A superimposed display device that superimposes indicators upon an image seen in the viewfinder includes a display that displays multiple displays in fields superimposed upon the image of the viewfinder, a detector that detects the brightness intensity of the fields, and a controller that controls the brightness of the displays and the brightness intensity information concerning a field obtained by the detector. The superimposed indicators are displayed at several locations and by application of both a phased constant drive and brightness modulation, thereby enabling superimposed indicators to be displayed with a wide dynamic range capable of keeping track of an object possessing a brightness pattern.
