摘要
Provided is a text string cut out method whereby a text frame is carried out from a paper image in which paper whereon a text string has been printed is image captured and a text image cut out. A region having a size which encapsulates text which forms a text string is set as a text part a ring shaped region which is adjacent to the text part is set as an exterior circumference part and a region which encapsulates a plurality of the exterior circumference regions is set as a text string frame. A difference is computed by subtracting the feature value of the text part from the feature value of the exterior circumference part with all of the text parts which are included in the text string frame as a subject while moving the location of the text string frame in the paper image and a text string frame evaluation value is computed based on the difference thereof. The image within the text part is cut out using the text frame which is set at the location with the highest text string frame evaluation value.
