PURPOSE:To convert an original picture according to a given 3-dimensional geometric structure form and to produce the exchange address of the new converted image, by using a form operator, a form shift rotary operator, a see-through conversion operator, a stopgap operator, an image coordinate corresponding operator, etc. CONSTITUTION:An original image coordinate generator 11 of a conversion address producer 17 delivers the coordinate value corresponding to each apex of a 2-dimensional polygon corresponding to an original image plane. A form operator 12 delivers the form coordinate value by means of the given formula and coefficient of a 3-dimensional geometric structure. A form shift rotary operator 13 delivers the space coordinate value according to the position and direction of said geometric structure. A see-through converter 14 delivers the new image coordinate value according to the visual point position and the screen position within a 3-dimensional space. Furthermore a stopgap operator 15 delivers the picture element coordinate value within a polygon on a new image plane. Then an image coordinate corresponding operator 16 delivers the spot coordinate value 191 on the original image plane according to both original and new image coordinate values. |
