Document Type and Number:
Japanese Patent JP2018158152
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an endoscope system, processor device, actuation method for the endoscope system, and actuation method for the processor device, capable of extracting and displaying a picture of a target to be observed, a blood vessel existing at a specific depth.SOLUTION: An endoscope system 10 comprises: a picture signal acquisition unit 53 for acquiring a B1 picture signal corresponding to violet light V and a B2 picture signal corresponding to blue light B; a calculation picture signal generation unit 76 for generating a calculation picture signal on a target to be observed, a blood vessel existing at a specific depth, by using the B1 picture signal and the B2 picture signal; a brightness comparison unit 71 for comparing brightness of the B1 picture signal and the B2 picture signal to be used for generating the calculation picture signal; and a control unit 72 that by using a comparison result of the brightness comparison unit 71, makes control for a light source 20 or an imaging sensor 48 in the case of acquiring the B1 picture signal be different from that in the case of acquiring the B2 picture signal so that a ratio of brightness of the B1 picture signal and the B2 picture signal to be used for generating the calculation picture signal becomes a specific ratio.SELECTED DRAWING: Figure 2
