  • Patent number: 10303920
    Abstract: Introduced here are computer programs and associated computer-implemented techniques for determining reflectance of an image on a per-pixel basis. More specifically, a characterization module can initially acquire a first data set generated by a multi-channel light source and a second data set generated by a multi-channel image sensor. The first data set may specify the illuminance of each color channel of the multi-channel light source (which is configured to produce a flash), while the second data set may specify the response of each sensor channel of the multi-channel image sensor (which is configured to capture an image in conjunction with the flash). Thus, the characterization module may determine reflectance based on illuminance and sensor response. The characterization module may also be configured to determine illuminance based on reflectance and sensor response, or determine sensor response based on illuminance and reflectance.

  • Patent number: 9933136
    Abstract: A lighting apparatus, in particular in the form of ceiling spots, with a perforated panel having at least one aperture for light to pass through, as well as a lens arranged so as to be concealed behind the perforated panel to emit a bundle of light beams that narrows on its way from the lens to the perforated panel, passes through the aperture for light to pass through, and broadens again after leaving the perforated panel. The lens is shaped in such a manner that a direct beam portion and/or direct light portion emitted without reflection from the lens and an indirect beam portion and/or indirect light portion emitted with reflection from the lens have essentially identical beam angles, and each essentially completely make up and/or fill out the overall bundle of light beams emitted by the lens.
