STINGRAY Technical Manual V2.2.0
165
The lowest possible value of ExpTime is camera-specific (see Table 60: Cam-
era-specific minimum exposure time on page 165).
Note
L
Exposure times entered via the 81Ch register are mir-
rored in the extended register, but not vice versa.
Longer integration times not only increase sensitivity,
but may also increase some unwanted effects such as
noise and pixel-to-pixel non-uniformity. Depending on
the application, these effects may limit the longest
usable integration time.
Changes in this register have immediate effect, even
when the camera is transmitting.
Extended shutter becomes inactive after writing to a
format/mode/frame rate register.
