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 spatial light system that may, for example, be used to project image content onto surfaces of a room. The system may include two or more projection units for emitting light onto surfaces within a room. The system may include a controller and two or more projection units, each module including an LED array, an array of light pipes, and a condenser lens. Two or more projection units may be connected to a flexible strip that provides power and data (e.g., serial data) to the projection units. Two or more flex strips may be connected together. The flex strips provide a serially-connected, flexible modular architecture for spatial light systems that allow the projection units to be conformed to a variety of configurations and shapes.

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: Methods and apparatus for generating images to be displayed on lenticular displays. In these methods, a fixed mesh is generated offline, and in real-time texture information is mapped to the fixed mesh. In an offline process, texture and 3D mesh information for an object is used to render UV map views for multiple viewpoints of the object, view maps are generated from display calibration data, and a lenticular to UV map is generated from the UV map views and view maps. In real-time, texture information is captured, and a composite process is performed that generates a lenticular image for multiple viewpoints by sampling pixels from the texture based on the lenticular to UV map. The lenticular image is then displayed on the lenticular display. Detected positions of persons in the environment may be used to limit the number of viewpoints that are generated during the real-time composite process.

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.
