RENDERING DEVICE, RENDERING METHOD AND RECORDING MEDIUM

摘要

A DMA controller reads image information recorded on a ROM by address unit from a front reading start position. A shift operator shifts a first data sequence of one row of the reading by only a designated number of bits, and generates a second data sequence. A DMA controller reads a third data sequence already stored in a VRAM writing start position. A controller performs a prescribed operation on the second data sequence and the third data sequence, and generates a fourth data sequence. The controller writes the generated fourth data sequence successively in a horizontal direction by address unit from the VRAM writing start position.
