Abstract:
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 raw images of a plurality of frames successively by scanning an object field of vision repeatedly, said corrected image generating apparatus comprising: a one-dimensional image pickup device to scan a raw image via a plurality of light receiving sensors arranged one-dimensionally in a scanning direction intersecting an arrangement direction of the plurality of light receiving sensors including the one-dimensional image pickup device; a pattern matching portion to divide the raw image into grids and to perform pattern matching processing about adjacent frames in blocks of the grids, the blocks of the grids being of a same size, to thereby provide pattern matching data; a feature point extracting portion to extract a block as a feature point on the pattern matching of the raw image, after the pattern matching processing has been performed and in accordance with the pattern matching data obtained by said pattern matching portion; a motion vector computing portion to obtain a motion vector of said feature point based on the pattern matching data obtained by said pattern matching portion about the feature point extracted by said feature point extracting portion; and an image correcting portion to obtain 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.
