Abstract: Before an observation region of the imaging optical system reaches an observation position in a culture container, a vertical position of the culture container at the observation position is precedently detected by an auto-focus displacement sensor. In a case where an auto-focus control is performed on the basis of the position, an error between the precedently detected vertical position of the container at the observation position and a vertical position of the container at a time point when an observation region of the imaging optical system is scanned up to the observation position is acquired, and an objective lens is moved in an optical axis direction on the basis of the error.

Abstract: Information for assisting a doctor based on the oxygen saturation of an observation target is presented. An endoscope system includes a light source device, an image sensor, an oxygen saturation calculation unit, a distribution pattern generation unit, a disease state score calculation unit, and a monitor. The light source device emits light to irradiate the observation target. The image sensor images the observation target with reflected light of the light, and outputs an image signal. The oxygen saturation calculation unit calculates an oxygen saturation of the observation target based on the image signal. The distribution pattern generation unit generates a distribution pattern showing the distribution of the oxygen saturation. The disease state score calculation unit calculates a disease state score indicating the disease state of the observation target based on the distribution pattern. The monitor displays the disease state score or information based on the disease state score.

Abstract: A detection section detects a position of a container in a vertical direction, and an imaging optical system controller acquires an adjustment value of an imaging position of an imaging optical system according to the detected position. A correction section corrects the adjustment value according to a change in a refractive index of the container according to a temperature of the container. The imaging optical system controller adjusts an imaging position of an observation target on the basis of the corrected adjustment value.
