PROBLEM TO BE SOLVED: To enable layout analysis of an unknown form not registered in a system. An item extraction unit 2 uses an object detection algorithm by deep learning to extract an item area including an item name printed in print on a form, and sets an item area included in the form image as an attribute. Extract individually with classification. The handwriting area extraction unit 3 individually extracts a handwritten character area including a character string written in handwritten characters on the form from the form image.
