Abstract
Abstract A head-mounted image display device with a good operability and a data processing apparatus including such a display device. A head-mounted image display device wherein a liquid crystal panel and an enlarging optical system are housed in a frame and wherein images generated on the liquid crystal display panel through the enlarging optical system are visible in the field of view in front of the frame comprises a first direction detection means ( 107 ) disposed in part of the frame ( 101 ) for detecting the direction of the user's head; an observation point detection means ( 109 ) disposed in part of the frame for detecting the user's line of sight; a trigger input means ( 4 ) for transmitting trigger signals; and an image generation means ( 3, 105 ) for controlling images generated on the liquid crystal display panel based on signals from the first direction detection, observation point detection, and trigger input means.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
A head-mounted image display device wherein a liquid crystal display panel and an enlarging optical system are housed in a frame and wherein images generated on said liquid crystal display panel are visible through said enlarging optical system in the field of view in front of said frame, comprising: an observation point detection means for detecting a line of sight of a user of said device in the horizontal or vertical directions; and an image generation means for segmenting the display area into a first display area for displaying images and a second display area for display attributes of images displayed in said first display area, and switching between said first and second display areas based on the output of said observation point detection means.
Claim 2
Dependent Claim
125 words
A head-mounted image display device wherein a liquid crystal display panel and an enlarging optical system are housed in a frame and wherein images generated on said liquid crystal display panel are visible through said enlarging optical system in the field of view in front of said frame, comprising: an observation point detection means for detecting a line of sight of a user of said device in the horizontal or vertical directions; and an image generation means for segmenting the display area into a first display area for displaying images and a second display area for display attributes of images displayed in said first display area, and switching between said first and second display areas based on the output of said observation point detection means.
Claim 3
Dependent Claim
47 words
An image display device according to claim 1 wherein said image generation means can switch between said first and second display areas based on the output of said observation point detection means, and controls attribute data shown in said second display area according to voice input signals.
Claim 4
Dependent Claim
70 words
An image display device according to claim 1 , further comprising a direction detection means for detecting the direction of the head of said user, said observation point detection means being disposed in part of said frame, said image generation means scrolling said images visible through said enlarging optical system based on the output of said direction detection means from a virtual display screen displaying a plurality of virtual images.
Claim 5
Dependent Claim
137 words
A head-mounted image display device wherein a liquid crystal display panel and an enlarging optical system are housed in a frame and wherein images generated on said liquid crystal display panel are visible through said enlarging optical systems in the field of view in front of said frame, comprising: an observation point detection means for detecting a line of sight of a user of said device in the horizontal or vertical directions, and an image generation means for segmenting the display area into a first display area for displaying attributes of an image, and switching between said first and second display areas based on the output of said observation point detection means to display in said second display area for displaying attributes of an image geometry or operation models to be incorporated in said first display area.
Claim 6
Dependent Claim
137 words
A head-mounted image display device wherein a liquid crystal display panel and an enlarging optical system are housed in a frame and wherein images generated on said liquid crystal display panel are visible through said enlarging optical systems in the field of view in front of said frame, comprising: an observation point detection means for detecting a line of sight of a user of said device in the horizontal or vertical directions, and an image generation means for segmenting the display area into a first display area for displaying attributes of an image, and switching between said first and second display areas based on the output of said observation point detection means to display in said second display area for displaying attributes of an image geometry or operation models to be incorporated in said first display area.
Claim 7
Dependent Claim
29 words
An image display device according to claim 4 wherein geometrical data or camera work to be incorporated in said first display area is displayed in said second display area.
Claim 8
Dependent Claim
