    • A chromo-key screen method and device having a screen component with a front surface and a back surface and capable of transfusing light or other electromagnetic energy from the back surface to the front surface and one or more lights or other electromagnetic energy generators transmitting energy onto the back surface that is transfused to the front surface and transmitted from the front surface into area subject of an image capturing device, e.g. photographic or digital camera. The invention applies to chroma-key photography wherein the background screen is lighted, at least in part, from a source behind the screen. The device may include an enclosure to restrict color spilling into the foreground.
    • 一种色键屏幕方法和装置,其具有具有前表面和后表面的屏幕部件,并且能够将光或其他电磁能量从背表面输送到前表面,以及一个或多个光或其它电能发射器将能量传输到 被输送到前表面并从前表面传送到图像捕获装置的区域主体的背面,例如, 摄影或数码相机。 本发明适用于色度键摄影,其中背景屏幕至少部分地从屏幕后面的源点亮。 设备可以包括用于限制颜色溢出到前景的外壳。

    • A chromo-key screen method and device having a first chroma-key screen component with a front surface and a back surface and screen enclosure wherein the screen enclosure is capable of reflecting light from a back enclosure screen to the back surface of the chroma-key screen and transmitted to the front surface of the chroma-key screen component. Further, one or more lights or other electromagnetic energy generators transmit energy onto the back screen that is reflected to the chroma-key screen component and transfused to the front surface of the chroma-key screen and transmitted from the front surface into area subject of an image capturing device, e.g. photographic or digital camera. The invention applies to chroma-key photography wherein the background screen is lighted, at least in part, from a source behind the screen. The device may include an enclosure to restrict color spilling into the foreground. The enclosure can comprise a top and two sides, in addition to the back screen and the chroma-key or green screen.
    • 一种色键屏幕方法和装置,其具有具有前表面和背面的第一色键屏幕组件和屏幕外壳,其中屏幕外壳能够将来自后部外壳屏幕的光反射到色键的背面 屏幕并传输到色键屏幕组件的前表面。 此外,一个或多个灯或其他电磁能发生器将能量传递到背面屏幕上,该能量被反射到色度键屏幕部件并被输入到色键屏幕的前表面并从前表面传送到 图像捕获设备,例如 摄影或数码相机。 本发明适用于色度键摄影,其中背景屏幕至少部分地从屏幕后面的源点亮。 设备可以包括用于限制颜色溢出到前景的外壳。 除了背面屏幕和色键或绿色屏幕之外,外壳还可以包括顶部和两侧。
