1. An image processing apparatus comprising:
- a first interface configured to receive a first image from a first external apparatus;
a second interface configured to receive a second image from a second external apparatus, wherein the first image is different from the second image; and
a processor configured to;
extract a first character string appearing on the first image, and a second character string appearing on the second image;
determine that both the first character string and the second character string correspond to a photographed subject in the first image and second image;
cut out each of the characters constituting the first character string, in units of a character;
cut out each of the characters constituting the second character string, in units of a character;
calculate a first similarity degree group which is composed of similarity degrees between the respective characters constituting the first character string and respective candidate characters in a candidate character group;
calculate a second similarity degree group which is composed of similarity degrees between the respective characters constituting the second character string and the respective candidate characters in the candidate character group; and
recognize a character string of the first subject, based on the first similarity degree group and the second similarity degree group.

Abstract
According to one embodiment, an image processing apparatus includes a calculation unit and a recognition unit. The calculation unit is configured to calculate a first similarity degree group which is composed of similarity degrees between respective characters constituting a first character string appearing on a first image and respective candidate characters in a candidate character group, and to calculate a second similarity degree group which is composed of similarity degrees between respective characters constituting a second character string appearing on a second image and the respective candidate characters in the candidate character group.

8. An image processing method comprising:
-
extracting a first character string appearing on a first image received from a first external apparatus; extracting a second character string appearing on a second image received from a second external apparatus, wherein the first image is different from the second image; determining that both the first character string and the second character string correspond to a photographed subject in the first image and second image; cutting out each of the characters constituting the first character string, in units of a character; cutting out each of the characters constituting the second character string, in units of a character; calculating a first similarity degree group which is composed of similarity degrees between the respective characters constituting the first character string and respective candidate characters in a candidate character group; calculating a second similarity degree group which is composed of similarity degrees between the respective characters constituting the second character string and the respective candidate characters in the candidate character group; and recognizing a character string of the first subject, based on the first similarity degree group and the second similarity degree group.

9. A computer-readable, non-transitory storage medium having stored thereon a program which is executable by a computer, the program controlling the computer to execute functions of:
-
extracting a first character string appearing on a first image received from a first external apparatus; extracting a second character string appearing on a second image received from a second external apparatus, wherein the first image is different from the second image; determining that both the first character string and the second character string correspond to a first photographed subject in the first image and second image; cutting out each of the characters constituting the first character string, in units of a character; cutting out each of the characters constituting the second character string, in units of a character; calculating a first similarity degree group which is composed of similarity degrees between the respective characters constituting the first character string and respective candidate characters in a candidate character group; calculating a second similarity degree group which is composed of similarity degrees between the respective characters constituting the second character string and the respective candidate characters in the candidate character group; and recognizing a character string of the first subject, based on the first similarity degree group and the second similarity degree group.
