    • There has been a problem of displacement of luminance and chromaticity among multiple screens due to a temperature change and a temporal change of a light source of the screen. The present invention provides a multi-screen display device including a plurality of image display devices, in which one master device and one or a plurality of slave devices communicable with the master device are included, each of the image display devices is provided with a DMD that modulates light of a light source, a screen that projects an image by modulated output light of the DMD, and an RGB luminance sensor that detects luminance of light from the DMD in an off-state, to output a luminance detection value, the master device is provided with a setting part that sets a luminance setting value unified among the plurality of image display devices based on a value in accordance with the luminance detection values, and each image display device is further provided with a luminance/chromaticity corrector that controls luminance/chromaticity of an image displayed on the screen based on the luminance setting value.
    • 由于温度变化和屏幕光源的时间变化,存在多个屏幕之间的亮度和色度位移的问题。 本发明提供了一种包括多个图像显示装置的多画面显示装置,其中包括一个主装置和与主装置可通信的一个或多个从装置,每个图像显示装置设置有DMD 调制光源的光,通过DMD的调制输出光投影图像的屏幕和在关闭状态下检测来自DMD的光的亮度的RGB亮度传感器,输出亮度检测值 设备具有设置部分,其基于根据亮度检测值的值来将多个图像显示设备之间的亮度设置值一体化,并且每个图像显示设备还设置有亮度/色度校正器,其控制亮度 /基于亮度设定值显示在屏幕上的图像的色度。
