After operating on orbit for certain periods, natural degradation of CCD will result in the issue that the image SNR begins to apparently decreasing. To increase image SNR, one of the feasible ways is to increase CCD integration time. However, more Gaussian-like thermal noise, which could blur the image and even decrease the compression ratio of onboard lossless compression, will be added into the...
