PURPOSE: A test chart set and a test system for testing a wide-area backlight correcting function of a digital photographing device are provided to perform a test of a wide-area backlight correcting function of an image photographing device in a quite bright surrounding background such as a case being instantaneously exposed to strong and bright lights. CONSTITUTION: A test chart set for testing a wide-area backlight correcting function of a digital photographing device comprises a normal test chart(100), a high brightness test chart(200), and a low brightness test chart(300). The normal test chart comprises a normal basis and normal annulus patterns. The normal basis is colored with colors of medium-brightness. A plurality of normal annulus patterns in which colors having gradual brightness are colored is arranged in an annulus shape in the normal annulus pattern. The high brightness test chart comprises a high brightness basis and high brightness annulus patterns. The high brightness basis is colored with colors having the brightness brighter than the medium-brightness. The low brightness test chart comprises a low brightness basis and low brightness annulus patterns.
