1. A corrected image generating apparatus for generating a corrected image by correcting a deflection due to vibration of a camera in a raw image obtained by said camera which obtains the raw images of plural frames successively by scanning an object field of vision repeatedly using a one-dimensional image pickup device in which the plural light receiving sensors are arranged one-dimensionally in a scanning direction intersecting the arrangement direction of plural light receiving sensors composing the one-dimensional image pickup device, said corrected image generating apparatus comprising: a pattern matching portion for carrying out pattern matching processing about adjacent frames in each block obtained by dividing the raw image into grids; a feature point extracting portion for extracting the feature point on the pattern matching of the raw image according to a result of the pattern matching processing obtained by said pattern matching portion; a motion vector computing portion for obtaining the motion vector of said feature point based on a result of the pattern matching processing obtained by said pattern matching portion about the feature point extracted by said feature point extracting portion; and an image correcting portion for obtaining a corrected image in which deflection of the raw image is corrected based on the motion vector obtained by said motion vector computing portion about the feature point extracted by said feature point extracting portion.
