To solve the problem that depth is not sensed, and there is inclination to be bored with too superficial expression by the merely printed expression of a solid style picture of computer graphics; that moreover since the expression becomes the color of a single color only by film sheets, it is difficult to give a spatial effect; and that further since cost is high in actual metal cut characters and carving characters, the change of the display is very difficult.
A solid style picture expressed by the gradation, blurring, shadow or the like of a computer graphic is created, a transparent sheet is superimposed, an illustration clipped in a form which is along a picture and another sheet including a picture are stuck, thereby three-dimensional expression is carried out in spite of the flat surface.
