摘要： Brightness expression without solid white pattern is enabled, and video expression with an improved black level is achieved. A distortion module (5) reduces the luminance of a backlight source according to the histogram of the video signal so that the contrast may be a predetermined target one. A configuration design unit (13) sets the gain according to the luminance level (BLreduced) of the backlight source selected by the distortion module (5). When setting the gain, the luminance level (BLref) for reference of the backlight source preset according to the video feature value is referenced. If the video feature value meets a predetermined condition, the input video signal is always amplified with the gain. If not, depending on the relation between the BLreduced and the BLref, the input video signal is amplified or not.
摘要翻译：没有固体白色图案的亮度表达被启用，并且实现了具有改进的黑色电平的视频表达。失真模块（5）根据视频信号的直方图降低背光源的亮度，使得对比度可以是预定的目标对象。配置设计单元（13）根据由失真模块（5）选择的背光源的亮度水平（BL减去）设置增益。在设定增益的情况下，参照根据视频特征值预设的背光源的基准亮度水平（BLref）。如果视频特征值满足预定条件，则输入视频信号总是以增益放大。如果不是，取决于BLreduced和BLref之间的关系，输入视频信号被放大或不被放大。

摘要： In general, when a user views an image displayed on a display apparatus, visual environments, such as ambient brightness, a distance from the user to the display apparatus and so on, may disadvantageously cause the image displayed on the display apparatus to become difficult to view. Moreover, it is complicated and troublesome for the user to enter information of ambient light amount and others when setting a picture quality. An image display apparatus holds both question constituent information related to visual environments and choice information serving as answers to questions constituted by the question constituent information, and further holds a plurality of picture quality control rules suitable for visual environments assumed in accordance with the choice information serving as the answers. When sensing a power-up, the image display apparatus outputs the questions; acquires result information that is choices serving as answers from the user to those questions and that is used to acquire the picture quality control rules; and controls the picture quality in accordance with the picture quality control rules acquired in accordance with the result information.
