1. An image processing apparatus comprising:

  • an image input unit for capturing image information including distance information to each portion of an object to be photographed;

    a parameter input unit for inputting a parameter from which an effective aperture and focal length of the an assumed image sensing optical system can be derived;

    an in-focal point position designation unit for designating an in-focal point position of the assumed image sensing optical system;

    a blur state calculation unit for calculating a blur state from the distance information input by said image input unit, the in-focal point position designated by said in-focal point position designation unit, and the parameter input by said parameter input unit; and

    an image processing unit for applying a blur effect to the image input by said image input unit in correspondence with the blur state calculated by said blur state calculation unit;

    wherein the in-focal Point position designated by said in-focal point position designation unit is determined using the distance information included in the image information, based on a position which is designated by a user in an image corresponding to the image information.
