Image processing system, image processing method, and program

An image processing method comprising:

• obtaining a captured image of a document that includes a fixed part and an un-fixed part, the document being captured by an image reader or an image capture device;
• detecting a feature part of the fixed part based on the captured image;
• obtaining, in a case where the feature part is detected, a shaped image of the captured image such that a positional relationship of the feature part is aligned with a predetermined first positional relationship;
• and
• searching for, in a case where the feature part is not detected, a substitute feature part of the fixed part based on the captured image, wherein
• in a case where the feature part is not detected, the image processing method obtains the shaped image such that a position of the substitute feature part is aligned with a predetermined second position.

A non-transitory computer-readable information storage medium for storing a program for causing a computer to:

• obtain a captured image of a document that includes a fixed part and an un-fixed part, the document being captured by an image reader or an image capture device;
• detect a feature part of the fixed part based on the captured image;
• obtain, in a case where the feature part is detected, a shaped image of the captured image such that a positional relationship of the feature part is aligned with a predetermined first positional relationship;
• and
• search for, in a case where the feature part is not detected, a substitute feature part of the fixed part based on the captured image, wherein
• in a case where the feature part is not detected, the computer obtains the shaped image such that a position of the substitute feature part is aligned with a predetermined second position.
