Abstract
An image rendition and capture method includes rendering a first image on a surface using a first set of wavelength ranges of light. While the first image is being rendered, a second image is captured using a second set of wavelength ranges of light but not the first set. The second image is of the surface on which the first image is being rendered.
Claims18
An image rendition and capture method, comprising:
- a projector rendering a first image on a surface using a first set of wavelength ranges of light;
- and
- a camera capturing, while the first image is being rendered, a second image using a second set of wavelength ranges of light but not the first set, the second image being of the surface on which the first image is being rendered;
- wherein the first set of wavelength ranges represent a first portion of a first color of the color spectrum and wherein the second set of wavelength ranges represent a second portion of the first color of the color spectrum.

An image rendition and capture method, comprising:
- a camera receiving a first image of a first surface on which a first collaborator has formed a first drawing;
- a projector rendering the first image on a second surface using a first set of wavelength ranges of light;
- capturing, while the first image is being rendered a second image using a second set of wavelength ranges of light but not the first set, the second image being of the second surface on which the first image is being rendered and on which a second collaborator has formed a second drawing;
- wherein the first set of wavelength ranges represent a first portion of a first color of the color spectrum and wherein the second set of wavelength ranges represent a second portion of the first color of the color spectrum;
- and
- communicating the second image to be rendered on the first surface.
3 more elements
An image rendition and capture system comprising a camera and a projector, wherein:
- The projector is configured to render a first image on a local surface using a first set of wavelength ranges of light;
- and
- the camera is configured to capture, while the first image is being rendered, a second image using a second set of wavelength ranges of light but not the first set, the second image being of the local surface on which the first image is being rendered;
- wherein the first set of wavelength ranges represent a first portion of a first color of the color spectrum and wherein the second set of wavelength ranges represent a second portion of the first color of the color spectrum.
