One-Shot
The camera can record an image by setting the OneShot bit in the 61Ch reg-
ister. This bit is automatically cleared after the image is captured. If the cam-
era is placed in Iso_Enable mode (see Chapter ISO_Enable / Free-Run on page
157), this flag is ignored.
If OneShot mode is combined with the external trigger, the OneShot com-
mand is used to arm it. The following screenshot shows the sequence of com-
mands needed to put the camera into this mode. It enables the camera to
grab exactly one image with an external trigger edge.
If there is no trigger impulse after the camera has been armed, OneShot can
be cancelled by clearing the bit.
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.
