  • Publication number: 20230349536
    Abstract: A high bay light fixture with a monolithic die cast housing. An LED driver and a sensor socket can be installed in a component tray in the center section. The left section and the right section of the housing have LED channels in which LED assemblies are mounted. Lenses can be slid into the LED channels via the open ends of the LED channels. Channel caps are attached to the open ends. Closed ends can also be formed into the housing. The channel caps and the closed ends prevent the lenses from sliding out of the LED channel. Lens tabs prevent the lens from falling out of the LED channels. The housings have bonding bracket mount points and can be attached end to end by bonding brackets attached to the bonding bracket mount points, thereby forming dual and triple fixtures.

  • Patent number: 11792535
    Abstract: A system and method are provided to improve quality in an under-display camera (UDC) system with radially-increasing distortion. At least one processor receives an image and performs multi-frame processing, image signal processing, and a point spread function inversion (PSFI) on the image to produce a processed image. A PSFI radial coring is applied on the processed image to reduce noise in the processed image resulting from the PSFI. The at least one processor can apply a chroma suppression to the processing of the image to reduce brightness and color saturation is select areas in the processed image. Image restoration can be performed on the processed image to produce an output image.

  • Patent number: 11727540
    Abstract: Various image sharpening techniques are disclosed. For example, a method for image sharpening includes obtaining, using at least one sensor of an electronic device, an image that includes visual content. The method also includes generating an edge map that indicates edges of the visual content within the image. The method further includes applying a high-pass signal and an adaptive gain based on the edge map to sharpen the image. The method also includes generating a bright halo mask and a dark halo mask based on the edge map, where the bright halo mask indicates an upper sharpening limit and the dark halo mask indicates a lower sharpening limit. In addition, the method includes modifying a level of sharpening at one or more of the edges within the sharpened image to provide halo artifact reduction based on the bright halo mask and the dark halo mask.
