Abstract
Provided are an image processing apparatus, an image processing method, a computer-readable medium storing a computer program and an image processing system improving edge detection precision at the time of flare occurrence. The image processing apparatus includes an input unit for taking image data including a document region, a first candidate detector for detecting a first candidate of an edge point constituting a boundary line of the document region by scanning binarized image of the image data with a predetermined pattern along a line, a second candidate detector for detecting a second candidate of an edge point based on differential value of pixels adjoining each other, and an edge point determination unit for determining the second candidate as an edge point when the second candidate is positioned more inside of the document region than the first candidate, and otherwise determines the first candidate as an edge point.
