Abstract: An endoscope apparatus includes an illuminating device and a processor. The illuminating device emits display illumination light and support illumination light in a time-division manner. The processor generates a display image based on an image signal acquired when the display illumination light is emitted, and support information based on an image signal acquired when the support illumination light is emitted. The processor generates first support information when an illumination property is a first illumination property, superimposes first display content based on the first support information on the display image, switches the illumination property of the support illumination light to a second illumination property upon determination that the first support information satisfies a predetermined condition, generates second support information when the illumination property is the second illumination property, and superimposes second display content based on the second support information on the display image.
