Optical sensor devices, image processing devices, methods and computer readable code computer-readable storage media for detecting biophysical parameters, chemical concentrations, chemical saturations, vital signs and physiological information such as a malignant condition are provided. The optical sensor includes an array of photodetectors, where each photodetector is configured to detect a spectrum of light. Exemplary physiological parameters include but are not limited to a pulse rate, a biophysical or physiological property of skin, a cardiovascular property, a property related to an organ such as the liver or the kidneys, and a temperature fluctuation. Alternatively one or more parameters are detected from a food item such as food tissue, a consumable beverage such as an alcoholic beverage, a dairy product, wine, a baked good, a fruit and a vegetable.
