True color night vision (TCNV) fusion
First Claim
Patent Images
1. A method of producing an image, comprising:
- obtaining a first image data from a color imaging device;
obtaining a second image data from an infrared imaging device;
separating chroma data and luma data associated with the first image data;
processing luma data associated with the second image data to produce edge data;
combining the luma data associated with the first image data, the luma data associated with the second image and the edge data to produce a combined luma data; and
fusing the combined luma data with the chroma data to obtain a true color image.

Abstract
True color images are produced by combining data collected from one or more color cameras with data collected from one or more infrared cameras. The produced images are the result of combining portions of the visible light data with portions of the infrared light data that may have been captured at dark, at daytime or at low light level conditions. These images appear as normal color images, with infrared information highlighted in a non-distracting fashion. The true color images that are produced in this fashion can also facilitate identification and reproduction of various objects that may not be visible or readily identifiable in infrared or false color imagery.

17. A system, comprising:
-
a color imaging device configured to produce a first image data; an infrared imaging device configured to produce a second image data; and a processor configured to separate chroma data and luma data associated with the first image data, process luma data associated with the second image data to produce edge data, combine the luma data associated the first image data, the luma data associated with the second image data, and the edge data to produce a combined luma data, and fuse the combined luma data with the chroma data to produce a true color image. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
