A display unit is configured to display visual information that is visually recognized and superimposed on an external scene. A detection unit is configured to detect an event possibly causing danger by visually recognizing the visual information. A mounting unit is configured to be mountable on a head of a user and support the display unit and the detection unit. A controller is configured to suppress display of the visual information on the display unit in a case that the event is detected. Embodiments of the present invention can be applied to any of a terminal apparatus, a communication method, or a program.

An image generating section reads image data from an image storing section to generate an original image in keeping with the attitude of a head-mounted display. A lens distortion correcting section generates a primary image by correcting beforehand the original image in a manner canceling out the distortion thereof that appears when viewed through lenses of the head-mounted display. A different image embedding section generates an embedded image by embedding a different image into an unused area of a rectangular format for transmitting the primary image. An HDMI transmitting section transfers the embedded image to the head-mounted display.

Systems, methods, and media for projecting light to indicate a device status are provided. In accordance with some implementations of the disclosed subject matter, systems for projecting light to indicate a device status are provided, the systems comprising: a hardware processor that: determines a light status; determines whether to turn a light source on; selects a light format corresponding to the light status; projects light of a light source according to the light format; and determines whether to turn the light source off.

Implementations described herein generally relate to the use of display screens. More specifically, implementations generally relate to a large format transmissive and self-emissive display screen where the display screen includes multiple screens coupled together using transparent adhesive tape. Implementations described herein minimize internal reflections visible to screen viewers when an edge of the adhesive layer is scanned by a beam spot produced by a scanning beam in a scanning beam system having multiple screens held together by the adhesive layer to form a seamless viewing screen. In some implementations, the internal reflections are minimized by applying the adhesive layer between horizontal and vertical seams between each screen of the multiple screens wherein the adhesive layer has non-straight edges so as to minimize the total surface area of the edge of the adhesive layer that falls within the beam spot produced by the scanning beam.

An image display apparatus includes image displaying sections that present displayed images to a user and allow the user to visually recognize outside light, a first light adjusting member that is disposed on an outside-facing side of the image displaying sections and adjusts the transmittance based on outside light incident on the first light adjusting member, and a second light adjusting member that is disposed between the image displaying sections and the first light adjusting member and adjusts the transmittance in accordance with the transmittance of the first light adjusting member.

There is provided a display control device capable of ensuring the user's field of vision while keeping the user safe when the user is using a see-through head-mounted display, the display control device including: a situation acquisition unit configured to acquire information about a situation where a see-through display is being used, and a display control unit configured to perform display control on the see-through display using the information acquired by the situation acquisition unit so that a display of the information on the see-through display gradually becomes clearly visible.

Control of luminance of a light-emitting unit is enabled without separately providing a device for measuring the luminance of the light-emitting unit. A posture specifying unit specifies a posture of a user-controllable object including the light-emitting unit that emits light at luminance according to drive current, the posture specified based on a posture specifying image taken by a camera, the posture specifying image including an image of the light-emitting unit. A luminance information specifying unit specifies information indicating the luminance of the light-emitting unit based on a luminance specifying image taken by the camera that takes the posture specifying image, the luminance specifying image including an image of the light-emitting unit. A drive current control unit controls the drive current of the light-emitting unit based on the specified information indicating the luminance of the light-emitting unit.
