Abstract
Abstract An apparatus for illuminating and imaging a surface includes a two-dimensional array of LEDs for providing uniform illumination to the surface, the LEDs being mounted on a planar surface with a centrally defined aperture, and a CCD-based camera with appropriate lensing for obtaining an image of the illuminated surface and providing a signal representative of that obtained image to a processing unit, the CCD-based camera lensing being disposed through the centrally defined aperture in the planar surface of the LED array, and the LED array and CCD-camera lensing being disposed inside an opaque shroud.

Claim 2
Dependent Claim
75 words
An illumination and imaging apparatus, comprising: (a) a two-dimensional array of LEDs for illuminating a surface; (b) means for obtaining an image of the illuminated surface and providing an output signal representative of said obtained image; and (c) a handle, said LED array and said image obtaining means being mounted on said handle for positioning by hand; wherein said array is supported on a planar surface, an aperture being defined centrally through said planar surface.
Claim 3
Dependent Claim
14 words
The apparatus of claim 1, wherein said image obtaining means is a CCD-based camera.
Claim 4
Dependent Claim
28 words

The apparatus of claim 4, wherein each said horizontal row is offset by half the center-to-center spacing of said LEDs in the preceding and succeeding horizontal rows.
Claim 7
Dependent Claim
71 words
An illumination and imaging apparatus, comprising: (a) a two-dimensional array of LEDs for illuminating a surface; (b) means for obtaining an image of the illuminated surface and providing an output signal representative of said obtained image, said image obtaining means comprising lensing; (c) a generally sleeve-like shroud having a generally vertical opaque wall, defining a lower opening; said array and said lensing being mounted inside an upper portion of said shroud.
Claim 8
Dependent Claim
71 words
An illumination and imaging apparatus, comprising: (a) a two-dimensional array of LEDs for illuminating a surface; (b) means for obtaining an image of the illuminated surface and providing an output signal representative of said obtained image, said image obtaining means comprising lensing; (c) a generally sleeve-like shroud having a generally vertical opaque wall, defining a lower opening; said array and said lensing being mounted inside an upper portion of said shroud.
