According to one embodiment, a remote head camera includes a camera control unit, and a camera head configured to be connected to the camera control unit and including an imaging device, a drive signal generator, and a format identifying unit. The drive signal generator generates a drive signal for driving the imaging device. The format identifying unit identifies a format of the imaging device based on a clock count in a synchronization period from a first synchronization pulse to a second synchronization pulse output after the first synchronization pulse. The first synchronization pulse and the second synchronization pulse constitutes a synchronization signal.
