The storage unit 6 has the processing parameter table 6a shown in FIG. 2, and has a plurality of processing parameter patterns combining various processing parameters calculated so as to obtain an optimum processing result for each imaging region. I remember. This will be described in detail with reference to FIG. 2. In the processing parameter table 6a, each processing parameter pattern stores the value of the processing parameter in each image processing for each imaging region. For example, the processing parameter pattern “ABC
