1. An image processing apparatus for processing an image sensed by an image sensing unit which includes an optical system and an image sensing element for converting a subject image formed by said optical system into an electric signal, the image processing apparatus comprising:

  • a storage unit adapted to store relative positional information of an optical axis of said optical system and a reference point of an effective range of said image sensing element and a function representing transmission characteristics of said optical system in advance;

    a correction value calculation unit adapted to calculate a correction value for correcting an image sensed by said image sensing unit using the relative positional information and the function; and

    an image correction unit adapted to correct the sensed image based upon the correction value.
