Abstract
A control device includes: an acquisition unit configured to acquire first and second image signals generated by an imaging device having an autofocus function by capturing an observation target irradiated with first light and second light having different wavelength bands, respectively; a signal processor configured to detect detection information of the first and second image signals; and a controller configured to calculate a first focal length based on the detection information of the first image signal, calculate a second focal length based on the detection information of the second image signal, and set a focal length of the imaging device to capture the observation target irradiated with the second light to either the first or second focal length at least based on the detection information of the second image signal.
