Image processing method, image processing device, and image processing system

摘要

An image processing device for obtaining a stable image of a high quality is provided. A dynamic range compression circuit executes a dynamic range compressing process for adding a value depending on a peripheral average pixel value to a pixel value of an input image. A contrast enhancement circuit executes a contrast enhancing process to a compressed image derived by the dynamic range compression circuit. Thus, a decrease in contrast of the whole image due to an excessive increase or decrease in density of the portion where the dynamic range compressing process was executed can be prevented.
