Abstract
A first image is inputted, and an object area for mapping is determined on the first image. Transformation parameters for the mapping are calculated pixel by pixel from the attributes of the first image in the object area, a second image to be mapped into at least one part of the object area is generated, and the second image is mapped pixel by pixel in the object area of the first image operating the transformation parameters so as to generate a third image. When an image simulation for changing the color and texture in an area of a color or monochromatic gray scale image is performed, an image simulation for ignoring effects of fine texture on the initial image and reflecting the shadow and shade can be realized. When the same texture image is mapped one after another in a plurality of areas on a projection of a perspectively projected three-dimensional space which are originally on the same plane in the original three-dimensional space, by calculating the coordinate values on the projection for setting the parameters for projection transformation from the coordinate values of a smaller number of points, the operator's job of extracting coordinates values can be reduced.
