Abstract
The invention relates generally to both a method and apparatus for the creation of full resolution color digital images of diagnostic cassettes or objects of interest using a gray-scale digital camera or sensor combined with time sequential illumination using additive primary colors followed by post exposure digital processing. Such procedures and equipment is of significant economic value when employed in situations such as diagnostic clinical analyzers where space is limited and image quality requirements are high.
Claims13
An apparatus for the construction of a color digital image of an object of interest comprising:
- a gray-scale digital camera or sensor capable of generating a plurality of gray-scale images while the object of interest is illuminated with lights having different wavelengths,
- a mechanical means to hold said object of interest with respect to the gray-scale digital camera or sensor,
- a source of front illumination capable of multiple illuminations of said object of interest with red, green, and blue wavelength light,
- a source of rear illumination capable of multiple illuminations of said object of interest with red, green, and blue wavelength light, and
- a means to construct a color digital image of said object of interest by combining color plane data created from the plurality of gray-scale images viewed by the gray-scale digital camera or sensor, wherein said means is in electrical contact with said gray-scale digital camera or sensor.
