Shading Correction
The shading correction is a function that corrects non-uniformity (i.e., shading) in the amount
of light generated by the lens and lighting equipment.
The following shading correction modes are available on the camera
。
SW-4000T-10GE
— 32 —
■
Flat shading correction
Correct so that the part with the highest luminance level in the screen is taken as the
reference and the other part is adjusted to this luminance level.
■
Color shading correction
R-channel and B-channel properties are adjusted by using the G-channel shading properties
as a reference.
Pre-correction
Post-correction
■
To perform the shading function
The function is turned ON/OFF via serial communication. This function is not dependent on
the operation mode, but is effective when used during actual use.
◇
You can also save the setting and have it applied whenever the power is subsequently turned
on. For details on saving the setting, see “Step 7: Saving the Settings”
・
For Flat Shading and Color Shading, the maximum correction gain amount is limited to 8 times
the gain amount before correction in all pixels.
・
If the highest luminance level in the image is 175 LSB (10 bit image output) or less, it can not
be corrected correctly.
Black Level Correction
Black level correction is a function for adjusting the setup level.
When this function is used, the following is performed for the gain mode setting.
Digital All
-
133
~+
255 (LSB@12bit)
Digital Red
-
64
~ +
64 (LSB@12bit)
Digital Blue
-
64
~ +
64 (LSB@12bit)
◇
Complete correction may not be possible depending on the optical system and light source
you are using.
◇
Data based on corrections performed under factory conditions is stored for this function.
