  • Patent number: 10113910
    Abstract: An image capture device, such as a smartphone or point of sale scanner, is adapted for use as an imaging spectrometer, by synchronized pulsing of different LED light sources as different image frames are captured by the image sensor. A particular implementation employs the CIE color matching functions, and/or their orthogonally transformed functions, to enable direct chromaticity capture. These and various other configurations of spectral capture devices are employed to capture spectral images comprised of spectral vectors having multi-dimensions per pixel. These spectral images are processed for use in object identification, classification, and a variety of other applications. Particular applications include produce (e.g., fruit or vegetable) identification. A great variety of other features and arrangements are also detailed.

  • Patent number: 10031322
    Abstract: The invention relates to an electronic image pickup system whose depth dimension is extremely reduced, taking advantage of an optical system type that can overcome conditions imposed on the movement of a zooming movable lens group while high specifications and performance are kept. The electronic image pickup system comprises an optical path-bending zoom optical system comprising, in order from its object side, a 1-1st lens group G1-1 comprising a negative lens group and a reflecting optical element P for bending an optical path, a 1-2nd lens group G1-2 comprising one positive lens and a second lens group G2 having positive refracting power. For zooming from the wide-angle end to the telephoto end, the second lens group G2 moves only toward the object side. The electronic image pickup system also comprises an electronic image pickup device I located on the image side of the zoom optical system.

  • Patent number: 10024521
    Abstract: An optical element for influencing a light emitted by a light source, having a front side facing away from and a rear side facing the light source. A recess for the input of the light is formed on the rear side, and a deflecting surface region is formed. On the front side, a frontside surface region is formed. First light beams (L1) entering the optical element via the recess, are totally reflected at the deflecting surface region and exit the optical element via the front-side surface region. The front-side surface region causes the second light beams (L2) of the light, which enter the optical element via the recess and then hit the front-side surface region directly, to undergo total reflection. High intensity light beams from the light source can be distributed onto a larger region reducing the maximum luminance of the light emitted via the front-side surface region.
