Abstract: PURPOSE: A contrast-sensitivity measuring method is provided to discriminate a periodical pattern by an inspector with respect to each spatial frequency of a periodical pattern. CONSTITUTION: A periodical pattern is displayed on a monitor. A spatial frequency of the displayed pattern is increased and a first threshold contrast in a corresponding spatial frequency is searched and set. The spatial frequency of the displayed pattern is reduced and a second threshold contrast in a corresponding spatial frequency is searched and set. The first threshold contrast is set as a final threshold with respect to a spatial frequency having the same first and second threshold contrasts. A third threshold contrast is search and set with respect to a spatial frequency having first and second different threshold contrasts. It is judged whether a repeated contrast among the first, second, and third threshold contrasts is present. The final threshold contrast is determined according to the judgment result.
