CHANGE PROCESSING SYSTEM FOR GRAPHICS DATA

摘要

PURPOSE:To convert the application graphics data into an OS format in a QS at a high speed by producing a data structure body and then omitting partly the graphics data conversion processing. CONSTITUTION:A pallet data analyzing part 3 produces a pallet data set (4) where the application pallet data 1 and the QS pallet data 2 are arranged for each bit. Then the pallet data sets are retrieved (5) to decide whether a pallet data set that has the same value as an OS pallet data set exist or not in an application pallet data set. If exists, other pallet data sets are checked (6). When such a retrieving operation is completed with respect to all OS pallet data sets, the graphics data conversion processing 9 is carried out at a graphics data converting part 8 with no use of a pallet table. Thus the processing 9 can be partly omitted.
