Abstract
An image processing apparatus includes a feature region extracting section, a feature amount calculating section, a position calculating section, first and second selecting sections and a correction factor calculating section. The feature region extracting section extracts feature regions. The feature amount calculating section calculates feature amounts of the extracted feature regions. The position calculating section calculates positions of the extracted feature regions. The first selecting section selects pairs of feature regions, which are estimated to be common in the first and second images, based on the feature amounts and the positions. The second selecting section narrows down the selected pairs of feature regions based on similarity in relative positional relation between the feature regions of the first and second images. The correction factor calculating section calculates a correction factor used to correct position shift between the first and second images based on the narrowed pairs of feature regions.
