Drawing method for drawing image on two-dimensional screen
First Claim
Patent Images
1. A drawing method, comprising the steps of:
- setting a value for expressing distance from a virtual viewpoint to every predetermined compositional unit of a first image;
generating a second image;
defining a coefficient corresponding to the value for expressing the distance set to every predetermined compositional unit; and
synthesizing the first image and the second image based on the coefficient defined for every predetermined compositional unit.

Abstract
A value for expressing distance from a virtual viewpoint is set to every predetermined compositional unit of a first image; a second image is generated; a coefficient is defined corresponding to the value for expressing the distance set to every predetermined compositional unit; and the first image and the second image are synthesized based on the coefficient defined for every predetermined compositional unit. This successfully creates an image with a natural perspective by which the compositional unit is blurred according to the distance thereof from the virtual viewpoint, while causing only a small load to CPU.
