ABSTRACT:
An electronic endoscope system used for observing living tissues inside a body cavity includes a single imaging device configured to output image signals corresponding to a received optical image, an illuminating apparatus having a white light source emitting white light and an excitation light source emitting excitation light, an image forming system configured to form the optical image of the living tissues illuminated with each of the white light and the excitation light on the imaging device, a display device, an image processing system that receives the image signals output from the single imaging device, the image processing system transforming the received image signals into signals which are allowed to be displayed on the display device, and a control system configured to control the whole of the electronic endoscope system, the image processing system employs image signals, obtained from an image, output from the single imaging device as a first field of image signals of an interlaced image, and employs image signals obtained by performing an arithmetical operation for image signals, obtained from a plurality of images, output from the single imaging device as a second field of image signals of the interlaced image.
