Abstract: A projection-type image display device includes a first housing and a second housing. The first housing houses a light source unit configured to emit light, an image generating unit configured to modulate the light from the light source unit according to a video input signal to generate image light, and a projecting unit configured to project the image light generated by the image generating unit. The second housing includes an output unit configured to output a light signal and/or an input unit configured to input a light signal which are/is exposed and arranged on a surface of the second housing.

Abstract: A projection-type image display apparatus includes a light source unit, an image generating unit that generates image light according to an input video signal, a light-guide optical system that guides the light from the light source unit to the image generating unit, a projection optical system that projects the image light generated by the image generating unit, and a controller. The controller has a display mode in which the image light is projected and an illumination mode in which the light from the light source unit is emitted as illumination light. The controller controls the optical system to focus illumination light from the projection optical system on a projection surface, in the display mode, and to focus illumination light from the projection optical system at a position different from the projection screen, in the illumination mode.
