In this work, acquire a reference data for the liner matrix adjustment
using a DSC-F828 camera that operates normally. And saves the
data in the inside of the PC. Therefore, if the same pattern box
and the same 9 colors chart are used, it is not necessary to
perform “Get Reference Data” again. The reference data
(GodRawData.CSV) is saved in the ProgramFiles\Sony\
F828C1MATRIX holder of the C drive.
