1. A control device comprising:
circuitry configured to:
detect, for focusing on a predetermined subject included in an observation image of an eye of a patient that is a surgical operation target, an initial in-focus position on a basis of an autofocus image of the eye of the patient off-center from the observation image;
determine an offset value indicating a distance between a target eye organ that is inside a corneal endothelium of the eye and the initial in-focus position on a basis of information regarding structure of an eyeball; and
calculate an in-focus position for a center of the observation image that is a focus position focused on the target eye organ on a basis of the offset value and the initial in-focus position.
