As is well known, image quality is dependent on sharpness, tone scale reproduction, graininess and color reproduction characteristics of the observed image.Over the last 50 years many quality criteria have been proposed and used for image evaluation. However, image quality is also dependent on the scene content, particularly in subjective evaluations. It is reported that eye movements provide useful information in the analysis of subjective evaluations. Hence, in this paper the relationship between gazing areas and image quality is analyzed in terms of eye movements.We measured the eye movements of six observers during the viewing of seven kinds of images on a CRT. The gazing areas are the most important regions of the image for the observers, therefore its information can be applied to the development of improved data compression and transmission algorithms and systems.The purpose of this paper is to discuss and clarify the relationships between gazing areas and both subjective and objective image quality evaluations.
