1. A sub-region indicating information generating method for a two-dimensional (2D) image comprising a background and an object, the method comprising:

  • receiving sub-region dividing information to divide the object into a plurality of sub-regions, wherein the sub-region dividing information comprises information to divide the object into a transparent region through which the background is visible and an opaque region through which the background is not visible; and

    generating, by a generating apparatus, sub-region indicating information to separately identify each of the plurality of sub-regions divided according to the sub-region dividing information, wherein the generating of the sub-region indicating information comprises generating the sub-region indicating information to separately identify the transparent region and the opaque region,wherein the generated sub-region indicating information is used to convert the 2D image of the object into a three-dimensional (3D) image of the object relative to the background,wherein the generating of the sub-region indicating information to separately identify the transparent region and the opaque region comprises;

    generating a transparent region indicating mask to identify the transparent region; and

    generating an opaque region indicating mask to identify the opaque region, andwherein the generating of the opaque region indicating mask comprises generating a mask in which the opaque region has a first color and a remaining region of the 2D image other than the opaque region has a second color, different from the first color.
