  • Patent number: 10283543
    Abstract: An image sensor may include an array of imaging pixels. Each imaging pixel may have a photosensitive area that is covered by a respective diffractive lens to focus light onto the photosensitive area. The diffractive lenses may have a higher index of refraction than the surrounding materials. The diffractive lenses may be formed on an upper or lower surface of a planarization layer or may be embedded within the planarization layer. In some cases, multiple diffractive lenses may be formed over the imaging pixels. Some of the multiple diffractive lenses may have refractive indexes lower than the planarization layer such that the diffractive lenses defocus light. Focusing and defocusing diffractive lenses may be used to tune the response of the imaging pixels to incident light.

  • Patent number: 10269279
    Abstract: A display system includes one or more multi-view (MV) pixels, each configured to emit beamlets in different directions in a beamlet coordinate system. The display system includes an input node which receives a specification of multiple viewing zones located relative to the MV pixels in a viewing zone coordinate system, and a processor coupled to the input node. The processor associates multiple contents with the multiple viewing zones, respectively, and determines a mapping that translates between the viewing zone coordinate system and the beamlet coordinate system. For each of multiple images generated from the multiple contents, the processor, using the mapping, identifies a bundle of beamlets from each of the MV pixels directed to one viewing zone to form the image. The processor outputs control signaling that defines color and brightness of each of the beamlets in each bundle to project the corresponding image to the corresponding viewing zone.

  • Patent number: 9420220
    Abstract: A method and device are provided for time-sequential recording of three-dimensional images each of which has at least one first and one second partial image. The device has a sensor (13) with pixels (16) subdivided into two mutually different pixel groups. An imaging optical unit has a switchable changeover device (9) that images the partial images of the three-dimensional image time-sequentially onto the sensor (13). A control unit is connected to the sensor (13) and the changeover device (9) to control the reading of the sensor (13) and the switching states of the changeover device (9) so that the changeover device (9), during the imaging of the partial images onto the sensor (13) assumes at least one switching state in which excerpts of different partial images are fed to the different pixel groups of the sensor (13).

  • Patent number: 9245064
    Abstract: Systems, methods, and design software allow for easy and efficient rendering, displaying, navigation, and/or sharing of computer generated designs and models. One or more implementations allow a user to share the geometry and the graphical attributes of a three-dimensional model without sharing the source file or the proprietary details of the source file. In particular, the one or more implementations provide the ability to capture the geometry and the graphical attributes of a three-dimensional model, and share then captured geometry with others. Furthermore, one or more implementations can allow for sharing of the geometry and graphical attributes of a three-dimensional model without requiring the viewer to have the software used to create the three-dimensional model.
