    • 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.
    • 一种校正特性确定装置,用于(a)通过使用转换矩阵将表示液晶面板的发光条件的测量数据转换为三原色的亮度数据,以及(b)根据转换来确定校正特性 (a)得到的结果。 在某些示例性实施例中,设备可以设置指示图像信号的灰度(或灰度)比例值与目标输出亮度之间的关系的目标曲线。 可以通过在某些示例性实施例中从最低目标输出亮度减去实际亮度值来设置调整参数。 可以根据至少基于调整参数调整的目标曲线,在未校正的灰度值和校正灰度值之间确定关系。
