Problems solved by technology

[0007] According to the near-infrared multi-band imaging device described in Non-Patent Document 2, it is possible to increase the accuracy of specific human faces. However, since near-infrared light with a wavelength of 870 nm and a wavelength of 970 nm is sequentially irradiated, it is necessary to obtain it during sequential lighting. and synchronous photography, etc., there are issues such as complexity and real-time

Embodiment Construction

[0045] Other objects and features of the present invention will become clear from the description of the following embodiments with reference to the accompanying drawings.

[0046] An embodiment of the present invention will be described in detail below with reference to the drawings. In the embodiments described below, since they are preferred embodiments of the present invention, technically there are various restrictions on constituent elements, types, combinations, shapes, relative installations, etc., but these are only examples, and the present invention It is not limited to this.

[0047] In the following embodiment, similar to Non-Patent Document 2, near-infrared light with two wavelengths of 870 nm and 970 nm is used, but the present invention is not limited thereto, and more than two wavelengths may be used. In general, the more the number, the more high-precision processing is possible.

[0048] figure 1 It is a configuration diagram showing the overall configura...

Abstract

An image pickup including a light emission portion (20) that irradiates an object with near infrared; and an image pickup portion (10) that receives a reflection light image of the object by the near infrared. The image pickup portion includes a lens array containing a substrate on which multiple lenses to respectively receive the reflection light image of the object by the near infrared are arranged; a light shield spacer that shields beams of light that have passed through the lens array from each other; a color filter separated into areas according to beams of light that pass through the light shield spacer, each of which transmits only particular beams of near infrared depending on the wavelengths thereof; and an image pickup element that simultaneously obtains multiple images of the object which are formed of each of the particular beams of near infrared having independent wavelengths that have passed through each of the areas of the color filter.

Description

technical field [0001] The present invention relates to an imaging device, and more specifically, to an imaging device for detecting a driving state of a driver, for example. Background technique [0002] In recent years, the driving state of the driver has been constantly detected and monitored as a driving support system. Generally, in order to detect the state of the driver, the method of taking pictures of the driver's face image through a camera built in the interior reflector (hereinafter referred to as "indoor reflector built-in camera") can be used. Wide illuminance changes from night to day can stably capture the image of the driver's face. [0003] In Non-Patent Document 1, an indoor reflective mirror built-in imaging device is described, which uses a near-infrared pulsed light projection method to stably capture the driver's face image from low illumination at night to high illumination during the day. camera. In this indoor reflective mirror built-in imaging d...
