A gamma ray camera A includes a crystal array S which includes a plurality of pixelseach of which outputs a pixel signal in response to receiving a gamma ray. A first circuit (and) outputs for each pixelof the crystal array S, when a pixel signal output by the pixelhas a predetermined relation to a reference signal, a threshold signal related to the position of the pixelin the crystal array S. A second circuit (and) outputs a counter value for each pixel signal having a predetermined relation to its threshold signal. Lastly, a third circuitaccumulates for each pixelof the crystal array S a count of the counter values output by the second circuit (and) for the pixel
