Vehicle display device, imaging system, and lighting device

Abstract

The present invention relates to a vehicle display device, an imaging system, and a lighting device. It is a vehicle display device that is mounted on a vehicle and displays information. It is equipped with a near-infrared light irradiating part (80, 280, 380, 480, 580, 680, 780, 880, 980, 1080, 1180), and includes The near-infrared light of the light with the wavelength of the upper limit of visible light is irradiated to the visual confirmation side; The upper wavelength of light is camouflaged. It is an imaging system that is arranged inside a vehicle display device that displays information about a vehicle, and that illuminates a subject in the vehicle to capture a photograph. A photographing unit (60) for photographing a subject. The light of the upper limit of the visible light irradiated by the near-infrared light irradiating part is disguised by the disguising part provided in the vehicle display device.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application is based on Japanese Patent Application No. 2017-128258 filed on June 30, 2017, Japanese Patent Application No. 2018-64210 filed on March 29, 2018, and Japanese Patent Application No. filed on June 30, 2017 2017-128260 and Japanese Patent Application No. 2018-90780 filed on May 9, 2018, the contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to a display device for a vehicle, a photographing system, and a lighting device. Background technique [0004] Conventionally, a photographing system that illuminates and photographs a photographic subject in a vehicle is known. The system disclosed in Patent Document 1 includes a near-infrared light irradiating unit and an imaging unit that are arranged on the lower side of the lower cover of the steering column. The near-infrared light irradiation section irradiates near-infrared light including light ...

AI Technical Summary

Problems solved by technology

However, in this structure, when the occupant of the vehicle visually confirms the information displayed through the vehicle meter device, at the same time he visually confirms the light of the upper limit of the visible light in the near-infrared light irradiated by the near-infrared light irradiation unit, and the occupant may be worried. give mixed impressions

[0012] Although the light of the wavelength (780-830nm) of the upper limit of visible light included in near-infrared light has poor sensitivity, the occupant can perceive it through visual confirmation.

Furthermore, since the infrared light projector of Patent Document 1 emits such near-infrared light including light of the upper limit wavelength of visible light toward the occupants in the form of a point light source, the luminosity per unit area of ​​the light of the upper limit of visible light is large. , the light is easily perceived by the occupant

Therefore, since light with a wavelength of the upper limit of visible light is perceived, there is a concern that the appearance of the lighting device will be impaired and the occupant may be given a complicated impression.
