5.1.2

Line Scan Mode (L-cameras only)

Very high frame rates can be obtained in the Line Scan mode (see also Table 5.2). In this mode
the L-cameras are a cost-effective replacement of line scan cameras. The number of rows and
their position can be set by the normal ROI settings. More advanced settings as Decimation or
MROI are supported in this mode. The resulting number of rows must not exceed 4 in the Line
Scan mode.

Frame Combine

In the FrameCombine mode the camera combines n (n=NrOfFrames) into one frame. In some
cases it consumes less CPU power to process these combined frames than to process every
frame individually.

There exist possibilities to transmit the combined frame even if there is not enough data to fill
it.

FrameCombineTimeout

A timeout can be specified after which the combined frame will be

transmitted, regardless if there was enough data to fill it. The timeout counter is reset
after each frame and counts until a new trigger has been detected or until the timeout is
reached.

A FrameCombineTimeout value of 0 disables the FrameCombine timeout fea-
ture.

ForceTimeout

The transmission of the combined frame is forced by writing to the

ForceTimeout property.

When the FrameCombine is aborted, then the remaining data in the combined frame will be
filled with filler data: the first two pixels of every filler row have the values 0xBB (decimal 187)
and 0x44 (decimal 68). The remaining pixels of the filler rows have the value 0.
