Abstract

An apparatus, system, and method for a projection device having a camera to provide for adjustments based at least in part on a series of captured images are disclosed herein.

Claims (21)

1. An apparatus comprising:

a projection arrangement to project one or more images onto a viewing surface;

an image capture device to capture a series of images of the viewing surface and the one or more projected images;

an adjustment mechanism coupled to the projection arrangement; and

a controller coupled to the projection arrangement, the image capture device, and the adjustment mechanism and configured to detect a viewing obstruction in at least a first captured image of the captured series of images, and to control the adjustment mechanism to provide a first one of one or more iterative adjustments to the projection arrangement based at least in part on said detection of the viewing obstruction.

2. The apparatus of claim 1 , wherein the controller is to control the adjustment mechanism to provide the one or more iterative adjustments prior to a subsequent projection of one or more images for viewing.

3. The apparatus of claim 1 , wherein said controller is further configured to control the adjustment mechanism to provide the first one of the one or more iterative adjustments to the projection arrangement by providing for at least one adjustment to a zoom or projection direction of the projection arrangement.

4. The apparatus of claim 1 , wherein the controller is further configured to determine an approximate location of the viewing obstruction, and to control the adjustment mechanism to provide the first one of the one or more iterative adjustments based at least in part on said determination of the approximate location.

5. The apparatus of claim 4 , wherein the controller is further configured to control the adjustment mechanism to provide the first one of the one or more iterative adjustments to the projection direction and a second one of the one or more iterative adjustments to the zoom.

6. The apparatus of claim 1 , wherein the controller is further configured to detect an unobstructed viewing area in at least the first captured image of the captured series of images, and to control the adjustment mechanism to provide the first one of the one or more iterative adjustments to the projection arrangement based at least in part on said detection of the unobstructed viewing area.

7. The apparatus of claim 1 , wherein said image capture device comprises a charge coupled device and/or a complementary metal-oxide semiconductor device.

8. A system comprising:

a source unit configured to output a source signal;

a projection device coupled to the source unit and having

a projection arrangement to project one or more images onto a viewing surface;

an image capture device to capture a series of images of the viewing surface and the one or more projected images;

an adjustment mechanism coupled to the projection arrangement; and a controller coupled to the projection arrangement, image capture device, and the adjustment mechanism and configured to detect a viewing obstruction in at least a first captured image of the captured series of images, and to control the adjustment mechanism to provide a first one of one or more iterative adjustments to the projection arrangement based at least in part on said detection of the viewing obstruction; and

the projection arrangement to project a source image, based at least in part on the source signal, onto the viewing surface.

9. The system of claim 8 , wherein the controller is to control the adjustment mechanism to provide the one or more iterative adjustments prior to a time when the projection arrangement is to project the source image onto the viewing surface.

10. The system of claim 8 , wherein said controller is further configured to control the adjustment mechanism to provide the first one of the one or more iterative adjustments to the projection arrangement, by providing an adjustment to a zoom or projection direction of the projection arrangement.

11. The system of claim 8 , wherein the source unit is a unit selected from the group consisting of a digital versatile disk player, a computing device, and a set-top box.
