Rear view mirror with built-in camera
First Claim
1. A rear view mirror with built-in camera, comprising:
- a mirror housing configured for mounting to a vehicle and including a mirror for visual checking purposes;
an infrared projection device located adjacent the mirror housing and including an infrared light source for irradiating infrared light in an infrared irradiation direction and onto an image capture region for the camera, the camera being capable of sensing visible light and infrared light and located adjacent the mirror housing; and
a light transmission cover positioned in the infrared irradiation direction of the infrared light source and being formed from a material that is substantially impenetrable to visible light and that transmits substantially only infrared light, and being attached to the mirror housing in an integral manner.

Abstract
A housing device, such as rear view mirror, with built-in camera can include an infrared projection device with an infrared light source for irradiating infrared light onto an image capture region for the camera. The camera can display a sensitivity to visible light and infrared light, and can be built into the mirror housing which is mounted to a vehicle and contains a mirror used for visual checking purposes. The infrared projection device can include a light transmission cover. The cover can be positioned in an infrared irradiation direction of the infrared light source, can be formed from a material that is impenetrable to visible light and transmits only infrared light, and can be attached to the mirror housing in an integral manner.

11. A rear view mirror with built-in camera, comprising:
-
a mirror housing which is configured for mounting to a vehicle and contains a mirror used for visual checking purposes; and
an infrared projection device with an infrared light source for irradiating infrared light onto an image capture region for the camera which is capable of sensing visible light and infrared light and is built into the mirror housing, wherein the infrared projection device includes, a light transmission cover, which is positioned in an infrared irradiation direction of the infrared light source, is formed from a material that is substantially impenetrable to visible light and transmits substantially only infrared light, is attached to the mirror housing in an integrated manner, and includes lens cuts formed at an inside surface thereof, for controlling light distribution characteristics of light from the infrared light source of the infrared projection device, and a light transmission spectrum of the material of the transmission cover intersects an emission spectrum of the infrared light source, which has been normalized relative to a peak intensity of the infrared light source, at a point on a long wavelength side of a peak wavelength of the infrared light source, and increases from short wavelength bands to long wavelength bands.

19. A vehicle camera device, comprising:
-
a housing configured for mounting to a vehicle;
a camera located adjacent the housing, the camera being sensitive to visible light and infrared light;
an infrared light source located adjacent the housing and capable of irradiating infrared light in an infrared irradiation direction and towards an image capture region for the camera;
a light transmission cover positioned in the infrared irradiation direction of the infrared light source and being formed from a material that is substantially impenetrable to visible light and that transmits substantially only infrared light, and including at least one lens portion configured to redirect the light emitted from the infrared irradiation direction into a second different direction. - View Dependent Claims (20)
