发明名称 METHOD OF PERFORMING ADAPTIVE CONTRAST ENHANCEMENT USING HYPERLOIC TANGENT CURVE AND IMAGE HISTOGRAM
摘要 Disclosed is a method of performing contrast enhancement for an image. A mean luminance value is calculated with respect to an image that is read, the type of the image is determined based on the mean luminance value, a contrast reference curve is created by using a hyperbolic tangential function curve according to the type of the image, and the contrast of the image is enhanced by using the contrast reference curve.
