Patent attributes
An electronic endoscope system according to the present invention has a video-scope that has an image sensor, and a light source unit that is capable of selectively emitting normal-light and excitation-light. The electronic endoscope system further has a signal processor and a display processor. The signal processor generates normal color image signals, which corresponds to the normal color image, on the basis of the normal image-pixel signals. Similarly, the signal processor generates auto-fluorescent image signals corresponding to the auto-fluorescent image on the basis of the auto-fluorescent image-pixel signals, and generates diagnosis color image signals corresponding to the diagnosis color image on the basis of the normal color image signals and the auto-fluorescent image signals. The display processor processes the normal color image signals, the auto-fluorescent image signals, and the diagnosis color image signals so as simultaneously to display a normal color movie-image, an auto-fluorescent movie-image, and a diagnosis color movie-image.
