High SNR mode (High Signal Noise Ratio)
With High SNR mode enabled the camera internally grabs GrabCount images
and outputs a single averaged image.
Register Name Field Bit Description
0xF1000520 HIGH_SNR Presence_Inq [0] Indicates presence of this feature
(read only)
--- [1..5] Reserved
ON_OFF [6] High SNR mode on/off
High SNR mode on requires a
minimum GrabCount value of 2.
Set grab count and activation of
HighSNR in one single write
access.
--- [7..22] Reserved
GrabCount [23..31] Enter number of images
Permissible values are:
2, 4, 8, 16, 32, 64, 128, 256
If you enter a non-expected
value, the firmware will round
down to the first permitted value.

write 128 to the register.

Note

• The camera must be idle to toggle this feature on/off.
Idle means: no image acquisition, no trigger.
• Set grab count and activation of HighSNR in one single
write access.
Note

• Writing to the HIGH_SNR register while capture is
active will accept the new value, but it will not become
active. Even subsequently stopping and starting acqui-
sition will not change this.
• Writing the HIGH_SNR register is only effective if done
while the camera is not actively acquiring.
