Abstract

Infrared camera 5, infrared luminescence equipment 2, and shutter synchronous luminescence drive 7 are arranged in mirror case 6 at the back side of cold mirror 3, infrared luminescence equipment 2 synchronizes with shutter operation of the infrared camera 5 by the shutter synchronous luminescence drive 7, to do intermittent luminescence operation. And clear and exact stable photography picture is obtained without being influenced by disturbance light, without a driver and a fellow passenger who are a photographic subject having sense of incongruity in any way, without making them conscious of existence of an infrared camera also.

Claims

1. A mirror equipment for a vehicle with a built-in camera, which has a cold mirror equipped in a mirror case, and in which light in the range of from near-infrared to infrared region emitted with an infrared luminescence equipment is irradiated through the cold mirror onto a photographic subject in the vehicle and the capotric light is photoed with the infrared camera capable of taking photograph,

said infrared camera and said infrared luminescence equipment being arranged in the mirror case at the back side of the cold mirror.

3. The mirror equipment for a vehicle with a built-in camera as set forth in claim 1 or 2, wherein said cold mirror comprises a multilayer film in such a manner that an SiO₂ thin film and a TiO₂-Ba thin film are laminated repeatedly growing into the multilayer films.

4. The mirror equipment for a vehicle with a built-in camera as set forth in claim 1, 2, or 3, wherein said cold mirror is used as a rearview mirror of a car.

5. The mirror equipment for a vehicle with a built-in camera as set forth in claim 1, 2, or 3, wherein said infrared camera is an infrared digital camera, which presents the pattern recognition in image-processing equipment regarding the photoed picture signal as picture information.

6. The mirror equipment for a vehicle with a built-in camera as set forth in claim 1, 2, or 3, wherein said shutter of infrared camera performs shutter operation at intervals of once per 10-60 seconds, the shutter speed being set at {fraction (1/250)} to 100000 seconds.

2. A mirror equipment for a vehicle with a built-in camera, which has a cold mirror equipped in a mirror case, and in which light in the range of from near-infrared to infrared region emitted with an infrared luminescence equipment is irradiated through the cold mirror onto a photographic subject in the vehicle and the capotric light is photoed with the infrared camera capable of taking photograph, said infrared luminescence equipment performing intermittent luminescence operation with a shutter synchronous luminescence drive synchronizing with shutter operation of an infrared camera, and the infrared camera, infrared luminescence equipment, and the shutter synchronous luminescence drive being arranged in the mirror case at the back side of the cold mirror.
