1. An image generating apparatus for generating an output image based on a panorama image that is captured and input by a user holding the image generating apparatus, the panorama image including an image of at least a portion of the user'"'"'s hand, the image generating apparatus comprising:

  • a processor; and

    a memory storing program instructions that cause the processor toinput an output range parameter and a correction parameter, the output range parameter designating an output range in the panorama image, and the correction parameter designating a portion of the panorama image including the image of at least a portion of the user'"'"'s hand as a correction part to be masked in the output image;

    set a first projection surface indicating a surface of a range to be output to the output image;

    set a second projection surface formed by moving the first projection surface to an area indicated by the output range parameter;

    set first coordinates on the first projection surface;

    set second coordinates, which correspond to the first coordinates, on the second projection surface;

    set a sphere inscribed in the first projection surface and the second projection surface;

    calculate a distance between the first coordinates on the first projection surface and the second coordinates on the second projection surface based on an arc length calculated based on a radius of the sphere and a length of one side of the first projection surface;

    calculate a similarity between pixels in the correction part and peripheral pixels of the correction part;

    mask the pixels of the correction part in the output image, with pixels of a value corresponding to the similarity between the pixels in the correction part and the peripheral pixels of the correction part; and

    display on a display device, the output image in which the value of the pixels of the correction part is changed to the pixels of the value corresponding to the similarity.
