Abstract
Abstract A camera generates a textured range image. The camera includes a single lens, and a flash substantially co-located with the lens. The camera acquires a first image of a scene from a point of view with ambient light, and a second image of the scene from the point of view with direct light of the flash. The first image and the seconds image are then combined by a divider to generate the textured range image.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
94 words
A camera for generating a textured range image, comprising: a single lens; a flash substantially co-located with the lens; means for acquiring a first image of a scene from a point of view with ambient light using the single lens; means for acquiring a second image of the scene from the point of view with direct light of the flash using the single lens; and means for dividing a luminance of each pixel of the first image by a luminance of a corresponding pixel in the second image to generate the textured range image.
Claim 2
Dependent Claim
94 words
A camera for generating a textured range image, comprising: a single lens; a flash substantially co-located with the lens; means for acquiring a first image of a scene from a point of view with ambient light using the single lens; means for acquiring a second image of the scene from the point of view with direct light of the flash using the single lens; and means for dividing a luminance of each pixel of the first image by a luminance of a corresponding pixel in the second image to generate the textured range image.
Claim 3
Dependent Claim
25 words
The camera of claim 1 further comprising: means for acquiring pairs of first and second images in a sequence to generate a 3D textured video.
Claim 4
Independent Claim
75 words
A method for generating a textured range image, comprising: acquiring, using a single lens, a first image of a scene from a point of view with ambient light; acquiring, using the single lens, a second image of the scene from the point of view with direct light; and dividing a luminance of each pixel of the first image by a luminance of a corresponding pixel in the second image to generate the textured range image.
Claim 5
Independent Claim
75 words
A method for generating a textured range image, comprising: acquiring, using a single lens, a first image of a scene from a point of view with ambient light; acquiring, using the single lens, a second image of the scene from the point of view with direct light; and dividing a luminance of each pixel of the first image by a luminance of a corresponding pixel in the second image to generate the textured range image.
