Abstract: PURPOSE: A label area division method is provided to enable a user to receive or purchase a product including a label by recognizing a label area from an input image. CONSTITUTION: An importance area creation unit creates a predetermined area of an input image as an importance area(S1000). A vertical edge detection unit detects two vertical edges from the importance area and creates an area which is covered with the vertical edges as a label candidate area(S2000). A label area encoding unit creates encoded label area code by calculating the similarity of a direction and a size between pixels in a boundary of the label candidate area(S4000). A label area separation unit separates an area matched with the label area code from the input image(S5000). [Reference numerals] (S1000) Creating an importance area; (S2000) Creating vertical edges and a label candidate area which is covered by the vertical edges; (S3000) Detecting horizontal edges which cross with vertical edges; (S4000) Creating a label area code connected to vertical edges and horizontal edges; (S5000) Dividing a label area matching with a label code area in an inputted image
