Abstract
An image processing apparatus is to: detect a first edge point group comprising a set of edge points between a document background area and a document area in a read image of a document; calculate feature amounts from a plurality of edge points in the first edge point group and compose an edge point feature amount group; calculate a distribution of the feature amounts of the plurality of edge points from the edge point feature amount group and calculate a feature amount corresponding to a maximum distribution; select edge points corresponding to the maximum distribution from the first edge point group and select a second edge point group using a range of the feature amount corresponding to the maximum distribution; and calculate an edge straight line approximating the second edge point group.
