Abstract: 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.

Abstract: Violet light and green light are mixed and emitted at a first light amount ratio. A contrast difference value ΔC1 of first mixed color light emission between a blood vessel contrast of a blue image of first mixed color light emission and a blood vessel contrast of a green image of first mixed color light emission at a specific blood vessel depth satisfies a first condition, and a cross-point blood vessel depth VD1 of first mixed color light emission corresponding to a cross-point CP1 between the blood vessel contrast of the blue image of the first mixed color light emission and the blood vessel contrast of the green image of the first mixed color light emission satisfies a second condition.

Abstract: Provided is a medical image processing system capable of maintaining or improving the resolution of an image obtained by using narrow-band light of a short wavelength while maintaining image quality of an image obtained by using broadband light such as white light. A light source unit 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 and a W 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 W pixel has a sensitivity to broadband illumination light including the light in the green band and the specific narrow-band light.

Abstract: A processor device and an endoscope system capable of calculating an optimal index value in accordance with a diagnosis purpose is provided. A processor device includes an image acquisition unit, a diagnosis purpose acquisition unit, an index value storage unit, an index value selection unit, and an index value calculation unit. The image acquisition unit acquires an endoscope image obtained by an endoscope image-capturing an observation object. The diagnosis purpose acquisition unit acquires a diagnosis purpose. The index value storage unit stores correspondence between the diagnosis purpose and a plurality of index values relating to a structure of the observation object. The index value selection unit refers to the index value storage unit and selects the index value that is used for the acquired diagnosis purpose. The index value calculation unit uses the endoscope image and calculates the selected index value.

Abstract: 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, and a calculated image signal generator. The image signal obtaining section obtains a B1 image signal corresponding to violet light and a B2 image signal corresponding to blue light that differs in scattering coefficient of the object of interest from the violet light and that has the same absorption coefficient as the violet light. The calculated image signal generator generates a calculated image signal from the B1 and B2 image signals.

Abstract: An endoscope system comprises an LED light source unit, an image sensor, an imaging distance calculator and a light source controller. The LED light source unit generates illumination light. The image sensor has a blue pixel, a green pixel, a red pixel and a specific pixel receiving at least light in a blue wavelength band and a green wavelength light, and images an observation object by reflected light of the illumination light from the observation object. The imaging distance calculator calculates an imaging distance that is a distance between the image sensor and the observation object. The light source controller controls the light source unit to increase a component of the blue wavelength band or the green wavelength band included in the illumination light according to the imaging distance.
