Abstract: The present disclosure relates to curved arrays of individually addressable light-emitting elements for sweeping out angular ranges. One example device includes a curved optical element. The device may also include a curved array of individually addressable light-emitting elements arranged to emit light towards the curved optical element. A curvature of the curved array is substantially concentric to at least a portion of the circumference of the curved optical element. The curved optical element is arranged to focus light emitted from each individually addressable light-emitting element to produce a substantially linear illumination pattern at a different corresponding scan angle within an angular range. The device may further include a control system operable to sequentially activate the individually addressable light-emitting elements such that the substantially linear illumination pattern sweeps out the angular range.

Abstract: A light emitter is provided to emit, into an environment of interest, a plurality of different patterns of light during respective periods of time. Each of the different patterns of light varies according to angle in a first direction such the location of a light detector disposed in the environment can be determined based on illumination from the light emitter that is detected by the light detector over time. The light emitter includes an astigmatic optical element and a die on which are disposed multiple sets of one or more light emitters, each set corresponding to a respective pattern of illumination emitted from the light emitter. Such a configuration of the light emitter can provide means for producing the different patterns of illumination in an energy-efficient, low-cost, and/or size-constrained manner.

Abstract: The present disclosure relates to staggered arrays of individually addressable light-emitting elements for sweeping out angular ranges. One example device includes an astigmatic optical element. The device may also include an array of individually addressable light-emitting elements arranged to emit light towards the astigmatic optical element. The astigmatic optical element may be arranged to focus light emitted from each individually addressable light-emitting element to produce a substantially linear illumination pattern at a different corresponding scan angle within an angular range. The example device may further include a control system operable to sequentially activate the individually addressable light-emitting elements such that the substantially linear illumination pattern sweeps out the angular range. The individually addressable light-emitting elements may be staggered with respect to one another in the array such that the substantially linear illumination pattern sweeps out the angular range continuously.

Abstract: Imaging systems can often gather higher quality information about a field of view than the unaided human eye. For example, telescopes may magnify very distant objects, microscopes may magnify very small objects, and high frame-rate cameras may capture fast motion. The present disclosure includes devices and methods that provide real-time vision enhancement without the delay of replaying from storage media. The disclosed devices and methods may include a live view user interface with two or more interactive features or effects that may be controllable in real-time. Specifically, the disclosed devices and methods may include a live view display and image and other information enhancements, which utilize in-line computation and constant control.

Abstract: Example embodiments may help multi-camera devices determine disparity information scene, and use the disparity information in an autofocus process. An example method involves: (a) receiving image data of a scene that comprises at least one image of the scene captured by each of two or more image-capture systems of a computing device that includes a plurality of image-capture systems; (b) using the image data captured by the two or more image-capture systems as a basis for determining disparity information for the scene; and (c) performing, by the computing system, an autofocus process based at least in part on the disparity information, wherein the autofocus process provides a focus setting for at least one of the image-capture systems of the computing device.

Abstract: The present disclosure relates to methods and systems that may reduce pixel noise due to defective sensor elements in optical imaging systems. Namely, a camera may capture a burst of images with an image sensor while adjusting a focus distance setting of an optical element. For example, the image burst may be captured during an autofocus process. The plurality of images may be averaged or otherwise merged to provide a single, aggregate image frame. Such an aggregate image frame may appear blurry. In such a scenario, “hot” pixels, “dead” pixels, or otherwise defective pixels may be more easily recognized and/or corrected. As an example, a defective pixel may be removed from a target image or otherwise corrected by replacing a value of the defective pixel with an average value of neighboring pixels.
