Abstract: An image sensor including a planar sensor array, a lens configured to form an optical image on the planar sensor array and characterized by a locus of focal points on a curved surface, and a cover glass with multiple thickness levels or multiple cover glasses of different sizes. The one or more cover glasses are configured to shift the locus of focal points for large field angles, such that there are multiple intersections between the planar sensor array and the locus of focal points for a large FOV, and thus multiple zones with best focus on the planar sensor array.

Abstract: Systems, methods, and non-transitory media are provided for low-power visual tracking systems. An example method can include receiving one or more images captured by each image sensor system from a set of image sensor systems on a first device, the one or more images capturing a set of patterns on a second device, wherein the first device has lower power requirements than the second device, the set of patterns having a predetermined configuration on the second device; determining, from the one or more images captured by each image sensor system, a set of pixels corresponding to the set of patterns on the second device; determining, based on the set of pixels corresponding to the set of patterns, a location and relative pose in space of each pattern; and determining, based on the location and relative pose of each pattern, a pose of the first device relative to the second device.

Abstract: An image sensor device includes two or more image sensor arrays (or two or more regions of an image sensor array) and a low-power processor in a same package for capturing two or more images of an object, such as an eye of a user, using light in two or more wavelength bands, such as visible band, near-infrared band, and short-wave infrared band. The image sensor device includes one or more lens assemblies and/or a beam splitter for forming an image of the object on each of the two or more image sensor arrays. The image sensor device also includes one or more filters configured to select light from multiple wavelength bands for imaging by the respective image sensor arrays.

Abstract: In some aspects, a device may detect that an object is contacting a display of the device. The device may illuminate, based at least in part on detecting that the object is contacting the display, a plurality of pixel regions of the display. The plurality of pixel regions may be illuminated sequentially. The device may obtain, using one or more photosensors, a set of data relating to light that is reflected from at least a portion of the object based at least in part on illuminating the plurality of pixel regions. The set of data may include respective data for each sequential illumination of the plurality of pixel regions. The device may generate an image of at least the portion of the object based at least in part on the set of data. Numerous other aspects are described.
