PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of improving the drawing speed by averting the caching of texture data from an external memory to a cache memory which can interrupt the high-speed operation of texture mapping. SOLUTION: The image processing apparatus is provided with a control part 31 for determining whether a texture data utilization rate is a boundary value or larger in each triangle to which a texture is to be pasted, validating the cache memory 15 when the using rate is the boundary value or larger, and invalidating the cache memory 15 when the using rate is smaller than the boundary value, so that the caching of the texture data from the external memory 5 to the cache memory 15 will be executed, only when the texture data using rate of the triangle to which the texture is pasted is the boundary value or larger, and the caching will not be executed, when the utilization rate is smaller than the boundary value.
