Abstract: Techniques are disclosed for depth map generation in a structured light system where an optical transmitter is tilted relative to an optical receiver. The optical transmitter has a transmitter optical axis around which structured light spreads, and the optical receiver has a receiver optical axis around which a reflection of the structured light can be captured. The transmitter optical axis and the receiver optical axis intersect one another. A processing circuit compensates for the angle in the tilt in the reflected pattern to generate the depth map.

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.

Abstract: A method for displaying preview images is disclosed. In one aspect, the method includes: receiving first images captured by a first camera having a first field-of-view (FOV), receiving second images captured by a second camera having a second FOV that is different than the first FOV, and displaying preview images generated based on the first and second images. The method may further include determining a spatial transform based on depth information associated with individual pixels in the first and second images, and upon receiving instructions to zoom in or out beyond a camera switching threshold, modifying the second image using the spatial transform and displaying the first image and the modified second image consecutively.
