摘要： 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.

摘要： An image data processor comprising an image signal receiver, a histogram generator, a gain calculator, an amplifier, and a signal feeder, is provided. The image signal receiver receives an autofluorescence image signal. The autofluorescence image signal is generated by an imaging device when the imaging device captures an autofluorescence image. The histogram generator generates a histogram of luminance in the autofluorescence image based on the autofluorescence image signal. The gain calculator calculates a gain based on the histogram and a predetermined luminance value. The amplifier amplifies the autofluorescence image signal by the gain. And then the amplifier generates an amplified autofluorescence image signal. The signal feeder outputs the amplified autofluorescence image signal to a monitor. The monitor displays an amplified autofluorescence image.
