Abstract
Techniques to evaluate image quality are necessary. However, several problems to be investigated still remain in the evaluation of the image quality. Though it is difficult to evaluate the image quality totally, the sharpness and graininess are focused on as components of total image quality. As examples of the evaluation and improvement of image quality, two experimental results are shown in this paper. At fist, the outline and remarks in the evaluation of image quality are described. Then experimental results about evaluation of multi-level error diffusion images and improvement of noisy images without sharpness degradation are presented. Finally future problems and the conclusions are addressed.
