1. A drawing device that regards an object to be drawn as a collection of a plurality of polygons, and maps texture data onto the polygons, to thereby draw the object, the drawing device comprising: a storage circuit for storing respective information items of each of texture pixels constituting the texture data and at least one texture pixel in a vicinity of the each of the texture pixels, in a continuously-accessible region thereof; an address calculation circuit for calculating, based on texture coordinates corresponding to each pixel of the polygons, an address where a corresponding set of the information items are stored; a readout circuit for reading out the corresponding set of the information items from the address calculated by said address calculation circuit; and a synthesis circuit for synthesizing the corresponding set of the information items read out by said readout circuit.
