摘要： An endoscope system is provided with a light source unit for generating illumination light, an image sensor for imaging an object of interest irradiated with the illumination light, an image signal obtaining section, a calculated image signal generator, and an image generator. The image signal obtaining section obtains a B1 image signal corresponding to violet light and a B2 image signal corresponding to blue light. The calculated image signal generator generates a calculated image signal from the B1 and B2 image signals. The image generator generates an image in which one of the B1 image signal and the B2 image signal is assigned to a luminance channel or a green channel and the calculated image signal is assigned to a remaining channel.

摘要： Provided is a medical image processing system that can stably control the light emission amount of narrow-band light of a short wavelength in a case where the narrow-band light of the short wavelength is used for illumination of an observation target. A light source circuit emits specific narrow-band light of a short wavelength. An image sensor includes a first pixel group including a B pixel and a second pixel group including a G pixel. The B pixel has a higher sensitivity to the specific narrow-band light than the G pixel. The G pixel has a sensitivity to light in a green band and the specific narrow-band light. The light source control unit controls the light emission amount of the specific narrow-band light on the basis of a pixel value of the B pixel and a pixel value of the G pixel.

摘要： Provided are an endoscope system and a method of operating the same capable of reliably performing focusing even in a case where an observation target is illuminated with light including long-wave light. A movable lens moves in an optical axis direction. A lens drive unit moves the movable lens from a first lens position of the movable lens where an observation target illuminated with short-wave light is focused to a second lens position of the movable lens where the observation target illuminated with long-wave light having a longer wavelength than the short-wave light is focused.
