    • A subject captured by a camera may be affected by environmental lighting provided by nearby light sources and the sun or moon, which may cause underexposure or overexposure of the image or aesthetically displeasing color tones. Image processing and camera adjustments may mitigate some imaging problems with limited effect and introduce undesirable side effects. A lighting array may be devised to expose the subject to various types of light (e.g., white light comprising full spectrum illumination and red, green, and blue lights comprising partial spectrum illumination) to resolve lighting problems in a more effective manner. Moreover, the lighting array may be responsively controlled to adjust the subject image with respect to one or more target spectra specifying desirable colors for the subject image. The lighting array may be iteratively controlled, e.g. by a gradient descent algorithm, for incrementally adjusting parameters with respect to proximate target spectra for the image.
    • 由相机拍摄的被摄体可能会受到附近光源和太阳或月亮所提供的环境照明的影响,这可能会导致图像曝光不足或过度曝光或美观上不悦色调。 图像处理和相机调整可以以有限的效果减轻一些成像问题,并引入不期望的副作用。 可以设计照明阵列以将对象暴露于各种类型的光(例如,包括全光谱照明的白光和包括部分光谱照明的红色,绿色和蓝色光)以更有效的方式解决照明问题。 此外,可以响应地控制照明阵列以相对于为目标图像指定所需颜色的一个或多个目标光谱来调整被摄体图像。 可以迭代地控制照明阵列,例如。 通过梯度下降算法,用于相对于图像的近似目标光谱递增调整参数。
