摘　　要：图像对比度能增加图像变化的动态范围以利于后续处理。随着原始图像特征和应用需求的变化,图像对比度增强的研究也在继续。文中系统讨论了图像对比度增强研究的目的和现状,分析了图像对比度增强研究中主流算法的特点和局限性,最后指出了图像对比度增强研究的未来发展方向。Image contrast enhancement is an important research content in the field of image processing technol-ogy, and it can extend the gray-value dynamic range. The technology significantly improves the visual effects and pro-vides processed images more suitable to analyze. Image contrast has been studied for decades. However, with the change of the original image characteristics and application requirements change, the image contrast enhancement re-search continues to proceed. This paper systematically introduces the purpose and the current research status of image contrast enhancement, and analyzes the characteristics and limitations of the mainstream algorithm about image con-trast enhancement in recent years. Finally, this paper points out the future direction of the image contrast enhance-ment technique.
