1. An image analyzing device comprising: a target recognition unit to recognize an area where a target is displayed based on a feature value of an input image to generate a recognition result; a space recognition unit to generate space recognition information to recognize spatial properties of each portion of the input image; a feature dividing unit to divide the image into a plurality of similar areas according to similarity in feature value of the input image, the similar area having a similar feature value; a space specification data obtainer to obtain specified attribute data of the spatial properties to be referred to, from image areas around the recognized area where the target is displayed; and a recognition finalizing unit to recognize the spatial properties according to the space recognition information, and determine whether the recognition result is appropriate at the portion where the target is displayed, based on the distribution of the similar areas of the specified spatial properties in the image areas around the recognized area where the target is displayed.
