A Multi-Step Gain Adjusting Strategy (MSGAS) of space camera was proposed  which was used to get higher SNR (Signal-Noise Rate) image. When the space camera working in poor light condition  the CCD signal was so weak that it's difficult to get a clear image  to reduce the quantization noise and improve the SNR  we must amplify the CCD signal first and then quantize. The MSGAS was achieved by adjusting the gain of the CCD (Charge Couple Device) signal processor step by step  the upper limit and lower limit were set  if the MDN (Mean Digital Number) of a fixed length image data was not between the lower and upper limit  the gain was adjusted step by step. In the experiment  the upper limit  lower limit and the step were set  and the result of the experiment showed that MSGAS was robust and SNR was improved from 28 to 39. 2009 IEEE.
