RULED LINE FRAME CORRECTION METHOD, RULED LINE FRAME CORRECTION DEVICE, AND RULED LINE FRAME CORRECTION PROGRAM

摘要

PROBLEM TO BE SOLVED: To precisely estimate a logical relationship between item names and between item name-item value even when an item name or an item value is recorded on a ledger sheet in a recording method without meeting predetermined requirements.SOLUTION: A thickness frame correction part 20 extracts a ruled line frame from a ledger sheet, and acquires at least a type or thickness of the ruled line, a character string in a frame, and a fill color of the frame as a piece of ruled line frame information of each ruled line frame. When the ruled line frame information of a plurality of ruled line frames meets preset ruled line frame coupling conditions, the plurality of ruled line frames are coupled with each other. When the ruled line frame information of the plurality of ruled line frames meets preset ruled line frame dividing conditions, the ruled line frames are divided. When the ruled line frame information of the plurality of ruled line frames meets preset ruled line frame deletion conditions, the ruled line frames are deleted.SELECTED DRAWING: Figure 3-1
