Abstract: Aspects relate to methods of generating a high-resolution image containing object depth information. A method may include capturing a first image of an object using a first camera, the first image including light projected in a known pattern on the object, extracting depth information at a first resolution from the first image, the depth information extracted based on a pattern of the projected light in the first image and capturing a second image of the scene using a second camera, the second image captured at a second resolution which is higher than the first resolution. The method also includes aligning geometries of the first and second image based on a known difference in location of the first camera and the second camera and using the second image to up-sample the depth information from the first resolution to a third resolution, the third resolution is higher than the first resolution.

Abstract: A method for generating codes for a code mask is provided. A plurality of symbols may be arranged into an n1 by n2 symbol structure, where n1 and n2 are integer values. A plurality of codewords may be defined from different overlapping k1 by k2 windows within the symbol structure, wherein co-linear and spatially overlapping windows define unique codewords, and the codewords are unique in a first direction of the symbol structure but are repeated in a second direction that is perpendicular to the first direction. A plurality of the symbol structures as a code mask, wherein symbols in two adjacent k1 by k2 windows are selected so as to avoid codeword aliasing of codewords in the two adjacent k1 by k2 windows.

Abstract: Methods, devices, and computer program products for multi-frame termporal de-noising using image alignment are describe. In one aspect, a method of capturing an image using a multi-frame temporal de-noising is described. The method includes capturing a plurality of frames and aligning the captured plurality of frames with each other. The method further includes determining a subset of frames of the captured plurality of frames, the subset determined based upon a focus quality of each frame of the plurality of frames. Finally, the method includes combining the subset of frames into a single image using a motion filter to reduce blurriness and ghosting.

Abstract: An interactive display, including a cover glass having a front surface that includes a viewing area provides an input/output (I/O) interface for a user of an electronic device. An arrangement includes a processor, a light source, and a camera disposed outside the periphery of the viewing area coplanar with or behind the cover glass. The camera receives scattered light resulting from interaction, with an object, of light outputted from the interactive display, the outputted light being received by the cover glass from the object and directed toward the camera. The processor determines, from image data output by the camera, an azimuthal angle of the object with respect to an optical axis of the camera and/or a distance of the object from the camera.
