    • An image projecting apparatus that includes an illumination measuring unit that measures illumination of light illuminated on a side of the image projecting apparatus opposite a supported surface of the image projecting, an illumination calculator that calculates illumination at the projection surface based on the measured illumination, and a projection light intensity determining unit that determines luminous intensity of projection light from an image projecting unit that projects an image on the projection surface. The illumination calculator calculates illumination at the projection surface based on optical reflecting characteristics of the installation environment of the image projecting apparatus.
    • 一种图像投影设备,包括:照度测量单元,其测量照射在所述图像投影设备的与所述图像投影的被支撑表面相对的一侧的照明;照明计算器,其基于所测量的照明来计算所述投影面处的照明;以及 投影光强度确定单元,其确定从投影在投影表面上的图像的图像投影单元的投影光的发光强度。 照明计算器基于图像投影装置的安装环境的光学反射特性来计算投影面处的照明。
