在本文中,我们描述了测试数码相机中颜色传感器的线性度和估计光谱灵敏度的方法。我们的分析基于柯达 DCS-200 和 DCS-420 数码相机对校准光谱输入的响应。我们使用这些数据构建数码相机的线性模型,并通过将实际相机响应与校准光谱输入与线性模型预测的输出值进行比较来验证它。
In this paper we describe methods for testing the linearity and estimating the spectral sensitivities of color sensors in digital cameras. We base our analysis on the response of the Kodak DCS-200 and DCS-420 digital cameras to calibrated spectral input. We use this data to build a linear model of the digital camera and verify it by comparing the actual camera response to calibrated spectral input to output values predicted by the linear model.
