(3) Sensitivity adjustment
Under condition of ISO200 and ISO800, the camera is faced to the color viewer (LV13 equiv.) with ND filter (-6
steps) being put between them. Using the tool lens (F5.6), the adjustment is made by changing the ampgain so
that G output can fall in the standard range. The gain value is adjusted so that the G output average value (Average
of Gr/Gb) of (425×425 pixels), which was deviated from the center by 425 pixels, can reach the target output
level. By this sensitivity adjustment, the gain difference adjustment among channels is automatically made.
Next, under condition of ISO6400, the camera is faced to the color viewer (LV13 equiv.) with ND filter (-8
steps) being put between them. Using the tool lens (F5.6), perform the same adjustment as the above.
