Abstract
On this subject, I propose a conceptual figure of the "visual-imagination" as "thinking faculty by the visual imagery". The conceptual figure is verified by analysis of lessons and an image classification figure. A proposal of the lesson program based on the concept of this visual-imagination is assumed as future deployment of this subject. The following is the composition of this subject: a proposition of the concept about visual-imagination, the confirmation of preceding research about the formation process of imaginative faculty, a hypothesis of the formation of visual-imagination, the verification of a conceptual figure of the formation of the visual-imagination.
