Image processing apparatus
First Claim
1. An image processing apparatus, comprising:
- a background density distribution estimating part that estimates density distribution of pixels in a background area in an image to be processed;
an area density distribution estimating part that estimates density distribution in a designated area in the image; and
an entry existence judging part that judges existence or not of entry of predetermined information in the designated area, based on the density distribution of the pixels in the background area estimated by said background density distribution estimating part and the density distribution in the designated area estimated by said area density distribution estimating part.

Abstract
An image processing apparatus of the present invention includes: a background density distribution estimating part 12 that estimates density distribution of background pixels; an area density distribution estimating part 13 that estimates density distribution in each of areas into which an input image is divided; an entry existence judging part 14 that judges the existence or not of the entry of predetermined information based on the density distribution of the background pixels and the density distribution in the relevant area; and a judgment result output part 15 that outputs a judgment result indicating whether or not there exists the entry of the predetermined information in the area being the judgment target of the entry existence judging part 14.

11. An image processing method where a computer processes an image, comprising:
-
estimating, by the computer, density distribution of background pixels out of pixels forming the image to be processed; estimating, by the computer, density distribution in a predetermined area in the image; judging, by the computer, existence or not of entry of a character which is predetermined information, in the designated area, based on the estimated density distribution of the background pixels and the estimated density distribution in the designated area.
