Abstract:
An image processing system comprising:number-of-divisions determination means for determining how many bands one page is to be divided into,conversion means for converting code data of at least one page into intermediate code,an intermediate buffer for storing the intermediate code,selection means for selecting the intermediate code corresponding to a specific band out of said intermediate buffer,expansion means for expanding the intermediate code to bit map data, anda band memory for storing the resultant bit map data,whereinarea information addition means for adding area information indicating which band the code is valid on to the intermediate code;intermediate code determination means for determining whether or not elements of the preceding intermediate code differ from the corresponding elements of the subsequent intermediate code;control means for storing the corresponding elements of the subsequent intermediate code in said intermediate buffer if said intermediate code determination means determines that the elements of the preceding intermediate code differ from the corresponding elements of the subsequent intermediate code; andrestoration means for restoring the subsequent intermediate code using the preceding intermediate code when the intermediate code is output from said intermediate buffer to said expansion means.
