ABSTRACT:
A correction value determining method for each of a plurality of electro optical elements whose light intensity is controlled in accordance with a gray scale value and a correction value, the method comprising the steps described below. (a) Measuring a light intensity of the each electro optical element when the same gray scale value is specified to each of the electro optical elements. (b) Determining the correction value for each of the plurality of electro optical elements so that a light intensity after correction of one of the electro optical elements when a predetermined gray scale value is specified thereto whose light intensity measured in step (a) is a first light intensity exceeds a light intensity after correction of another one of the electro elements when the predetermined gray scale value is specified thereto whose light intensity measured in step (a) is a second light intensity which exceeds the first light intensity.
