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.
Claims20
An imaging device comprising:
- 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.
An apparatus comprising:
- a first means for capturing an image of a scene at a first focus distance, the first image capturing means having a fixed field of view through different focus distances;
- a second means for capturing an image of the same scene at a second focus distance, the second image capturing means having a fixed field of view through different focus distances;
- and
- means for processing having a first port coupled to the primary camera to receive images from the first image capturing means and a second port to receive images from the second image capturing means to determine a depth map for an image from the first image capturing means using an image from the second image capturing means.
A portable device comprising:
- a display on a first surface of the device;
- a user interface;
- a primary auto-focus camera on a second surface of the device opposite the first surface 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 on the second surface of the device 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.
