[Object] To provide a medical observation device and a control method. [Solution] Provided is a medical observation device including: an imaging optical system including an objective optical system that condenses light from a subject and two image-forming optical systems which have optical axes different from an optical axis of the objective optical system and which cause light condensed by the objective optical system to form an image; and a control unit configured to cause an autofocus operation to be executed by causing a focusing optical member included in the objective optical system to move.

Medical observation device and control method

An image pickup device having an auto-focus feature of adjusting a focus lens to focus on a picked-up image of an object, a zoom feature of changing a focus distance, and a telemacro-mode shooting feature of obtaining generally-difficult close-range focus by fixing the focus distance to a telescope end. The image pickup device switches between an auto-focus mode and a manual mode. Likewise the device switches between a telemacro mode and a normal mode. The zoom lens is driven to adjust the focus distance and the focus lens is driven to adjust the shooting distance. A controller drives the zoom lens drive unit to move the zoom lens to a telescope end when the normal mode is switched to the telemacro mode; and drives the focus lens drive unit to move the focus lens to an object-closest end when in the telemacro mode.
