Abstract:
A viewer includes a multifocal lens capable of setting one of a plurality of focal lengths. When a measuring section detects a change in gazing point distance, a selection section selects a focal length to be set among the plurality of focal lengths, and a determiner determines a time duration before a focal length of the multifocal lens is changed. A controller changes the focal length of the multifocal lens when a detector detects a blink or saccadic eye movement of the user before the determined time duration elapses.
Abstract:

Abstract:
A viewer includes a varifocal lens and a lens controller that adjusts a focal length of the varifocal lens, and can adjust a focal point in accordance with eye movement of the user. When a 3D image viewing detector detects 3D image viewing by the user, a focal length fixing section instructs a lens controller to fix a focal length of the varifocal lens irrespective of eye movement of the user.
Abstract:
A three-dimensional (3D) video display apparatus includes: a viewing action detecting unit which detects whether or not a viewing state of a user who views a plurality of 3D video display screens with a viewing target being changed between the 3D video display screens has changed a predetermined number of times or more in a predetermined time period; and a control unit which restricts user's viewing action of viewing a 3D video image displayed by an image display unit when the viewing action detecting unit detects that the viewing state of the user has changed the predetermined number of times or more in the predetermined time period.
Abstract:
Provided is a three-dimensional image display system including: eyeglasses including a type information transmission unit which transmits type information of the eyeglasses and a potential information transmission unit which transmits a biopotential of a viewer as potential information; and a three-dimensional display TV including a type information reception unit which receives the type information, an electrode position determination unit which determines, based on the received type information, a position of an electrode included in the eyeglasses, a potential information reception unit which receives the transmitted potential information, and a wearing conditions determination unit which determines wearing conditions of the viewer wearing the eyeglasses, based on the determined electrode position and the received potential information.
Abstract:
A visual fatigue level measuring device includes: a video presenting unit which presents 3D video; a test period determining unit which determines two or more time periods each of which is for a test for measuring a level of visual fatigue; an eye movement obtaining unit which obtains data indicating eye movements of left and right eyes of a player with respect to the presented video; an eye movement extracting unit which extracts, from the obtained eye movement data, eye movement data in each of the two or more time periods determined by the test period determining unit; an eye movement comparing unit which compares eye movements in the two or more time periods based on the extracted data; and a fatigue level determining unit which determines the level of visual fatigue of the player based on the comparison result.
Abstract:
A three-dimensional display device for displaying a three-dimensional image, including: a gaze point obtaining unit which obtains a position of a gaze point of a viewer; a fusional area determination unit which determines a fusional area where binocular fusion is allowed, based on the obtained position of the gaze point; a correction unit which corrects the three-dimensional image so as to suppress display of an object that is included in the three-dimensional image outside the fusional area; and a display unit which displays the corrected three-dimensional image.
Abstract:
A stereoscopic video processing apparatus includes: a switch operation detection unit which detects a switch operation, made by a user, that is an operation to select a channel of a three-dimensional (3D) video or an operation for a fast-forward playback, a rewind playback, skipping, or locating a cue point of a 3D video; a frequency determination unit which determines a detection frequency indicating the number of switch operations per unit of time detected by the switch operation detection unit; and a video processing unit which performs processing to reduce a difference in depth between 3D videos before and after switching of the 3D videos when the detection frequency per unit of time determined by the frequency determination unit is higher than or equal to a predetermined frequency.
Abstract:
