There is provided a confocal endoscope system which is provided with an electronic endoscope having a confocal optical unit configured to emit illumination light toward an object and to obtain only light from a certain point of the object, and a processor to which the light obtained by the confocal optical unit is inputted. The processor is provided with an image processing unit that generates image data representing an image of the object based on the light transmitted from the confocal optical unit, and a measuring information superimposing unit that generates composite image data representing a composite image generated by superimposing measuring information for measuring the object on the image generated by the image processing unit. The measuring information superimposing unit determines a display condition of the measuring information on the composite image in accordance with an imaging area of the confocal optical unit.
