Abstract
An observation system includes an observation optical system, an imaging device, an observation focus adjustment unit, a detector, and a processor. The observation optical system guides an observation luminous flux from a biological object being an observation target. The imaging device captures an observation image of the biological object, by receiving the observation luminous flux guided by the observation optical system. The observation focus adjustment unit adjusts a focus of the observation optical system. The detector detects at least one of a direction of a line of sight of the user, voice generated by the user, or a gesture of the user. The processor causes the observation image to be displayed on a display, and adjusts a focus of a target region concentrated on by the user in the observation image, by driving the observation focus adjustment unit based on a detection result by the detector.
