Abstract
A picture processing device (100) includes: a mask generation unit (110x) which generates a masking picture (110aI) based on an edge in a first picture (101a); a feature point masking unit (111x) which masks extracted feature points with the generated masking picture (110aI); a rotation matrix calculation unit (112) which calculates a positional change between the first picture and a second picture (101a, 101b) using a feature point selected from the feature points as a result of the masking; and a picture correction unit (113) which uses the calculated change.
