Abstract
One or more character strings are extracted from within an inputted image. The extracted character strings are retrieved to find one or more identical character strings. A determination is then made as to whether or not the identical character strings are laid out regularly, with processing performed on the inputted image depending on the findings of the determination.
Claims15
An image processing apparatus, comprising:
- a retrieval unit adapted to extract a plurality of character strings that are present within an inputted image, and to retrieve a plurality of identical character strings within the plurality of extracted character strings;
- a determination unit adapted to determine whether or not the plurality of identical character strings retrieved by said retrieval unit are laid out regularly;
- and
- a processing unit adapted to carry out a process on the inputted image in accordance with a determination result of the determination unit,
- wherein said retrieval unit extracts a plurality of character strings that are present within the inputted image after a light color has been removed from the inputted image, and retrieves a plurality of identical character strings from among the plurality of extracted character strings;
- and
- said processing unit carries out a process on the inputted image, as it exists prior to the light color being removed therefrom, in accordance with a determination result from said determination unit.

A control method of an image processing apparatus, comprising:
- extracting a plurality of character strings that are present within an inputted image;
- retrieving a plurality of identical character strings within the plurality of extracted character strings;
- determining whether or not the plurality of identical character strings retrieved in said retrieving step are laid out regularly;
- and
- carrying out a process on the inputted image in accordance with a determination result of said determining step,
- wherein said extracting step extracts a plurality of character strings that are present within the inputted image after a light color has been removed from the inputted image, and said retrieving step retrieves a plurality of identical character strings from among the plurality of extracted character strings;
- and
- the process is carried out on the inputted image, as it exists prior to the light color being removed therefrom, in accordance with a determination result of said determining step.
