According to an embodiment of the present invention, a high dynamic range composition unit composes a first image signal and a second image signal. A master control exposure value calculating unit calculates a master control exposure value based on one of the first and second image signals, which is predetermined as a master control signal. A sub-control exposure value calculating unit calculates a sub-control exposure value on a sub-control signal by multiplying the master control exposure value by a dynamic range ratio. The sub-control signal follows brightness control of the master control signal.
