ABSTRACT:
An endoscopic system provides a color picture by combining three primary color images with each other. The endoscopic system comprises an image converting device for performing a process of converting the respective primary color images into hue, saturation, and intensity images, and a process of reproducing three primary color images from the converted hue, saturation, and intensity images; and a histogram processing device for performing a process of obtaining a histogram based on at least one of the hue, saturation, and intensity images obtained by the image converting device, and executing at least one of a process of stretching the histogram and a process of shifting the histogram.
