Abstract

Text is generated from an object. Text is generated from a first object. The first object includes a second object and a third object. A step of detecting coordinate data of the second object is included. A step of detecting coordinate data of the third object is included. A step of extracting positional relation between the second object and the third object from coordinate data is included. A step of converting the extracted positional relation into graph data is included. A step of generating text about the positional relation between the second object and the third object from graph data is included.

First claim

What is claimed is:

1 . A computer comprising a storage storing a program, the program comprising processing procedure configured to:
display a first object and a second object in a drawing on a display device; display graph data formed based on the first object and the second object on the display device; generate a text about a positional relation between the first object and the second object from the graph data; and display the text on the display device, wherein the graph data comprises positional relation data of the first object and the second object, and wherein the positional relation data is obtained after removing an overlap region between the first object and the second object.

2 . The computer according to claim 1 ,
wherein the text comprises any one or more pieces of data that one of the objects is on the left, right, upper, or lower side of the other object, one of the objects is included in the other object, or one of the objects is in contact or not in contact with the other object.

3 . The computer according to claim 1 ,
further comprising processing procedure configured to generate graph data from the positional relation data relative to the reference object.

4 . The computer according to claim 1 ,
wherein the drawing is a patent drawing.

5 . The computer according to claim 1 ,
further comprising processing procedure configured to convert the first object into a vector image, wherein the first object is a raster image.

6 . The computer according to claim 5 ,
further comprising processing procedure configured to convert the first object into a vector image after being converted into the raster image.
