Imaging device and an imaging method

摘要

An optical lens 1 makes three components of visible light and near infrared light in different wavelength regions severally form images at different locations according to their wavelengths. An imaging element 2 has a plurality of pixels, which include pixels having a visible light detection section 6 and pixels having a near infrared light detection section 8 . The visible light detection section 6 has three detectors 3, 4 , and 5 which detect three components of visible light which form images at locations of different depths in the same pixel according to their wavelengths. The near infrared light detection section 8 has a near infrared light detector 7 which detects near infrared light which forms an image at a location of a depth different from the depths at which the three components of visible light form images. Clear color images with good color reproducibility are obtained by the visible light detection section 6 , and at the same time clear luminance information or monochrome images are obtained by the near infrared light detection section 8.
