TEXTURE ENCODER, TEXTURE DECODER, METHOD AND PROGRAM

PROBLEM TO BE SOLVED: To provide a texture encoder or the like capable of compressing a data amount. SOLUTION: This texture encoder has: a texture data acquisition means 101 acquiring data of a texture group acquired or produced under a plurality of different conditions; a block division means 102 blocking a plurality of pieces of pixel data wherein values corresponding to the conditions are within a first range and wherein pixel positions are within a second range among the texture group as one group, and dividing the data of the texture group into a plurality of pieces of block data; a block data encoding means 103 encoding each the piece of the divided block data; a block data connection means 104 connecting the encoded block data to generate encoded data of the texture group; and an output means 105 outputting the generated encoded data of the texture group.
