ABSTRACT:
Disclosed is a range finder system which includes a virtual image type first optical system for observing an object, and a second optical system for electronically capturing image of at least a part of the object. The range finder system is provided with an LCD (liquid crystal display) which displays the image captured by the second optical system. The image displayed on the liquid crystal display is directed to the virtual image type finder optical system, and the image as displayed on the LCD is combined with the image observed through the first optical system. Thus, two images are observed by a photographer as superimposed. A display controller controls the LCD so that the degree of coincidence of the superimposed images is varied in the direction of a base length based on an object distance information.
