Patent Images

1. An image processing device, comprising:

  • an image obtainer which obtains a chronological sequence of a plurality of images, sets one of the plurality of images obtained as a reference image, and sets a remainder of the plurality of images as object images;

    a projective transformation matrix calculator which calculates a projective transformation matrix for converting each of main subject portions of respective ones of the plurality of object images to be aligned so as to be superimposed on a main subject portion of the reference image;

    an intermediate image generator which generates a plurality of intermediate images by applying different predetermined intensity ratios to respective ones of the plurality of object images, wherein each of the plurality of intermediate images is obtained by averaging the reference image and each of the plurality of object images to which the projection transformation matrix has been applied; and

    an image combiner which combines the plurality of intermediate images.
