    • A light emitting display device, an electronic apparatus, and a device and a program for correcting burn-in are provided to perform an exact correction operation by performing a gamma correction on grayness values of overall pixels in order to reduce estimation deterioration amounts. A deterioration amount difference producing unit(313) produces a deterioration amount difference between corrected pixels and reference pixels during a first light emitting period. A correction amount producing unit(317) produces correction amounts, which are required for correcting the deterioration amount difference during a second light emitting period, based on estimation deterioration amounts. A deterioration amount difference correction unit(319) corrects grayness values. A gamma conversion unit(335) performs a gamma conversion on the corrected grayness values and supplies the converted grayness values to a display panel. A deterioration amount producing unit(331) receives the grayness values and produces real deterioration amounts. An estimation error detector(333) detects error amounts and adjusts the gamma conversion unit so as to prevent the detected error.
    • 提供发光显示装置,电子设备以及用于校正老化的装置和程序,以通过对整个像素的灰度值执行伽马校正来执行精确的校正操作,以便减少估计恶化量。 劣化量差产生单元(313)在第一发光周期期间产生校正像素和参考像素之间的劣化量差。 校正量产生单元(317)基于估计劣化量产生校正在第二发光周期期间的劣化量差所需的校正量。 劣化量差异校正单元(319)校正灰度值。 伽马转换单元(335)对校正的灰度值执行伽马转换,并将转换的灰度值提供给显示面板。 劣化量产生单元(331)接收灰度值并产生实际的劣化量。 估计误差检测器(333)检测误差量并调整伽马转换单元以防止检测到的误差。
