摘要
A data development device includes an LZ77 development part expanding data by referring to a dictionary including previous development result when data same to previous data is output, a PNG inverse filter performing arithmetic operation on development result of the LZ77 development part and image data previously output and outputting the image data, and a shared memory including an internal dictionary area and a line data area, the internal dictionary area storing previous development result referred by the LZ77 development part and the line data area storing the image data which is previously output and used by the PNG inverse filter. The shared memory has capacity for the internal dictionary area and capacity for the line data area set based on analysis result analyzing input data.
