Abstract
An image processing apparatus configured to detect a position deviation between a first image and a second image includes a first memory configured to store motion vectors between the first image and the second image as a first motion vector group, a second memory configured to store, as a second motion vector group, motion vectors extracted from the first motion vector group determined to have a higher reliability than a predetermined threshold, an acceptable motion vector selection unit configured to calculate a temporary position deviation parameter from the second motion vector group, and select the motion vectors representing the position deviation as an acceptable motion vector group from the first motion vector group, using the temporary position deviation parameter, and a parameter estimation unit configured to estimate the position deviation parameter representing the position deviation from the acceptable motion vector group.
