An apparatus for automatically computing a gamma correction curve and a method thereof are provided to save time due to automatic computation of the gamma correction curve, thereby more accurately extracting the gamma correction curve. An image obtaining unit(140) inputs image data of a color chart through an image interface. A coordinate calculation unit(190) compare an input brightness value of each ROI with a target brightness value of each ROI which is preset to compute a gamma correction coordinate with regard to spots of the gamma correction curve. A curve calculation unit(200) calculates the gamma correction curve by applying an interpolation method to gamma correction coordinates.
