    • An optical system having an iris controlled in real time and a control method of amount of light thereof The optical system includes a light source, a light modulator modulating a light emitted from the light source to a certain image, a driving part controlling the light modulator to produce the certain image and outputting luminance information of the certain image, a projector projecting the certain image, a screen on which the projected image is formed, a projection iris controlling an amount of light projected from the light modulator onto the screen, and a iris controller receiving the luminance information of the certain image from the driving part and controlling the projection iris corresponding to the luminance information of the certain image. Since the opening range of the iris is controlled in real time, the contrast ratio (C/R) is improved.
    • 具有实时控制的光圈的光学系统及其光量的控制方法光学系统包括光源,调制从光源发射到某一图像的光的光调制器,控制光调制器的驱动部分 为了产生该特定图像并输出该特定图像的亮度信息,投影该特定图像的投影仪,其上形成投影图像的屏幕,将从光调制器投影的光量控制在屏幕上的投影光圈,以及 光圈控制器从驱动部分接收特定图像的亮度信息,并控制与特定图像的亮度信息相对应的投影光圈。 由于实时控制虹膜的开口范围,因此对比度(C / R)提高。
