Most digital memories and TV frame stores used for electron microscopy use analog arithmetic processors to obtain sums, differences and quotients in realtime. These processors can be digital, but the question of using logical arithmetic functions on different images has not been addressed. In order to do so, logical arithmetic operations on electron microscope images can be obtained using a digital frame store device. The logical operations that can be performed are exclusive-ORing (XOR), ORing, and ANDing of images. Since these are Boolean functions, images are not added and hence many of the rescaling problems associated with additions and subtractions in accordance with prior techniques are avoided.
