The following shading correction modes are available on the camera.
■ FlatShading
Correction is performed using the area of the screen with the highest brightness level as the
reference, and adjusting the brightness levels of the other areas to match this level.
■ ColorShading (SP-12401C-PGE only)
R-channel and B-channel properties are adjusted to using the G-channel shading properties
as a reference.

• For FlatShading and ColorShading, the maximum amount of correction gain for all pixels is

increased to more than 8 times the amount of gain from before correction.)
• If the area in the screen with the highest brightness level is 175 LSB or less (during 10-bit
video output), proper correction is not possible.
