Dependence of Optimization Condition of Edge Enhancement on Observation Distances

摘要：

It is important to emphasize the contour of image in imaging sys-tem to make us feel the image sharp. The edge enhancement is effective to improve subjective estimation of image quality. But if the edge is enhanced too much, the image becomes unnatural. The space frequency components of the image change when the observation distance is different and the effect of the edge enhancement is considered to be different. The image qualities of the simple object captured by digital camera and the object made by CG was examined under various conditions such us the observation distance, illumination. The optimization conditions of edge enhancement by a subjective evaluation are obtained. The results of subjective estimation are discussed from the view-point of HVS (Human Visual System).
