Patent Images

1. An image processing apparatus comprising:

  • a processor programmed to;

    set a circumscribed area that includes a small-sheet image in a first image;

    detect an edge pixel of the small-sheet image;

    determine an effective edge of the small-sheet image based on a spatial relationship between (i) the circumscribed area set by the processor and (ii) the detected edge pixel of the small-sheet image, the spatial relationship including at least one of;

    (i) a distance between the detected edge pixel and a side of the circumscribed area; and

    (ii) a positional difference between the detected edge pixel and an adjacent edge pixel;

    determine that the small-sheet image in the first image is unsuccessfully extracted based on the determined effective edge; and

    in response to determining that the small-sheet image in the first image is unsuccessfully extracted, generate a second image by combining the small-sheet image with another small-sheet image that is also determined to be unsuccessfully extracted.
