1. A medical control device comprising:
a first clock generation circuit configured to generate a first clock;
a first synchronization signal generation circuit configured to generate a first synchronization signal based on the first clock;
a second clock generation circuit configured to generate a second clock; and
a second synchronization signal generation circuit configured to generate a second synchronization signal for operating a medical observation device based on the first synchronization signal and the second clock,
wherein the second synchronization signal generation circuit is configured to individually execute:
a first setting process of setting a transition timing at which the second synchronization signal transitions in correspondence with a transition of the first synchronization signal at a first transition timing, being an initial timing, of the input first synchronization signal; and
a second setting process of setting a transition timing at which the second synchronization signal transitions in correspondence with a transition of the first synchronization signal at a second transition timing, being a second or subsequent timing, of the first synchronization signal,
the first setting process performs setting of a transition timing at which the second synchronization signal transitions in correspondence with the transition of the first synchronization signal at the first transition timing by switching the first transition timing to a transition timing of the second clock,
the second setting process performs setting of a transition timing at which the second synchronization signal transitions in correspondence with the transition of the first synchronization signal at the second transition timing based on a position on a time axis of the second transition timing,
determine, in the second setting process, whether the position of the second transition timing on the time axis is located within a specific time width centered on a reference timing corresponding to a cycle of the first synchronization signal, and
based on the determination result, set the transition timing at which the second synchronization signal transitions in correspondence with the transition of the first synchronization signal at the second transition timing.
