A device for detecting a difference in illumination may include at least two adjacent photoelectric sensor element groups on which light falls during an adjustable illumination time, said light being converted to a quantity of electric charge, which corresponds to the quantity of light falling on each sensor element group during the illumination time, and having a detector, which detects a minimum charge of the charge quantities generated by both photoelectric sensor element groups and subtracts said minimum charge from both photoelectric sensor element groups. The device can be used in a variety of applications, e.g., for digital cameras and medical devices. Wavelet coefficients can be generated directly using metrological and sensory means and may be available for further signal processing. |
