摘要：
Exemplary embodiments of the present invention provide a light propagation characteristic control apparatus which extends the light-intensity dynamic range and the number of levels, and are suited for enhancing image quality and reducing the size and generation time of tables. Exemplary embodiments provide a projection display apparatus that tentatively decides a transmissivity T2 of each pixel of a color-modulation light valve depending upon HDR display data, and decides a transmissivity T1 of each pixel of an intensity-modulation light valve depending upon a tentatively decided transmissivity T2 and the HDR display data, and a control value of each pixel of the intensity-modulation light valve depending upon a decided transmissivity T1. Depending upon a decided transmissivity T1 and the HDR display data, transmissivity T2 is decided of each pixel of the color-modulation light valve. Depending upon a decided transmissivity T2, a control value is decided of each pixel of the color-modulation light valve.
摘要（中）：

本发明的示例性实施例提供了一种光传播特性控制装置，其延伸光强度动态范围和级数，并且适于增强图像质量并减小表的尺寸和生成时间。 示例性实施例提供了一种投影显示装置，其暂时地根据HDR显示数据确定调色光阀的每个像素的透射率T 2，并且根据暂时确定强度调制光阀的每个像素的透射率T 1 决定透射率T 2和HDR显示数据，以及根据所确定的透射率T 1的强度调制光阀的每个像素的控制值。 根据决定的透射率T 1和HDR显示数据，由调色光阀的每个像素决定透射率T 2。 根据决定的透射率T 2，决定调色光阀的各像素的控制值。
