  • Patent number: 10324361
    Abstract: A free-form lens (for example a phase modulator, lens or deformable mirror) may be made to reproduce a light pattern specified by image data. Source regions on the free-form lens are mapped to target regions areas on an image. Areas of the source regions are adjusted to vary the amount of light delivered to each of the target regions. Adjustment of the source areas may be achieved using a L-BFGS optimization which preferably incorporates smoothness and curl regularizers. Embodiments apply parallel processing to obtain control values for a free form lens in real time or near real time. Apparatus may process image data and display an image by controlling a dynamically variable free form lens using the processed image data.

  • Publication number: 20190124304
    Abstract: Light projection systems and methods may comprise combining light from two or more projectors, Each projector may be controlled so that the combined light output of the projectors matches a target for the projected light. In some embodiments optimization is performed to generate image data and control signals for each of the projectors.

  • Patent number: 10192517
    Abstract: Source image content is adapted to a target display. Target image content associated with the target display is provided. A histogram is computed for the target image content. A prominent feature present in the target histogram is determined. A histogram is computed for the source image content. The source content histogram is manipulated to reflect the determined target histogram prominent feature(s). Adapted source image content is generated based on the manipulated source histograms(s). Another prominent feature present in the target histogram is determined. The source histogram is further manipulated to reflect the other prominent determined target histogram features. Further adapted source image content is generated based on the further manipulated source histogram if the adapted source image content has insufficient image quality and perceptual color characteristics.

  • Publication number: 20190007660
    Abstract: Image display apparatus and methods may use a single imaging element such as a digital mirror device (DMD) to spatially modulate plural color channels. A color channel may include a light steering element such as a phase modulator. Steered light from a light steering element may be combined with or replaced by additional light to better display bright images. These technologies may be provided together or applied individually.

  • Patent number: 10171779
    Abstract: Light projection systems and methods may comprise combining light from two or more projectors. Each projector may be controlled so that the combined light output of the projectors matches a target for the projected light. In some embodiments optimization is performed to generate image data and control signals for each of the projectors. Embodiments may be applied in image projecting applications, lighting applications, and 3D stereoscopic imaging.

  • Publication number: 20180376115
    Abstract: Undesirably high energy-consumption in illuminating devices can be caused at least in part by wasted (attenuated) light. Optically efficient illumination systems that may be used to project light, including images, use light redirection. Phase modulating devices may be applied to create desired light fields. Some embodiments provide dual or multiple modulation display or projection systems in which some or all of the modulators not only attenuate amplitude, but also amplify amplitude, or change the phase, frequency and polarization of the light provided by the light source.

  • Publication number: 20180292053
    Abstract: A light source includes a plurality of laser diodes or other light emitters. Beams of light from the light emitters are steered to provide n array of parallel beams that illuminate a target area with an array of patches of light. In some embodiments the parallel beams are de-magnified to form the array of patches of light. Such a light source has application in illuminating dynamically-addressable focusing elements such as phase modulators, deformable mirrors and dynamically addressable lenses. Light projectors for a wide variety of applications may combine a light source as described herein with a dynamically-addressable focusing element to project defined patterns of light.

  • Publication number: 20180270457
    Abstract: A new projector design combines one spatial light modulator that affects only the phase of the illumination, and one spatial light modulator that only affects its amplitude (intensity). The phase-only modulator curves the wavefront of light and acts as a pre-modulator for a conventional amplitude modulator. This approach works with both white light and laser illumination, generating a coarse image representation efficiently, thus enabling, within a single image frame, significantly elevated highlights as well as darker black levels while reducing the overall light source power requirements.
