<p>The invention provides an endoscope system, a light source device for an endoscope and a manufacturing method of endoscope images. According to the invention, high-definition general images, blood vessel emphasizing images and oxygen saturation images can be obtained with fewer frames. A rotary filter comprises an open part transmitting broad-band light as original, a measurement filter part transmitting oxygen saturation measuring light of 450-500nm in the broad-band light, and a blood vessel emphasizing filter part transmitting blood vessel emphasizing illuminating light of 405-425nm and 530-550nm in the broad-band light. The area of the measurement filter part and the area of the blood vessel emphasizing filter part are greater than that of the open part. Thus, the illuminating time of the oxygen saturation measuring light and the illuminating time of the blood vessel emphasizing illuminating light become longer than illumination time of the broad-band light.</p> |
