission direction of the image light. Thus, the direction of sensing the external light in the illuminance sensor and the camera is set correspondingly to the direction of the line of sight of the viewer and a state, where these are located in the proximity of the eye of the viewer, is maintained.
Claims12
A wearable display device comprising:
- a display device configured to emit image light to display an image;
- an external light sensor configured to sense external light;
- and
- an illuminance sensor cover member that covers a surface of the display device, wherein:
- the external light sensor is located at a position where the external light sensor overlaps a front-of-eye part of the display device in an emission direction of the image light,
- in a front-rear direction, a gap is provided between the external light sensor and the front-of-eye part of the display device,
- in the front-rear direction, the external light sensor is located between a transparent part of the display device and the illuminance sensor cover member,
- the front-of-eye part of the display device is a part that is transparent while covering a front of an eye of a viewer wearing the wearable display device, and
- the external light sensor is located at a position spaced apart toward a light source side of the image light from an emission region of the image light in a transmission region of the external light.
A wearable display device comprising:
- a display device configured to emit image light to display an image;
- an external light sensor configured to sense external light;
- an illuminance sensor cover member that covers a surface of the display device, wherein:
- the external light sensor is located at a position where the external light sensor overlaps a front-of-eye part of the display device in an emission direction of the image light,
- in a front-rear direction, a gap is provided between the external light sensor and the front-of-eye part of the display device,
- in the front-rear direction, the external light sensor is located between a transparent part of the display device and the illuminance sensor cover member,
- the front-of-eye part of the display device is a part that is transparent while covering a front of an eye of a viewer wearing the wearable display device;
- and
- a light-controlling shade that is removably attached at the front-of-eye part of the display device, the light-controlling shade being configured to control the external light that passes therethrough, wherein
- the external light sensor is located at a position where the external light sensor receives the external light passing through the light-controlling shade when the light-controlling shade is attached.
A wearable display device comprising:
- a display device configured to emit image light to display an image;
