A camera system includes a synchronization signal generator and a camera device separated from the synchronization signal generator. The synchronization signal generator generates a subframe synchronization signal having a constant period and a variable-frame synchronization signal having a variable period. The camera device further includes an internal synchronization signal generating unit that generates an internal synchronization signal; a phase adjusting unit that adjusts a phase of the internal synchronization signal so as to match a phase the subframe synchronization signal with a phase of the internal synchronization signal; and a synchronization signal selecting unit that selects the variable-frame synchronization signal as a synchronization signal to be used for picking up an image if the subframe synchronization signal corresponds in phase to the internal synchronization signal.
