長時間を要する、という問題があった。Conventionally, a roughly cylindrical reflector with reflective surfaces is placed approximately in the center of a distorted painting, and by visually observing the sides of this reflector, a normal painting without distortion can be seen. A game surface called trompe l'oeil or zeya-e is known. To create this distorted painting, a normal painting was copied onto a reflective object and distorted, and the artist visually described the distorted painting. Therefore, there is a problem in that it takes a long time to create a distorted painting.

。Next, a method of creating a distorted painting using an optical method will be explained. As shown in FIG. 5, a cylindrical reflector 10 is set upright on the photographic paper 8, and an image of the original plate 14 on which a normal painting without distortion is imaged is projected using the cylindrical reflector 12f. An image is formed on the photographic paper s through the reflective surface of the body 0.

This light beam is transmitted to the first optical system 12+), the original plate 14, the second optical system 120. Aperture 12111 and cylindrical reflector 10
The light reaches the photographic paper 8 through the reflective surface of the original plate 14 and forms an image on the photographic paper 8. In this case, since the cylindrical reflector 10 exists on 9"C1'1IllI of the second YC system 12C, the image formed on the photographic paper 8"2 deviates from the Gaussian region and has a remarkable spherical convergence. It turns out. Therefore, in this optical method, the number of apertures of the aperture 12e installed immediately before the second optical system 120 is minimized, that is, the aperture 12e is kept open, and the aperture number of the aperture 12e is set to a minimum. The number of apertures is gradually increased, that is, the aperture 1281 is gradually stopped down to increase the depth of focus. As a result, the cylindrical reflector 1 of the image on the photographic paper 8
The focus gradually comes from the point closest to 0 to the point farthest from 0, and an overall image with good clarity is obtained.
