①Introduction (Continued)
    Each image can be processed manually and carefully in similar way to non-solar observation. However, every image must, first, be processed automatically without any parameter adjustments in order to determine when and where remarkable phenomena occurred.
    Initial restoration procedure in solar observation, therefore, requires the ability with;
1. Good performance of restoration for complicated structures, especially  for diffuse features.
2.  single set of parameters which are independent from the solar activities.
3. less computational time.
