Medical imaging apparatus and medical observation system

A medical imaging apparatus to which a fiberscope including a plurality of optical fibers is connectable, the medical imaging apparatus comprising:

• an image sensor configured to capture a subject image of a subject gathered by the fiberscope and emitted from proximal ends of the plurality of optical fibers;
• a lens unit including a focus lens moving along an optical axis to adjust a focus, the lens unit being configured to form the subject image emitted from the proximal ends of the plurality of optical fibers on the image sensor;
• lens driving circuitry configured to move the focus lens along the optical axis;
• and
• a lens controller configured to perform, when the fiberscope is connected to the medical imaging apparatus, a first auto-focus control of operating the lens driving circuitry to move the focus lens in a first movement range, evaluating a focusing state of the subject image, and positioning the focus lens at a position deviated from a first lens position at which the proximal ends of the optical fibers are focused.
