Abstract

A system and method for implementing integrated and adjustable image projection with auto-image correction in electronic devices using an in-facing or world-facing image projector are disclosed. A particular embodiment includes an electronic device including: a lid; a base including a hinge coupling the lid with the base; and an image projection subsystem including an image projector installed in the lid, the image projector being configured to produce a projected image that is projected onto a projection surface, the angle of the projection being adjustable by adjusting the angle of the lid relative to the base.

First claim

What is claimed is:

1 . An electronic device comprising:
a lid; a base including a hinge coupling the lid with the base; and an image projection subsystem including an image projector installed in the lid, the image projector being configured to produce a projected image that is projected onto a projection surface, the angle of the projection being adjustable by adjusting the angle of the lid relative to the base.

2 . The electronic device as claimed in claim 1 wherein the image projection subsystem is configured to project the projected image in an outwardly-facing or world-facing direction.

3 . The electronic device as claimed in claim 1 wherein the image projection subsystem is configured to project the projected image in an inwardly-facing or user-facing direction.

4 . The electronic device as claimed in claim 1 wherein the image projection subsystem further including a camera to capture at least a portion of the projected image.

5 . The electronic device as claimed in claim 4 further including a processor to analyze the captured image and to cause correction of the projected image based on the analysis of the captured image.

6 . The electronic device as claimed in claim 5 wherein the processor is an image processor of the image projection subsystem.

7 . The electronic device as claimed in claim 5 wherein the processor is a standard data processor of the electronic device.

8 . The electronic device as claimed in claim 5 wherein the correction of the projected image includes controlling a lens element of the image projector to adjust the focus of the projected image.

9 . The electronic device as claimed in claim 5 wherein the correction of the projected image includes modifying the image projected by the image projector by performing at least one of the operations from the group consisting of: auto-focusing, auto-keystoning, auto-color adjustment, and auto-surfacing.

10 . The electronic device as claimed in claim 1 wherein the electronic device is of a type from the group consisting of: a mobile computing device, a mobile communication device, a two-in-one desktop device, an all-in-one desktop device, a laptop computer, an ultrabook computer, a detachable computing device, a handheld computer, a wearable computing platform, a touch screen system, a tablet computing system, a Personal Digital Assistant (PDA), a cellular telephone, a smartphone, and a web appliance.

11 . An image projection subsystem comprising:
an image projector configured to produce a projected image that is projected onto a projection surface; a camera to capture at least a portion of the projected image; and a processor to analyze the captured image and to cause correction of the projected image based on the analysis of the captured image.

12 . The image projection subsystem as claimed in claim 11 wherein the image projection subsystem is configured to project the projected image in an outwardly-facing or world-facing direction.

13 . The image projection subsystem as claimed in claim 11 wherein the image projection subsystem is configured to project the projected image in an inwardly-facing or user-facing direction.

14 . The image projection subsystem as claimed in claim 11 wherein the correction of the projected image includes controlling a lens element of an image projector to adjust the focus of the projected image.

15 . The image projection subsystem as claimed in claim 11 wherein the correction of the projected image includes modifying the projected image by performing at least one of the operations from the group consisting of: auto-focusing, auto-keystoning, auto-color adjustment, and auto-surfacing.

16 . A method comprising:
providing an electronic device having a lid and a base, the base including a hinge coupling the lid with the base; providing an image projection subsystem including an image projector in the lid of the electronic device, the image projector being configured to produce a projected image that is projected onto a projection surface; projecting the projected image onto the projection surface; and adjusting the angle of the projection by adjusting the angle of the lid relative to the base.

17 . The method as claimed in claim 16 further including capturing at least a portion of the projected image, analyzing the captured image, and causing correction of the projected image based on the analysis of the captured image.

18 . The method as claimed in claim 16 wherein the correction of the projected image includes modifying the image projected by the image projector by performing at least one of the operations from the group consisting of: auto-focusing, auto-keystoning, auto-color adjustment, and auto-surfacing.

19 . An apparatus comprising:
a lid means; a base means including a hinging means coupling the lid means with the base means; and an image projection means installed in the lid means, the image projection means being configured to produce a projected image that is projected onto a projection surface, the angle of the projection being adjustable by adjusting the angle of the lid means relative to the base means.

20 . The apparatus as claimed in claim 19 wherein the image projection means further including an image capture means to capture at least a portion of the projected image.
