| Abstract(in English) | This paper proposes a method of reproducing images based on their apparent sizes. The apparent size of spheres in close proximity to each other is first determined. From this determination, it becomes clear that the relative apparent sizes of objects are significantly different from photo-realistic sizes. A subjective resizing function is proposed based on the difference between photo-realistic sphere sizes and apparent sphere sizes of objects. A reproduced computer graphics image using the subjective resizing function adjusted to each individual is verified by an evaluation experiment. It was confirmed that resized images look more natural to each subject than ordinary photo-realistic images. Further studies of the subjective resizing function need to be carried out in order to better understand individual perceptions of apparent sizes. |
