Head mounted display and method for controlling head mounted display
First Claim
1. A head mounted display comprising:
- an image display having an image light generator that generates image light based on image data and outputs the image light, the image display not only allowing a user who wears the image display around user'"'"'s head to recognize the image light in the form of a virtual image but also transmitting a surrounding scene;
a luminance processor that identifies luminance at each pixel of the virtual image;
an eye imaging camera that generates images of the user'"'"'s eyes; and
a controller that (1) determines the uses line-of-sight from the images of the user'"'"'s eyes, (2) generates an index based on (a) the luminance of each pixel of the virtual image, (b) the user'"'"'s line-of-sight and (c) illuminance of the transmitted surrounding scene, (3) compares the index with a first threshold set in advance and (4) causes the image light generator to generate display image light that differs from the initial image light in that at least part of the luminance thereof is changed based on a result of the comparison.

Abstract
A head mounted display includes an image display unit having an image light generation unit that generates image light based on image data and outputs the image light, the image display unit not only allowing a user who wears the image display unit around user'"'"'s head to recognize the image light in the form of a virtual image but also transmitting a surrounding scene, and a control unit that compares an index set based not only on luminance of initial image light generated based on initial image data that is original image data but also on illuminance of the transmitted surrounding scene with a first threshold set in advance and causes the image light generation unit to generate display image light that differs from the initial image light in that at least part of the luminance thereof is changed based on a result of the comparison.

12. A method for controlling a transmissive head mounted display including an image display having an image light generator that generates image light based on image data and outputs the image light, the image display not only allowing a user who wears the image display around user'"'"'s head to recognize the image light in the form of a virtual image but also transmitting a surrounding scene, the method comprising:
-
identifying luminance at each pixel of the virtual image; generating images of the uses eyes; determining the user'"'"'s line-of-sight from the images of the user'"'"'s eyes; generating an index based on (a) the luminance of each pixel of the virtual image, (b) the user'"'"'s line-of-sight and (c) illuminance of the transmitted surrounding scene; comparing the index with a first threshold set in advance; and causing the image light generator to generate display image light that differs from the initial image light in that at least part of the luminance thereof is changed based on a result of the comparison. - View Dependent Claims (14)
