1. A method for evaluating dispensation of a fluidic substance in an automated analysis instrument, the method comprising:
capturing, using an image capturing device, an image of at least a portion of a fluid receptacle;
obtaining color components of a fragment of the image;
generating a comparison value based on the color components of the fragment of the image; and
performing a comparison of the comparison value and a threshold; and
determining whether to generate a flag for the fluid receptacle based on the comparison of the comparison value and the threshold;
wherein:
the method comprises, for each of a plurality of fragments of the image:
obtaining color components of that fragment of the image; and
generating a comparison value for that fragment based on the color components of that fragment of the image;
the method comprises performing a set of comparisons by, for each of the plurality of fragments of the image, performing a comparison of the comparison value for that fragment and the threshold;
determining whether to generate the flag for the fluid receptacle based on the comparison of the comparison value and the threshold comprises determining whether to generate the flag for the fluid receptacle based on each comparison from the set of comparisons;
wherein determining whether to generate the flag for the fluid receptacle based on each comparison from the set of comparisons comprises determining whether a number of comparison values exceeds a second threshold.
