1. A medical observation system comprising:
a camera head for use with a plurality of types of units of observation systems, the observation system configured to guide an illumination light to a subject and to guide an observation light from the subject, the camera head including an image sensor configured to receive the observation light from the observation system and generate an image signal; and
circuitry configured to:
apply signal processing to the image signal generated by the image sensor,
detect, based on a signal value in a first wavelength band included in a wavelength band of the observation light from the subject in the image signal, whether or not a filter is disposed on an optical path of the observation light, the filter being a filter that cuts the first wavelength band of the observation light over an entirety of the image sensor.
