  • Patent number: 10617099
    Abstract: Various apparatus and associated methods involve a light source that provides light at wavelengths that substantially correlate to local maxima in the spectral sensitivity of a diurnal avian. In an illustrative example, the light source may output light primarily in wavelength bands that are not substantially absorbed by colored oil droplets and/or visual pigment in at least one type of cone in the eye of a diurnal avian. In some embodiments, the light source may include a light-emitting diode (LED) light source. Exemplary light sources may output spectral components to illuminate diurnal avians with local maxima of intensity at wavelengths that substantially correspond to local maxima in a spectral sensitivity visual response characteristic of the diurnal avians.

  • Patent number: 10582169
    Abstract: A system including an image capture system with a sensing efficiency that varies over a field of view of the image capture system may employ shaped illumination to compensate for the variation in the sensing efficiency. An illuminator may be configured to illuminate the field of view of the image capture system with illumination shaped to have higher intensity where the sensing efficiency is lower, e.g., at the periphery of the field over view. The imaging system may thus provide image data with more uniform signal-to-noise ratios. Image data from an illuminated scene may be manipulated using data from a non-illuminated scene to produce improved image data.
