A method that takes intrinsically the horizontal field into account for calculating the current densities of the superconducting sample from magneto-optical (MO) imaging is presented. This effectively removes the "spikes" seen in the current density at the edges of the superconducting sample. The method is also found to take only twice the time of the fastest method presented so far. The effect caused by the finite thickness of the MO layer is also calculated.
