Abstract
The present invention provides a picture processing apparatus and method comprising a displacement computing unit which computes displacements in a UV coordinate system of a 2-dimensional picture texture to be pasted on a multidimensional figure from displacements in a texture coordinate system of the figure and an XY coordinate system onto which the figure is mapped and supplies the computed displacements to a displacement adjusting unit for adjusting the displacements by multiplying them by adjustment coefficients to produce adjusted displacements which are then supplied to a shrinkage-factor computing unit for computing a shrinkage factor to be used as a shrinkage factor of MIPMAP filtering.
