Abstract: A scene camera system that includes two or more mirrors that reflect light from a respective portion of a field of view (FOV) in front of the system and two or more cameras that each capture the light reflected by a respective one of the two or more mirrors. By using the mirrors to reflect the light, the cameras' entrance pupils are imaged to a location closer to a user's eyes to thus achieve a more accurate representation of the perspective of the user.

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: 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.
