This paper addresses the problem of creating new methods of image enhancement in automatic mode focused on use in mobile and wireless applications. This work aims to increase the efficiency of image enhancement through intensity transformations. To achieve this aim, we propose a new approach to enhance the images based on an estimate of the cumulative distribution for the sub-ranges of the brightness scale. To demonstrate the capabilities of this approach, proposes a new image enhancement technique by parameter-free intensity transforming. The proposed technique allows to effectively increasing the contrast of complex images without the appearance of unwanted artifacts. The results of experimental research using no-reference metrics and expert estimates of image contrast indicate the effectiveness of the proposed technique.
