A correction characteristic determining device for (a) converting measured data, indicative of an emission condition of a liquid crystal panel, into brightness data of three primary colors by using a conversion matrix, and (b) determining the correction characteristic in accordance with a conversion result obtained by (a). The device may in certain example embodiments may set a target curve indicative of a relationship between a grey (or gray) scale value of an image signal and target output brightness. An adjustment parameter may be set by subtracting an actual brightness value from a lowest target output brightness in certain example embodiments. A relationship may be determined between a non-corrected grey scale value and a corrected grey scale value in accordance with the target curve that has been adjusted based at least on the adjustment parameter.
