Abstract	The technologies for image contrast enhancement are improved evidently since the popularity of consumer electronics and image processing in the last decade. Based on Histogram Equalization (HE), this paper proposes a simple contrast enhancement scheme named Adaptively Increasing the Value of Histogram (AIVHE). It provides a convenient and effective mechanism to control the rate of contrast enhancement by means of an adaptive parameter, α(k), and a user defined value, β. AIVHE offers a gradually increment by the mean brightness of the image to modify the original probability density function (PDF). The simulation results show that the method can outperform contrast enhancement than other methods.
