PURPOSE: A brightness correcting system for an LED electric board is provided to easily control the brightness of each LED module by correcting the brightness measured at each LED module within a reference range. CONSTITUTION: A brightness measuring camera(110) measures brightness with an LED module unit from an LED electric board composed of a plurality of LED modules. A control unit corrects the brightness of each LED module unit within the reference range. A correction controller(130) controls the brightness of each LED module of the LED electric board to the corrected brightness by the control unit. A correction driver(140) drives each LED module with the brightness controlled by the correction controller.
