Abstract
A head-mounted display device that is mounted on the head of an observer and forms a virtual image before the eyes of the observer includes: a display device that forms an image, which is the source of image light, from image data; a light source that emits the image light representing the formed image; a light guide unit that forms a virtual image from the emitted image light; and a display control unit that turns off the light source and changes the head-mounted display device to a suspension mode when a suspension request is received from the outside.
Claims13
A head-mounted display device configured for mounting on a head of an observer and forming a virtual image before eyes of the observer, the head-mounted display device comprising:
- a display device that forms an image, which is a source of image light, from image data;
- a light source that emits the image light representing the formed image;
- a light guide unit that forms a virtual image from the emitted image light;
- and
- a display control unit that turns off the light source to prevent formation of the virtual image and changes the head-mounted display device to a suspension mode when a suspension request is received from an outside, the display control unit continuing forming the image during the suspension mode with the light source turned off.
A control method for a head-mounted display device configured for mounting on a head of an observer and forming a virtual image before eyes of the observer, the control method comprising:
- (a) forming an image, which is a source of image light, from image data;
- (b) emitting the image light representing the formed image;
- (c) forming a virtual image from the emitted image light;
- and
- (d) stopping the emission of the image light in the step (b) to prevent formation of the virtual image and changing the head-mounted display device to a suspension mode when a suspension request is received from an outside, while continuing forming the image during the suspension mode.
A head-mounted display device configured for mounting on a head of an observer and forming a virtual image before eyes of the observer, the head-mounted display device comprising:
- a display device that forms an image, which is a source of image light, from image data;
- a light source that emits the image light representing the formed image;
- a light guide unit that forms a virtual image from the emitted image light;
- and
- a display control unit that turns off the light source and changes the head-mounted display device to a suspension mode when a suspension request is received from an outside,
- wherein, when the head-mounted display device is in the suspension mode, the display control unit stops the formation of an image by the display device after elapse of a first time set in advance, transitions an operation state of the head-mounted display device to a standby state, in which power consumption is low compared with an active state in which formation of a virtual image is possible, after elapse of a second time set in advance, and stops supply of electric power to the head-mounted display device after elapse of a third time set in advance.
A head-mounted display device configured for mounting on a head of an observer and forming a virtual image before eyes of the observer, the head-mounted display device comprising:
- a display device that forms an image, which is a source of image light, from image data;
- a light source that emits the image light representing the formed image;
- a light guide unit that forms a virtual image from the emitted image light;
- and
- a display control unit that turns off the light source to prevent formation of the virtual image and changes the head-mounted display device to a suspension mode in response to receiving a suspension request, and the display control unit continuing to drive the light guide unit during the suspension mode.
