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.

1-10. (canceled)
A method of constructing a monochrome digital image of an object of interest comprising:
- optically obtaining a red, green, and blue color plane of image data using a grayscale digital camera or sensor;
- selecting one color plane for subsequent manipulation;
- multiplying, element by element, said selected color plane by a pre-defined color weighting matrix producing a weighted selected color plane;
- and
- multiplying said weighted selected color plane by a pre-defined selected gain scalar producing a final selected color plane which is said constructed monochrome digital image.
A method of determining the presence or absence of an agglutination reaction in an imaged diagnostic cassette or object of interest using a combination of at least two of a red, green, or blue monochrome digital image.
