Display system, electronic mirror system and movable-body apparatus equipped with the same
A display system includes a display unit, a housing, and a reflecting optical system. The display unit displays an image based on a captured image. The housing includes a housing room that houses the display unit and the reflecting optical system. The reflecting optical system reflects the image displayed on the display unit, thereby outputting the reflected image through an opening of the housing to the outside of the housing.
1. A display system comprising:
a display configured to display an image based on a captured image;
a magnifying optical system configured to magnify the image displayed on the display, and output the magnified image to a display position;
a housing configured to house the display and the magnifying optical system;
a light-transmissive cover configured to cover an opening of the housing; and
an optical attenuator configured to attenuate external light being incident on the display through the magnifying optical system, the optical attenuator being disposed in an optical path of the external light that is incident on the magnifying optical system,
wherein the light-transmissive cover transmits visible light and reflects infrared light.
2. The display system according to claim 1 ,
wherein the light-transmissive cover has a film which transmits the visible light and reflects the infrared light.
3. The display system according to claim 1 , wherein the magnifying optical system includes a mirror having a reflective surface.
4. The display system according to claim 1 , wherein the magnifying optical system includes a mirror having a reflective surface, the display system further comprising a background optical element disposed on an opposite site of the mirror from the reflective surface, wherein the background optical element is configured to perform at least one of light absorption and light scattering.
5. The display system according to claim 1 , wherein the optical attenuator is a beam splitter configured to partially reflect and partially transmit the external light.
6. The display system according to claim 1 , wherein the optical attenuator is a polarization filter having a filter polarizing axis.
7. An electronic mirror system comprising:
the display system according to claim 1 ; and
an imaging sensor configured to output the captured image.
8. A movable-body apparatus comprising:
the electronic mirror system according to claim 7 ; and
a body to which the electronic mirror system is mounted.
9. A display system comprising:
a display configured to display an image based on a captured image;
a magnifying optical system configured to magnify the image displayed on the display, and output the magnified image to a display position;
a housing configured to house the display and the magnifying optical system;
a light-transmissive cover configured to cover an opening of the housing; and
an optical attenuator configured to attenuate external light being incident on the display through the magnifying optical system,
wherein the light-transmissive cover transmits visible light and reflects infrared light, and
wherein the optical attenuator includes a mirror having a reflective surface.
10. A display system comprising:
a display configured to display an image based on a captured image;
a magnifying optical system configured to magnify the image displayed on the display, and output the magnified image to a display position; and
an optical attenuator configured to attenuate external light being incident on the display through the magnifying optical system, the optical attenuator being disposed in an optical path of the external light incident on the magnifying optical system,
wherein the magnifying optical system includes a mirror which reflects visible light and transmits infrared light.
11. The display system according to claim 10 , wherein the optical attenuator includes the mirror.
12. The display system according to claim 10 , further comprising a background optical element disposed on an opposite site of the mirror from the reflective surface, wherein the background optical element is configured to perform at least one of light absorption and light scattering.
13. The display system according to claim 10 , wherein the optical attenuator is a beam splitter configured to partially reflect and partially transmit the external light.
14. The display system according to claim 10 , wherein the optical attenuator is a polarization filter having a filter polarizing axis.
15. An electronic mirror system comprising:
the display system according to claim 10 ; and
an imaging sensor configured to output the captured image.
16. A movable-body apparatus comprising:
the electronic mirror system according to claim 15 ; and
a body to which the electronic mirror system is mounted.
