    摘要: Provided is a technology capable of generating and presenting more kinds of special light images with higher image quality. An endoscope system according to the present disclosure performs image processing using a G1 image data (image data obtained by irradiating light of 524±3 nm to 582±3 nm) and at least one of R1 image (image data obtained by irradiating light of 630±3 nm to 700±3 nm) data other than the G1 image data, B1 image data (452±3 nm to 502±3 nm), R2 image data (image data obtained by irradiating light of 582±3 nm to 630±3 nm), G2 image data (image data obtained by irradiating light of 502±3 nm to 524±3 nm), and B2 image data (image data obtained by irradiating light of 420±3 nm to 452±3 nm) so as to generate a special light image (FIG. 7).

    摘要: An endoscope camera head 6 includes a first and a second members 8, 9 that are relatively rotatable about a first axis Ax1. The first member 8 has a first rotation-sliding surface 84 that extends in an annular shape about the first axis Ax1 as its center. The second member 9 has a second rotation-sliding surface 93 that engages with the first rotation-sliding surface 84 in a state in which movement to a direction of the first axis Ax1 relative to the first member 8 is restricted, and that rotation-slides relative to the first rotation-sliding surface 84 about the first axis Ax1. The second rotation-sliding surface 93 abuts only on a part of the first rotation-sliding surface 84, to expose a part of the first rotation-sliding surface 84 outside.

    摘要: An endoscope system includes a light source apparatus to generate an illumination light including a first light in a red to near infrared region, a second light in a green region, and a third light in a blue region, an image pickup device to pick up an image of an object and output an image pickup signal, and a processor to generate a first to third color components corresponding to the first to third lights based on an image generated according to the image pickup signal. The processor generates two of three color components that are blue, green, and red included in an observation image by using a second color component, and generates one remaining color component by using a first color component, and generates respective color components of red, green, and blue included in a white light observation image by using the first to third color components.
