Image recognition apparatus, commodity information processing apparatus and image recognition method

A commodity information processing apparatus, comprising:

• a camera interface;
• and
• a controller configured to execute a settlement process based on first and second images received through the camera interface in this order, by:
• specifying a first pattern area within the first image,
• decoding an identification pattern of an object included in the first pattern area,
• carrying out determination of whether or not the first image and the second image match,
• responsive to determining that the first image and the second image do not match, by the determination, specifying a second pattern area within the second image, and decoding an identification pattern of the object included in the second pattern area,
• responsive to determining that the first image and the second image match, by the determination, acquiring commodity information corresponding to the decoded identification pattern in the first pattern area, and
• executing a settlement process based on the acquired commodity information.

An image recognition method, comprising:

• acquiring a first image;
• specifying a first pattern area within the acquired first image;
• decoding an identification pattern of an object included in the first pattern area;
• acquiring a second image after the acquisition of the first image;
• carrying out determination of whether or not the first image and the second image match;
• responsive to determining that the first image and the second image do not match, by the determination, specifying a second pattern area within the second image and decoding an identification pattern of the object included in the second pattern area, and
• responsive to determining that the first image and the second image match, by the determination, acquiring commodity information corresponding to the decoded identification pattern in the first pattern area.
