Controlling image capture
9.9 Sequence mode
Gen ally all AVT Marlin cameras enable certain image settings to be modified on the fly, e.g.
gain and shutter can be changed by the host computer by writing into the gain and shutter
er even while the camera is running. An uncertainty of one or two images remains because
lly the host does not know (especially with external trigger) when the next image will

Examples:
For a sequence of images, each image can be recorded with a different shutter or gain to obtain
different brightness effects.
The image area (AOI) of a sequence of images can automatically be modified, thus creating a
panning or sequential split screen effect.
The following registers can be modified to affect the individual steps of the sequence.

Sequence mode is a different concept where the camera holds a set of different image parameters
sequence of images. The parameter set is stored volatile in the camera for each image to be
ed. This sequence of parameter sets is simply called a sequence. The advantage is that the
a can easily synchronize this parameter set with the images so that no uncertainty can

 Sequence mode requires special care if changing image size and frame rate related
parameters. This is because these changes not only affect settings in the camera but also
require corresponding settings in the receiving software in the PC. Incorrect handling
may lead to image corruption or loss of subsequent images. Please ask for detailed
support when you want to use this feature.
