补偿过程图像验证了响应率和偏置的非均匀性对固定图形噪声的影响。
The images of compensating process verify the influence of nonuniformity of responsibility and offset on fixed pattern noise.
图表没有考虑其他限制因素：衍射造成的低分辨率，长时间曝光带来的对固定图形噪声的敏感性。
The diagram does not consider additional constraints: decreased resolution due to diffraction and increased susceptibility to fixed pattern noise with longer exposures.
