Image display system and head-mounted display device

摘要

An image display system includes an image transmitter, a first display device that displays a first image, and a second display device that displays a second image, the second display device includes a display device side receiving unit that receives the second image, a display unit that displays the second image, a visual direction acquiring unit that acquires a current visual direction of the user, and a display device side transmitting unit that transmits the current visual direction, and the image transmitter includes a transmitter side receiving unit that receives the current visual direction, an extracting unit that extracts the first image as an image of a partial area in a whole image and the second image as an image of an area in response to the current visual direction in the whole image, and a transmitter side transmitting unit that transmits the first and second images.

主权项

1. An image display system comprising:
an image transmitter; a first display device that displays a first image received from the image transmitter; a second display device that is a see-through head-mounted display device worn on a head of a user and that displays a second image received from the image transmitter; and a virtual display surface surrounding the user on which a whole image is displayed, the second display device including:
a display device side reception unit that receives the second image,a display unit that displays the received second image,a visual direction acquisition unit that acquires a current visual direction of a user relative to the first display device, anda display device side transmission unit that transmits the acquired current visual direction, and the image transmitter including:
a transmitter side reception unit that receives the current visual direction from the second display device,an extraction unit that extracts as the first image an image of a partial area in the whole image corresponding to the image displayed on the first display device and extracts as the second image an image of a second partial area of the whole image corresponding to the current visual direction of the user, anda transmitter side transmission unit that transmits the first image and the second image, wherein
when the current visual direction of the user is directed toward the first display device, a drive control unit in the second display device opens a shutter to allow transmission of outside light from the first image displayed on the first display device through the second display device to be viewed by the user, andwhen the current visual direction of the user is in a direction other than a direction directed toward the first display device, the drive control unit in the second display device closes the shutter to shield outside light from transmitting through the second display device such that the second image is visible without interference from outside light.
