    • PROBLEM TO BE SOLVED: To prevent deterioration in display definition even when displaying an OSD image by improving contrast while carrying out power limit control and increasing the feel of brightness in a high luminance video in a video display device carrying out light emission luminance control according to a video signal corresponding to a division area of backlight.SOLUTION: A backlight control section of a video display device determines a first luminance for LED for every division area according to a first feature quantity regarding a video indicated by a video signal after an OSD signal is synthesized for displaying in a display area corresponding to the division area. In this case, the light emission of the LED is controlled by multiplying the first luminance uniformly by a constant multiplying factor within a range having a total value of driving current of the LED be a prescribed allowable current value or less. An OSD output section 2 determines and outputs the OSD signal by using gradation data associated beforehand to a second feature quantity for the video indicated by an input video signal to be displayed in the display area for the OSD image (or an input video signal for displaying to a display area corresponding to the division area including the display area of the OSD image).
    • 要解决的问题:即使在进行功率限制控制的同时通过改善对比度显示OSD图像,并且增加根据执行发光亮度控制的视频显示装置中的高亮度视频中的亮度感觉,也可防止显示清晰度的劣化 对应于背光的分割区域的视频信号。解决方案:视频显示装置的背光控制部分根据关于OSD信号之后的视频信号所指示的视频的第一特征量,为每个划分区域确定LED的第一亮度 被合成用于在与分割区域相对应的显示区域中显示。 在这种情况下,通过在LED的驱动电流的总值为规定的容许电流值以下的范围内将第一亮度均匀地乘以恒定倍数来控制LED的发光。 OSD输出部分2通过使用预先相关于用于OSD图像的显示区域中显示的用于由输入视频信号指示的视频的第二特征量的灰度数据(或用于显示的输入视频信号)来确定并输出OSD信号 到与包括OSD图像的显示区域的划分区域对应的显示区域)。

    • PROBLEM TO BE SOLVED: To easily perform an operation to assign prescribed images to each of split screen configuration areas configuring split screens as regards an image display device which can perform image display by the split screens. SOLUTION: A conference system 10 is configured by connecting computers PC1 to PC5 to a chairperson computer PCm and a projector PR1 via a network. The chairperson computer PCm plays a role to assign prescribed images to split screen configuration areas SC11 to SC14 configuring split display screens projected by the projector PR1 on a screen SC1. A GUI device loaded on the chairperson computer PCm is configured to make a display 115 display a projector projecting operation window W500 equipped with a projection operation sub-window W600 configured of sub-windows W610 to W640 for screens corresponding to the number and arrangement of the split screen configuration areas configuring the split display screens.
