    • The present invention provides two-scale tone management of an input image. A method of providing two-scale tone management contains the steps of: separating the input image into a base layer and a detail layer; separating a model image into a base layer and a detail layer; analyzing the input image globally for global contrast; analyzing the input image locally for local contrast; and performing detail preservation of the input image. A system contains a memory and a processor, where the processor is configured by the memory to perform the steps of: separating the input image into a base layer and a detail layer; separating a model image into a base layer and a detail layer; analyzing the input image globally for global contrast; analyzing the input image locally for local contrast; and performing detail preservation of the input image.
    • 本发明提供了输入图像的两尺度音调管理。 提供两级音调管理的方法包括以下步骤:将输入图像分离成基本层和细节层; 将模型图像分离成基本层和细节层; 全局对比分析输入图像; 本地分析输入图像以进行局部对比度; 并执行输入图像的细节保存。 系统包含存储器和处理器,其中处理器由存储器配置以执行以下步骤:将输入图像分离成基本层和细节层; 将模型图像分离成基本层和细节层; 全局对比分析输入图像; 本地分析输入图像以进行局部对比度; 并执行输入图像的细节保存。
