在该项目中，测试了A.Foi等人的噪声模型，并从结果中观察到噪声参数对温度，ISO设置（模拟增益）和曝光时间（快门时间）的依赖性。参数噪声模型被证明是适合这类研究。ISO设置对噪声的影响比图像传感器的温度或快门时间大得多。
In this project work noise model by A.Foi et al. was tested and from results dependence of noise parameter on temperature, ISO setting (analog gain) and exposure time (shutter time) was observed. Parametric noise model was proven to be suitable for this kind of research. ISO setting was found to have much larger effect on noise than temperature of an image sensor or shutter time.
