  • Patent number: 10381805
    Abstract: The present disclosure provides a VCSEL regular lattice-based laser speckle projector, comprising a VCSEL regular light-emitting lattice, a collimator, a diffractive optical element, an X-Y direction driving circuit, and a lattice display control module; multiple frames of different coded patterns are outputted by driving the light-emitting particles on the VCSEL regular light-emitting lattice to thereby implement a time-space labeling to the target object or projection space, and finally three-dimensional depth measurement of the target object is implemented through a depth decoding algorithm. Compared with the traditional structured-light space coding technology, the projector of the present disclosure facilitates implementation of time-space coding, such that a higher precision, robustness, and antijamming capability may be achieved during the process of depth decoding for the three-dimensional measurement.

  • Patent number: 10345685
    Abstract: An image processing device includes a resolution reducer, a detector, and a corrector. The resolution reducer generates, from an input image, low resolution images for pixel shift display being lower in resolution than the input image. The detector detects portions of the low resolution images corresponding to a specific pattern in which image quality degradation may occur. The corrector performs specific correction processing to reduce the image quality degradation on the portions of the low resolution images corresponding to the specific pattern.

  • Patent number: 10175490
    Abstract: Exemplary light control devices and methods provide a regional variation of visual information and sampling (“V-VIS”) of an ocular field of view that improves or stabilizes vision, ameliorates a visual symptom, reduces the rate of vision loss, or reduces the progression of an ophthalmic or neurologic condition, disease, injury or disorder. The V-VIS devices and methods may optically move, at a sampling rate between 50 hertz and 50 kilohertz, one or more apertures anterior to a retina between one or more positions anterior to the retina that are non-coaxial with a center of a pupil and a position anterior to the retina that is coaxial with the center of the pupil. Certain of these V-VIS devices and methods may be combined with augmented or virtual reality, vision measurement, vision monitoring, or other therapies including, but not limited to, pharmacological, gene, retinal replacement and stem cell therapies.
