Abstract:
An image processing device for storing image data in a buffer memory and outputting image data stored in the buffer memory and outputting image data stored in the buffer memory for printing, said image processing device comprising:a non-volatile memory; a variable length compression unit for variable length compression of image data; a memory device control unit for storing variable length compression data compressed by the variable length compression unit, and reading out the variable length compression data stored in the non-volatile memory in accordance with a print command; a decoding unit for variable length expansion of variable length compression data for output to a printer; and a buffer control unit for storing the variable length compression data read from the non-volatile memory, reading out the data stored in a page buffer memory in accordance with a print command, and outputting the read out data to the decoding unit when the data are variable length compression data, and outputting the read out data to a printer when the data are not variable length compression data.
