DATA DEVELOPMENT DEVICE AND DATA DEVELOPMENT METHOD

摘要

deployment device data dictionary containing the results of the previous deployment when the same data as the previous data is output Sharing of LZ77 which extends the data development section, performing an arithmetic operation on the result and prior to the deployment of the output image data comprises a PNG inverse filter LZ77 development section, and the inner region and the line dictionary data area and outputting the image data by referring a memory, an internal dictionary area stores the previous line of development results and data area are referred to by the LZ77 development section, and outputs the previously stored image data to be used by the PNG inverse filter. The shared memory has a capacity for a capacitor line and the internal dictionary area for the data area is set based on the analysis result of analyzing the input data.
