Imaging and display system
Imaging and display system includes: a display; an optical system including a first mirror and a second mirror; a housing; a light-transmissive cover transparent to light and disposed to cover at least part of an opening of the housing; and a driver monitoring camera supported by a supporting body connected outside of the housing. First light emitted from the display passes through the light-transmissive cover via the optical system, and is reflected by a windshield toward a direction of the user. The driver monitoring camera captures an image of a driver shown on the light-transmissive cover by second light from a direction of the driver reflected by the windshield toward a direction of the light-transmissive cover.
1. An imaging and display system comprising:
a display that emits first light representing an image;
an optical system that includes at least one mirror;
a housing that has an opening and accommodates the display and the optical system;
a light-transmissive cover that has transparency to light and is disposed to cover at least part of the opening of the housing;
a support having a low-reflection outer surface and being connected outside of the housing to cover at least part of the light-transmissive cover; and
a camera supported by the support, wherein a low-reflection coating is provided on at least part of the camera, the low-reflection coating having a lower visible light reflectivity than a visible light reflectivity of the low-reflective outer surface of the support,
wherein the first light emitted from the display passes through the light-transmissive cover via the optical system, and is reflected by a display medium toward a direction of a user, and
the camera is disposed on a surface of the support, and captures an image of the user shown on the light-transmissive cover by second light from the direction of the user reflected by the display medium toward a direction of the light-transmissive cover, the surface of the support being a surface facing the light-transmissive cover.
2. The imaging and display system according to claim 1 ,
wherein a first infrared reflection layer is stacked on the light-transmissive cover, the first infrared reflection layer having a higher reflectivity for an infrared ray than for visible light and transparent to visible light, and
the camera is an infrared camera.
3. The imaging and display system according to claim 2 ,
wherein a second infrared reflection layer is stacked on the display medium, the second infrared reflection layer having a higher reflectivity for an infrared ray than for visible light and transparent to visible light.
4. The imaging and display system according to claim 3 ,
wherein the second infrared reflection layer includes two reflection layers,
one of the two reflection layers is provided on a surface of the display medium, the surface being a surface facing the user, and
a remaining one of the two reflection layers is provided on a surface of the display medium, the surface being a surface opposite the surface facing the user.
5. The imaging and display system according to claim 1 , further comprising:
an infrared-transmissive portion that is transparent to an infrared ray and has a higher reflectivity or absorptivity for light other than an infrared ray than for an infrared ray,
wherein the camera is an infrared camera and captures an image of the user, using an infrared ray that enters an imaging element inside the camera from the direction of the light-transmissive cover via the infrared-transmissive portion.
6. The imaging and display system according to claim 1 , further comprising:
a light source that is supported by the support and emits an infrared ray as third light,
wherein the camera is an infrared camera, and
the third light emitted from the light source is reflected by the light-transmissive cover toward a direction of the display medium and reflected by the display medium toward the direction of the user.
7. The imaging and display system according to claim 1 , further comprising:
a driving unit that shifts an optical axis of the camera; and
a controller that controls the driving unit, based on an image captured by the camera,
wherein the controller causes the driving unit to shift the optical axis of the camera when a second region in the image captured is a predetermined distance or less from a first region in which part of the user is shown, the second region having higher luminance than luminance of the first region.
8. The imaging and display system according to claim 1 , further comprising:
a second camera different from a first camera that is the camera;
a switcher that switches a camera used for imaging the user between the first camera and the second camera; and
a controller that controls the switcher, based on an image captured by the first camera,
wherein the controller causes the switcher to switch the camera from the first camera to the second camera when a second region in the image captured is a predetermined distance or less from a first region in which part of the user is shown, the second region having higher luminance than luminance of the first region.
