Abstract

An electronic endoscope processor for processing an image signal of a subject imaged using an imaging element in an electronic endoscope system includes: an illuminating light switch that alternatingly switches the illuminating light to be emitted to the subject, between a first illuminating light and a second illuminating light; and an imaging element control circuit that controls an exposure time of the imaging element and a charge readout timing. The imaging element control circuit controls the exposure time Tof the imaging element when the first illuminating light is being emitted to the subject and the exposure time Tof the imaging element when the second illuminating light is being emitted to the subject, based on a time-integrated amount of luminous flux per unit time of the first illuminating light and a time-integrated amount of luminous flux per unit time of the second illuminating light.
