Image marking method and apparatus
First Claim
Patent Images
1. A method for marking a first image projected to a surface, comprising:
- capturing, by an image capturing component of an image device, a second image from the surface;
detecting a marking point in the second image, wherein the marking point is generated by a marking device, placed on a viewing path between the image capturing component and the surface, emitting light toward the image capturing component; and
generating a third image by placing a graphic element in the first image at a location corresponding to a location of the marking point in the second image.

12. A method for marking a first image projected to a surface, comprising:
-
capturing a second image from the surface; detecting a marking point in the second image, the marking point being associated with a difference detected by comparing the first image and the second image; determining a location of the marking point in the second image; modifying the first image to generate a third image by placing a graphic element at a location corresponding to the location of the marking point in the second image; and projecting the third image to the surface to replace the first image. - View Dependent Claims (13, 14, 15)

16. A system configured to mark an image, comprising:
-
an image projecting component configured to project a first image to a surface; an image capturing component configured to capture a second image from the surface; and an image processor coupled with the image projecting component part and the image capturing component, wherein the image processor is configured to detect a marking point in the second image and to modify the first image to generate a third image by adding a graphic element at a location corresponding to a location of the marking point in the second image, the marking point being associated with a difference detected by comparing the first image and the second image. - View Dependent Claims (17, 18, 19, 20)
