Abstract: A pass-through camera in a head-mounted device may capture image data for displaying on a display in the head-mounted device. However, only low-resolution image data may be needed to display low-resolution images in the periphery of the user's field of view on the display. Therefore, the pass-through camera may only capture high-resolution images that correspond to the portion of the user's field-of-view that is being directly viewed and may capture lower resolution image data that corresponds to the real-world objects in the user's peripheral vision. To enable the camera module to selectively capture high-resolution images, the pass-through camera may include an image sensor with two or more pixel densities, a distortion lens, and/or one or more planar or curved mirrors. Any of the components in the camera module may be adjusted to change which portion of a scene is captured with high-resolution image data.

Abstract: Depth determination includes obtaining a first image of a scene captured by a camera at a first position, obtaining a second image of the scene captured by the camera at a second position directed by an optical image stabilization (OIS) actuator, determining a virtual baseline between the camera at the first position and the second position, and determining a depth of the scene based on the first image, the second image, and the virtual baseline.

Abstract: Various embodiments disclosed herein include optical aberration control for a camera system. Such a camera system may implement optical aberration control, e.g., by combining one or more variable focus devices with one or more actuators (e.g., a voice coil motor actuator) for moving a lens stack of the camera system to provide autofocus (AF) and/or optical image stabilization (OIS) functionality. A variable focus device may have variable optical power to achieve AF, OIS, and/or introduce optical aberrations such as spherical aberration. In some implementations, the variable focus device may be driven to introduce optical aberrations, and the actuator for moving the lens stack may be driven to compensate for the optical power from the variable focus device.

Abstract: A small format factor camera system for mobile devices that provides improved image quality when using accessory lenses. The system may detect an accessory lens attached to the camera, either via sensing technology or by analyzing captured images. The system may analyze image data to determine current alignment (e.g., optical axis alignment, spacing, and/or tilt) of the accessory lens relative to the camera lens, and may shift the camera lens on one or more axes using a mechanical or optical actuator, for example to align the camera lens optical axis with the accessory lens optical axis. The system may also determine optical characteristics of the accessory lens, either via sensing technology or by analyzing captured images, and may apply one or more image processing functions to images captured using the accessory lens according to the determined optical characteristics of the accessory lens.

Abstract: Camera calibration includes capturing a first image of an object by a first camera, determining spatial parameters between the first camera and the object using the first image, obtaining a first estimate for an optical center, iteratively calculating a best set of optical characteristics and test setup parameters based on the first estimate for the optical center until the difference in a most recent calculated set of optical characteristics and previously calculated set of optical characteristics satisfies a predetermined threshold, and calibrating the first camera based on the best set of optical characteristics. Multi-camera system calibration may include calibrating, based on a detected misalignment of features in multiple images, the multi-camera system using a context of the multi-camera system and one or more prior stored contexts.

Abstract: A pseudo-three dimensional image may be created from a two dimensional image by segmenting the two dimensional image, adjusting the scale of individual segments of the two dimensional image, then superimposing the scaled segment as layers of the pseudo-three dimensional image. By detecting changes in relative orientation of an observer and a programmable device displaying the pseudo-three dimensional image, then translating the scaled segments according to the orientation change, parallax effects may be simulated, enhancing the view of the pseudo-three dimensional image.

Abstract: Systems and methods for providing spatially dynamic illumination in camera systems. A spatially dynamic illumination source enables the illumination of only desired objects in the field of view of the camera, thereby reducing the amount of light required from the illumination source. The spatially dynamic illumination source may include an array of illumination elements and a control component. Each illumination element in the illumination array may include a light-emitting element combined with an optical element. A camera and the spatially dynamic illumination source may be combined in a camera and illumination system. The camera and illumination system may dynamically detect, track, and selectively illuminate only desired objects in the camera field of view.
