In this paper, we propose an automatic image enhancement tool for smart phone by using interactive differential evolution (IDE). From a remarkable progress of the camera sensor in mobile devices, people take pictures with their mobile phone instead of a digital camera. However, as they are not satisfied with their images in spite of the progress, they still want to edit their images by using mobile applications, which are usually complex and cause user fatigue, especially for beginners. To reduce it and make a simple interface, we exploit IDE, which is a kind of interactive evolutionary computation. Let the user IDE to evaluate the individuals. Because of the small parameters of the differential evolution (DE), we could make the tool simply and overcome the user fatigue. DE is also an efficient and fast evolutionary algorithm which uses the difference of the vectors. Subjective test shows the usefulness of the tool.
