Abstract
To provide an electronic endoscope system provided with an objective optical system for optically magnifying an image to be observed by using a variable power lens and an electronic zoom IC circuit for electronically magnifying an image obtained by a CCD. A depth of field at the time of switching between optical variable power and electronic variable power is set at an arbitrary value by key operation etc. of a control panel of a processor. When the depth of field becomes a setting value, for example, 16 mm (lens position before Near end), during the operation of optical variable power based on the operation of a variable power switch, electronic variable power is executed by the electronic zoom IC circuit. Thereby, an enlarged image in which the depth of a subject to be observed with irregularities is properly in focus can be obtained.
