Claim One:
1. An endoscopic system, comprising: an endoscope provided with an objective lens at a tip of an insertion portion to be inserted into a body cavity; an image capturing unit that captures an optical image input from the endoscope and condensed by the objective lens, and that outputs the captured image as an image signal; a low-frequency component extracting unit that extracts a low-frequency image with a frequency component lower than the image signal; a high-frequency component extracting unit that extracts a high-frequency image with a frequency component higher than the image signal; an image quality enhancement processor that applies image quality enhancement processing to the low-frequency image; and an output unit that at least outputs the low-frequency image, whose image quality has been enhanced by the image quality enhancement processor, as an output image, wherein the output unit outputs, as the output image, an image signal including pixel values obtained by adding pixel values of individual pixels of the high-frequency image to pixel values of individual pixels of the low-frequency image, whose image quality has been enhanced, in accordance with condition information upon image capturing performed by the image capturing unit.
