(12) Obtain reference value

・Sensitivity reference value calculation
On condition of ISO200, using the tool lens (F5.6), the reference body is faced to the color viewer (LV13 equiv.)
with the ND filter (-6 step) being put between them. Then, the G output average value of (425 pixels × 425
pixels), which was deviated from the center by 425 pixels, is stored in the D700BSD.DAT file as the sensitivity
reference value.

・Sensitivity ratio reference value calculation

ratio reference value GR and GB are calculated and stored in the D700BSD.DAT file, based on the G/R/B output
average of (425 pixels × 425 pixels), which is deviated from the center by 425 pixels.
・Sensitivity/sensitivity ratio reference value calculation
