Image capturing apparatus and monitoring apparatus for vehicle driver
First Claim
1. A driver image capturing apparatus adapted for use in a vehicle, the driver image capturing apparatus comprising:
- a rear-view mirror mounted at a location obliquely upward and forward from a driver seat, the rear-view mirror including;
a first reflector for reflecting visible light and transmitting infrared radiation; and
a second reflector for reflecting infrared radiation, the second reflector being disposed behind the first reflector so as to be at a predetermined angle θ
relative to the first reflector;
a driver illuminating device adapted to emit infrared radiation to the rear-view mirror, the driver illuminating device being mounted at a location obliquely upward and backward from the rear-view mirror; and
an infrared camera with infrared sensitivity, the infrared camera being mounted so as to be pointed at a face of a driver in the driver seat.

Abstract
A driver image capturing apparatus includes an interior rear-view mirror, an infrared emitter, and an infrared camera. The mirror is mounted at a location obliquely upward and forward from a driver seat. Mounted at a location obliquely upward and backward from the mirror, the infrared emitter emits infrared radiation to the mirror. The camera is pointed at a face of a driver in the driver seat. The mirror has a first reflecting mirror and a second reflecting mirror. The first mirror reflects visible light and transmits infrared radiation. Disposed behind the first mirror at an angle θ relative to the first mirror, the second mirror reflects infrared radiation. The first mirror provides a field of rear vision to the driver. Infrared radiation emitted by the infrared emitter is delivered to the face of the driver through the first and second mirrors, reflected by the face, and received by the camera.
