PIKE Technical Manual V4.0.0

The lowest possible value of ExpTime is camera-specific (see Table 72: Cam-
era-specific minimum exposure time on page 181).
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.
