The present invention discloses a method for tilt correction. A plurality of reference values for DAC are imported at the beginning and then PI/PO corresponding to each of the reference values for DAC is produced. By the usage of a specified function plot Constructed of reference values for DAC and the corresponding values of PI/PO, the minimum value of the PI/PO in the specified function plot is sorted and the reference value for DAC corresponding to the minimum value of the PI/PO stands for the optimum compensated value for tilt.
