Abstract
First illumination light having a first peak wavelength range and second illumination light having a second peak wavelength range different from the first peak wavelength range are automatically switched and emitted. Identification processing for allowing a first object to be observed and a second object to be observed to be identified in a composite display image is performed. The first object to be observed has a first absorption peak in the first peak wavelength range of the first illumination light and the second object to be observed has a second absorption peak in the second peak wavelength range of the second illumination light.
Claims12
An endoscope system comprising:
- a light source unit that emits first illumination light having a first peak wavelength range and second illumination light having a second peak wavelength range different from the first peak wavelength range;
- a light source control unit that automatically switches and emits the first illumination light and the second illumination light for a light emission period of at least one or more frames;
- a color image pickup sensor that includes specific pixels provided with specific color filters transmitting light having a wavelength range corresponding to the first peak wavelength range and light having a wavelength range corresponding to the second peak wavelength range;
- an image acquisition unit that acquires first image signals obtained in a case where an image of an object to be observed illuminated with the first illumination light is picked up by the image pickup sensor and second image signals obtained in a case where an image of an object to be observed illuminated with the second illumination light is picked up by the image pickup sensor;
- and
- a composite display image-processing unit that performs identification processing for allowing a first object to be observed and a second object to be observed to be identified in a composite display image in a case where the composite display image-processing unit synthesizes the first image signals and the second image signals to generate the composite display image, the first object to be observed having a first absorption peak in the first peak wavelength range of the first illumination light and the second object to be observed having a second absorption peak in the second peak wavelength range of the second illumination light.
