An image discrimination device discriminates among image attributes indicating image types. An edge calculating section calculates an edge direction in each processing unit including a predetermined number of pixels of an image. A local connectivity calculating section calculates local connectivity intensity indicating a degree of alignment with the edge direction of the surrounding processing unit in each of the processing units based on the calculated edge direction. An image attribute discrimination section discriminates among the image attributes in each attribute discrimination region including a predetermined number of processing units of the image using the local connectivity intensity of the processing unit in the attribute discrimination region.
