Abstract
Systems and methods for analyzing visible chemical reactions are provided. In one implementation, the method may include receiving from an image sensor associated with a mobile communications device an image of a reagent pad in proximity to a colorized surface having at least one pair of colored reference elements. The method includes identifying in the image the reagent pad, a first colored reference element, and a second colored reference element. Thereafter, the method includes using the first colored reference element and the second colored reference element to determine an extent of a chemical reaction on the reagent pad irrespective of local illumination conditions. Then the method includes causing the mobile communications device to provide data based on the extent of the chemical reaction.
