Benefits of technology

The technical effect of this patented system is its ability to take pictures by taking two types of lights - visible or near-visible for example blue (B) rays and infrared radiation. This allows us to see things clearly even if we don't want them under certain conditions like sunlight exposure without getting annoyed about it.

Problems solved by technology

The technical problem addressed in this patented method for creating images that can capture both brightness levels associated with natural or artificially colored objects without requiring multiple spectrally filtered lights at different times during imagery acquisition process.

Embodiment Construction

[0026]Hereinafter, some embodiments of the present invention will be described. The embodiments do not limit the invention according to the claims, and all the combinations of the features described in the embodiments are not necessarily essential to means provided by aspects of the invention.

[0027]FIG. 1 is a drawing for describing a configuration of a digital camera in an embodiment of the present invention. A digital camera 10 is capable of capturing an image of a subject luminous flux of an invisible band. The digital camera 10 includes an image-capturing lens 20 as an imaging optical system, and an image capturing device 100. Also, the digital camera 10 includes a multi-wavelength variable light source 230 that emits light of the near-infrared band. The multi-wavelength variable light source 230 includes a modulating unit 232 and a light-emitting unit 234. As described below, the modulating unit 232 modulates a spectral distribution of light emitted from the light-emitting unit 23

Abstract

An image capturing apparatus includes an image capturing device that captures an image of light from a subject, the light passing through each of wavelength band filters having invisible wavelengths as passbands, in which parts of the passbands of the filters whose center wavelengths are adjacent to each other mutually overlap, and a control unit that causes the image capturing device to capture an image of the light from the subject on which a first irradiation light is irradiated, the first irradiation light having a first spectral distribution in which parts of the respective passbands of the filters overlap with one another, and causes the image capturing device to capture an image of the light from the subject on which a second irradiation light is irradiated, the second irradiation light having a second spectral distribution in which parts of the respective passbands of the filters overlap with one another.
