    • A correction value for luminance correction is determined by: measuring a luminance value of each display element by displaying a first image including luminance unevenness caused by characteristic differences among the display elements and characteristic differences among modulation circuits, and calculating a first luminance value serving as a representative luminance value of the display elements for each of the modulation circuits; measuring the luminance value of each of the display elements by displaying a second image in which the luminance unevenness caused by characteristic differences among the modulation circuits is smaller than that of the first image, and calculating a second luminance value serving as a representative luminance value of the display elements for each of the modulation circuits; and calculating a correction value corresponding to each modulation circuit using a value obtained by dividing the first luminance value by the second luminance value.
    • 通过以下方式确定亮度校正的校正值:通过显示包括由显示元件之间的特征差异引起的亮度不均匀的第一图像和调制电路之间的特性差来测量每个显示元件的亮度值,并且计算用作 每个调制电路的显示元件的代表亮度值; 通过显示其中由调制电路之间的特性差导致的亮度不均匀性小于第一图像的亮度不均匀的第二图像来测量每个显示元件的亮度值,并且计算用作代表亮度值的第二亮度值 每个调制电路的显示元件; 以及使用通过将所述第一亮度值除以所述第二亮度值而获得的值来计算与每个调制电路相对应的校正值。

    • An image display apparatus has a correction unit that performs a correction process on image signals so as to suppress luminance fluctuation caused by capacitive coupling between adjacent column wirings. The correction unit includes: a correction value generation unit that determines a correction value for a pixel to be corrected on the basis of a combination of a signal value of the pixel to be corrected and signal values of adjacent pixels which are on a column wiring next to a column wiring on which the pixel to be corrected is, and on the basis of a position of the pixel to be corrected in a column direction; and a correction operation unit that corrects a signal of the pixel to be corrected using the correction value generated by the correction value generation unit.
    • 图像显示装置具有对图像信号执行校正处理的校正单元,以便抑制由相邻列布线之间的电容耦合引起的亮度波动。 校正单元包括:校正值生成单元,其基于要校正的像素的信号值和下一列列线上的相邻像素的信号值的组合来确定要校正的像素的校正值 到要校正的像素的列布线,并且基于要在列方向上被校正的像素的位置; 以及校正操作单元,其使用由校正值生成单元生成的校正值来校正要校正的像素的信号。
