Abstract
An optical lensmakes 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 elementhas a plurality of pixels, which include pixels having a visible light detection sectionand pixels having a near infrared light detection section. The visible light detection sectionhas three detectors, andwhich 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 sectionhas a near infrared light detectorwhich 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, and at the same time clear luminance information or monochrome images are obtained by the near infrared light detection section
