Abstract
Configuration image data representing an external form of an object is stored in advance in a configuration image memory. A two-dimensional image of faint light emitted from the object is detected by a high-sensitivity image pickup means including a two-dimensional photon-counting tube. Faint light image data representing the detected faint light image is accumulated by an adder circuit, and stored in a faint light image memory. The stored faint light image data is superposed on the stored configuration data for each accumulating operation, and based on the superposed image data a superposed image is successivley displayed on a display device.
