1. An endoscope system comprising:
a processor configured to:
control a light source to switch between generating first illumination light and second illumination light;
receive an instruction to switch from a first observation mode in which a first image is obtained by an image pickup sensor based on illumination with the first illumination light to a second observation mode in which a third image is obtained by processing at least one of a color and a pattern of a second image obtained by the image pickup sensor based on illumination with the second illumination light;
calculate a first feature value indicating a first amount of movement of a distal end portion of an endoscope provided with the image pickup sensor based on the first image;
determine whether the first amount of movement of the distal end portion of the endoscope, indicated by the first feature value, before switching from the first observation mode to the second observation mode, is equal to or higher than a first predetermined threshold; and
in response to determining that the first amount of movement before switching from the first observation mode to the second observation mode is equal to or higher than the first predetermined threshold, maintain the first observation mode.
