The intensity distribution of a radiation field imaged on a scintillation crystal of a gamma camera can be quantified by allocating to each elementary area of the crystal a number which represents the number of light flashes which have occurred, according to calculation, within a given period of time in the given elementary area. The resolution of the camera can be improved by the contents of the storage elements being weighted in accordance with probability, by a light flash which has occurred in a given elementary area according to calculation actually having occurred there, so that the weighted contents of the storage element better approximate the actual density distribution of the light flashes than the unweighted contents of the storage element.
