Conversion Gain
A Higher Conversion Gain means higher sensitivity, as one signal electron can
be more
easily detected. The high-CG sensor shows a very clear responsivity
advantage; however, the trade off is clearly seen in the much lower full-well
capacity as the sensor’s linear range ends at a much lower exposure.
Low conversion gain (
LCG
) for large charge handling capacity in bright scenes.
High Conversion Gain (
HCG
) mode with increased sensitivity and low read noise
for lowlight scenes, providing tremendous benefit for real time imaging.
The
LCG
mode is comparable to the old NO GAIN, while the
HCG
mode is
comparible to high gain is
HCG
. The trade off is the effective-lower readout noise
and doubling the signal output, while halving the dynamic range.
Use the appropriate mode to either push the sensitivity (decreases the dynamic
range), or increase the dynamics range (decreases the sensitivity). The choice
depends upon the object being images. Experiment.
The following images illustrate the benefits of using
HCG
. In both images the
exposure time was the same. The left image had
LCG
checked, while the right
image have the
HCG
checked.
