Coefficients W 0 , W 1 and W 2 to be used in finding a new quadratic function f 2 (W) indicating dependence of a distortion component on an coefficient by the least square method are obtained as values that satisfy a relational expression f 1 (W 0 ) = f 1 (W 2 ) = f 1 (W 1 ) + P (where P is a true value) on the basis of a quadratic function f 1 (W) indicating unupdated distortion component coefficient dependence. |
