摘要:
A video display apparatus has one display screen capable of displaying a video corresponding to each of a plurality of observers. An illumination unit emits a first luminous flux and a second luminous flux in at least two different directions in a time divisional manner. A transmission-type display element displays respectively in a time divisional manner by means of raster scanning a first video whose light source is the first luminous flux and a second video whose light source is the second luminous flux. An illumination switching unit sequentially switches two luminous fluxes in synchronism with movement of a boundary portion between the first video and the second video in a display screen of the transmission-type display element.

The present invention provides a novel head-mounted type image display device capable of displaying a lot of information with good viewability by multi-screens without impairing mobility of the device. The device comprises a plurality of eyepiece optical units 25Ru, 25Rd emitting image light to be displayed toward corresponding eye balls respectively and a head-mounting unit 11 for supporting the plurality of eyepiece optical units 25Ru, 25Rd and adapted to detachably attached to the head of an observer. The head-mounting unit 11 in a state where the unit is attached to the head of the observer supports the plurality of eyepiece optical units 25Ru, 25Rd such that an emitting optical axis of each eyepiece optical unit 25Ru, 25Rd substantially passes through the eyeball rolling center of the corresponding eyeball and, when the emitting optical axis of one eyepiece optical unit passes through a pupil of the corresponding eyeball thereof as a result of rolling of the eyes, the emitting optical axis of another eyepiece optical unit does not pass through a pupil of the corresponding eyeball thereof.

A spectacles-type image display device provided with an image output unit that includes a display element for displaying images and a projection lens for magnifying and projecting the images and a reflection unit that is disposed adjacent to at least one of spectacle lenses and reflects the image light output from the image output unit toward the eyeball is provided. The reflection unit is a reflection member having no refractive power and an effective luminous flux that is output from the image output unit and reaches the eyeball is configured so that the width of the luminous flux perpendicular to an optical axis is minimum at the reflection unit with respect to the optical axis cross-section in at least one direction.

A video display apparatus displays videos corresponding to a plurality of observers respectively and comprises a display device. A control unit controls a scan timing so that a sum of a video scanning period from an upper end to a lower end of the display device concerning one video input into the display device and a response period in the lower end of the display device is smaller than a field period of the video. The control unit allows an illumination system to emit light between the end of the response period of the lower end and the start of scanning of the next video in the upper end of the display device.

It is an object of the invention to provide a head mount type image display system that, albeit having a see-around and a see-through function, is small size and low weight, makes sure a large field of outside view and low power consumption with high-luminance electronic images, and is easy to use.A head mount type image display system 1 at least comprises a display device, an eyepiece optical system, an eyepiece window, an eyepiece window holder 2, a casing and a supporter 10 for fixing all these components onto a user's head. The casing covers the display device, the eyepiece window holder 2 holds the eyepiece window within a user's field of view, the eyepiece optical system forms a virtual image of an image displayed on the display device, the eyepiece window allows a light beam for forming the virtual image to be directed to a user's eye and leave it, and a member that forms the eyepiece window holder is such that, in a range of 10 mm or greater from the eyepiece window toward a base, a width of projection section in a user's visual axis direction is 4 mm or less except some projection, and has a see-around mechanism.
