摘要： A surgical microscope system for use in a medical procedure. The surgical microscope system is controlled in a first mode of operation corresponding to a phase of the medical procedure and defining at least one setting for adjusting a set of adjustable optics. While in the first mode of operation, the surgical microscope system automatically determines, from a captured image, an indication that a second mode of operation is relevant. The mode of operation is switched to the second mode of operation.
