According to one embodiment, an input unit inputs text data. An existence rank database stores an existence rank of each character included in the text data. The existence rank is a statistical rank of the number of each character among the number of all characters included in the text data. A decision unit decides whether the existence rank of each character of the text data is higher than a predetermined rank, by referring to the existence rank database. A texture generation unit generates a texture of a character having the existence rank higher than the predetermined rank, by using outline data of the character. A texture rendering unit renders the texture. A polygon generation unit generates a polygon mesh of a character having the existence rank lower than the predetermined rank, by using outline data of the character. A polygon rendering unit renders the polygon mesh.
