In an electronic endoscope, and a memory which contains image pickup area information including size and light distribution characteristics are provided, and in a processor device to which this electronic endoscope is connected, a photometric part for measuring the light receiving state by using separated photometric areas, and a microcomputer are provided, and this microcomputer reads the above described image pickup area information on the electronic endoscope side, and sets a photometric areas (EA to EC) whose size is approximately the same corresponding to the size of the image pickup area in the above described photometric part, and in the meantime, gives weightings A to C to each separated area of these photometric areas (EA to EC). Consequently, even in the case where the sizes and the light distribution characteristics of the actual image pickup areas (FA to FC) determined by the objective optical system are changed, it is possible to realize fine photometry and brightness control.
