ABSTRACT:
An optical lens1makes 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 element2has a plurality of pixels, which include pixels having a visible light detection section6and pixels having a near infrared light detection section8. The visible light detection section6has three detectors3, 4, and5which 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 section8has a near infrared light detector7which 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 section6, and at the same time clear luminance information or monochrome images are obtained by the near infrared light detection section8.
