Abstract:
An image-processing device, having means for interpolation in which during mapping of texture cells representing the surface pattern of the object which is to be displayed, colour boundaries are interpolated by blending the colours of the texture cells contained within prescribed limits, wherein said means of interpolation comprising:means for determining size, in which the size of filter for stipulating the area which is subject to interpolation is determined:means for determining position, in which a filter of the stipulated size is moved one by one over the texture cells which are to be mapped, and the position is determined;means for extracting, in which the colour values of the texture cells which overlap with the filter in each position are extracted;means for blending color values, in which extracted color values for every texture cell are blended in proportion to the area of overlap between the texture cell in question and the filter; andmeans for mapping, in which the blended color values are mapped on each pixel which corresponds to a position of the filter.
