Perspective projection calculation device and perspective projection calculation method

摘要

In order to provide a perspective projection computation apparatus capable of processing a perspective projection correction at every high speed and accurately at every speed while avoiding an increase in the number of divisions, a method for generating a plurality of geometric parameters At least one surface gradient element coefficient calculation unit for calculating a coefficient indicating a triangular surface gradient defined in a three-dimensional space that can be commonly used for the surface gradient element coefficient calculation unit, And at least one correcting unit for correcting the perspective projection using the interpolation coefficient obtained by the interpolation coefficient calculating unit.;With such a configuration, there is an effect that a perspective projection calculation apparatus capable of processing the perspective projection correction at every high speed at an accurate speed can be obtained while avoiding an increase in the number of times of division.
