Gradation Compression Mode
Related Setting Items:
This function compresses the bit depth of captured images to enable images containing a wide range
of pixel values to be output as a narrower set of intensity gradations.
Notes:
l
This function cannot be used when
is set to 8Bits.

When GradationCompressionMode is turned On, the
is forced to be controlled
as follows:
Mono models: Mono8
Color models - Bayer format: BayerRG8 (When ReverseX/Y is On, the flipped Bayer format is used).
In Gradation Compression Mode, the sensor first converts the analog signal into 10bits or 12bits digital
signal (= A/D conversion), and then the A/D-converted signal exceeding the compression knee point
(s) is compressed and the entire image is output as 8bits data. (Whether A/D conversion is performed
at 10 or 12 bits is based on the
setting.)
The apparent sensitivity of the uncompressed area below the knee point is x4 at 10bits and x16 at
12bits.
The maximum value of each dynamic range is 400% at 10bits and 1600% at 12bits, comparing to the
8bits output.
