Abstract
A depth sensing multiple camera system is described that uses depth sensing cameras. In one example, the camera system includes a primary auto-focus camera to capture an image of a scene at a first focus distance, the primary camera having a fixed field of view through different focus distances, a secondary auto-focus camera to capture an image of the same scene at a second focus distance, the secondary camera having a fixed field of view through different focus distances, and a processor having a first port coupled to the primary camera to receive images from the primary camera and a second port to receive images from the secondary camera and to determine a depth map for the captured primary camera image using the captured secondary camera image.
