Abstract: An apparatus for touch-sensing includes a light-emitting layer covered by a transparent layer and configured to illuminate a surface touching the transparent layer and to allow transmission of reflected light rays from the surface to underlying layers. The underlying layers include an optical coupling layer, a collimator layer and a pixelated image sensor. The optical coupling layer bends the reflected light rays to create oblique light rays. The collimator layer includes a number of apertures to collimate the received light rays. The pixelated image sensor senses the collimated oblique light rays.

Abstract: Techniques are described that utilize continuous flash lighting, e.g., with automatic activation/deactivation and brightness control of a flash lighting element in an electronic image capturing device. Depth sensing, in combination with front and/or rear lux sensing, is performed at the device and used to evaluate the lighting on the object of interest being captured and/or the overall scene light levels. A lighting element (e.g., a single- or multi-channel flash element) may be controlled automatically based on the depth, front and rear lux sensing, or a combination thereof. The lighting element's intensity may be automatically adjusted in a smooth and gradual manner, e.g., utilizing ranges of acceptable lux values and/or non-linear lighting element activation functions.

Abstract: Methods and apparatus for camera focusing for video passthrough devices. Gaze information from a gaze tracking subsystem, either alone or along with depth information from a depth tracking system, may be leveraged to determine depths at which to focus. Gaze information, or a combination of depth and gaze information, may be used. As an alternative, the user can manually control the focus distance. For example, a manual bifocal method may provide two focus distances (near focus and far focus.

Abstract: A light source module includes an array of illumination elements and an optional projecting lens. The light source module is configured to receive or generate a control signal for adjusting different ones of the illumination elements to control a light field emitted from the light source module. In some embodiments, the light source module is also configured to adjust the projecting lens responsive to objects in an illuminated scene and a field of view of an imaging device. A controller for a light source module may determine a light field pattern based on various parameters including a field of view of an imaging device, an illumination sensitivity model of the imaging device, depth, ambient illumination and reflectivity of objects, configured illumination priorities including ambient preservation, background illumination and direct/indirect lighting balance, and so forth.

Abstract: A device such as a stylus may have a color sensor. The color sensor may have a color sensing light detector having a plurality of photodetectors each of which measures light for a different respective color channel. The color sensor may also have a light emitter. The light emitter may have an adjustable light spectrum. The light spectrum may be adjusted during color sensing measurements using information such as ambient light color measurements made with a color ambient light sensor that has a plurality of photodetectors each of which measures light for a different respective color channel. An inertial measurement unit may be used to measure the angular orientation between the stylus and an external object during color measurements. Arrangements in which the light emitter is modulated during color sensing may also be used. Measurements from the stylus may be transmitted wirelessly to external equipment.

Abstract: Embodiments disclosed herein are directed to devices and methods for performing spatially-varying brightness correction of a flash image. The spatially-varying brightness correction utilizes a set of images that includes one or more images captured under flash illumination and one or more images captured without flash illumination, which are used to decompose one of the flash images or an image generated therefrom into a flash contribution image and an ambient contribution image. The flash contribution image and the ambient contribution image are recombined to generate a corrected flash image, and information about the flash module and/or scene is used to adjust the relative contributions of these images during recombination.
