Abstract: A 3D imaging system comprises a phase detection autofocus (PDAF) image sensor, a lens for imaging a cross-section of a 3D object on the PDAF image sensor and an actuator for driving the lens for focusing each cross-section of the 3D object on the PDAF image sensor. The actuator drives the lens until the PDAF image sensor identifies an image of a first cross-section of the 3D object in-focus and records the image of the first cross-section. The PDAF image sensor records images of subsequent cross-sections of the 3D object formed by the lens driven by the actuator on the PDAF image sensor. The recorded images of each cross-section of the 3D object are stacked to form a 3D image of the 3D object.

Abstract: A display system includes a display positioned to show images to a user, and a sensor positioned to monitor a gaze location of an eye of the user. A controller is coupled to the display and the sensor, and the controller includes logic that causes the display system to perform operations. For example, the controller may receive the gaze location information from the sensor, and determine the gaze location of the eye. First resolution image data is output to the display for a first region in the images. Second resolution image data is output to the display for a second region in the images. And third resolution image data is output to the display for a third region in the images.
