We present a correction method for the density of states (DOS) obtained from the generalized ensemble simulations. The DOS is proportionally corrected to match the exact values and/or good approximations known for the system. We demonstrate the validity of the method by applying it to the DOS of 2D Potts model calculated from various generalized ensemble simulations. It is shown that the root-mean-square error of the DOS is reduced by ~50% or more without additional heavy calculations.
