PURPOSE: A synthetic image providing system which enables an image brightness control and an image brightness controlling method thereof are provided to make the brightness of a synthetic image uniform in case of synthesizing multiple photographic images. CONSTITUTION: A communication unit (600) communicates with multiple photographing devices. An image processing unit (300) includes a brightness density calculating unit (321), a similarity measuring unit (322), a parameter acquisition unit (323), and a parameter transmitting unit (324). The image processing unit determines a gain value of any one photographing device among the multiple photographing devices as a setting parameter based on inputted images. The image processing unit delivers the set setting parameter to the rest of the photographing devices except the one photographing device through the communication unit.
