Abstract
A method for evaluating the suitability of a mobile device having a camera for performing an analytical measurement based on a color formation reaction. A mobile device is provided and is used to take an image of a reference color field of an object. A color coordinate of pixels of a region of interest within the image is determined and a histogram analysis is performed on a distribution of the color coordinates of the pixels. The width of a color peak within the distribution from the histogram analysis is ascertained and compared with a threshold value to thereby determine suitability of the mobile device for performing the analytical measurement based on the color formation reaction.
