15. An operation method for an endoscope system including an endoscope that includes an image pick-up sensor, a light source that irradiates a subject with each of a plurality of pieces of illumination light having different spectra, and a processor device that includes a processor, the operation method comprising:
causing the processor in a first observation mode to execute:
a step of controlling the light source such that the subject is irradiated with each of the plurality of pieces of illumination light in a preset order;
a step of controlling the image pick-up sensor such that the subject is imaged according to a preset first imaging frame rate during a first period in which first illumination light included in the plurality of pieces of illumination light is applied;
a step of acquiring a first image captured by the image pick-up sensor during the first period;
a step of generating an interpolation frame in which the first image is changed, by performing frame interpolation on the basis of the first image;
a step of generating a first display image according to a first display frame rate higher than the first imaging frame rate, by performing frame interpolation on the basis of the first image by combining the first image and the interpolation frame, wherein in the first display image, the interpolation frame is disposed between two of the first images in a time series; and
a step of performing control for displaying the first display image on a display.
