    • Various embodiments relate to an apparatus for controlling a lighting device. A light control circuit can use a controlled lighting sequence control and drive viewed sections of a lighting device to display chroma key color or emit infrared light, while driving other unviewed portions of the lighting device to display ambient and incident lighting. The viewed and unviewed lighting sections can be based on the field of vision of an image capture device and can change in relation to movements of the image capture device. A sensor can make measurements to determine the field of vision of the image capture device and can be used to generate or modify the controlled lighting sequence. An image processing circuit can generate a composite image using the chroma key while maintaining the subjects that are captured using ambient and incident lighting.
    • 各种实施例涉及一种用于控制照明装置的装置。 光控制电路可以使用照明装置的受控照明顺序控制和驱动观看部分来显示色度键颜色或发出红外光,同时驱动照明装置的其他未观看部分以显示环境和入射照明。 观看和未被观察的照明部分可以基于图像捕获装置的视野,并且可以相对于图像拍摄装置的移动而改变。 传感器可进行测量以确定图像捕获装置的视野,并可用于生成或修改受控照明序列。 图像处理电路可以使用色度键生成合成图像,同时保持使用环境和入射照明捕获的被摄体。
