PURPOSE: To store necessary data for following processing without unnecessary information by forming an operation log executed on large picture data in interactive format and performing deletion from a log of pixel elements of the decision, computation, processing stop of necessary pixel elements, or the like. CONSTITUTION: A large picture including a handwriting by a scanner 12, A/D converter 14 and CPU 16 is edited in interactive format while operating a terminal equipment 30 and monitoring the display of the monitor. The log of operation information executed at this time is stored in the log file of the CPU 16. The contents of this log is oppositely tracked, and the CPU 16 operates the conversion of the large picture into a pixel element array, the decision of a necessary pixel element group, etc. Then, the pixel element on which the processing is completed is deleted from the log as well as an operation processing to the pixel element of this necessary group is performed. Then, only necessary data to the large picture including a mask, a hue, etc., is stored in a disk file 18 which is undesired increasing the capacity, or the like, and proper information for the processing in the after day is provided. |
