FVAL
(1)
(3)
(1) In this period camera executes trigger at next LVAL (prevents feed-through noise)
(2) Avoid trigger at FVAL transition (+/- LVAL period), as the function may randomly
switch between “ next LVAL ” and “ immediate ”.
(2)
External Trigger
+/- 1 LVAL
(3) In this period, camera executes trigger immediately ( no delay).

Starting pixel - Bayer color mosaic
The AB-1600CL is a color camera based
on a CCD sensor with a Bayer color
mosaic.
The color image reconstruction is done
in the host PC.
The color sequence in the video signal is
dependent on the scan modes.
AB-1600CL starts with GR sequence for
Full scan mode. In partial scan mode,
the starting line is user programmable
(see next section). When an odd line is
selected for the start, it starts with the
GRG sequence. When an even line is
selected, it starts with BGB sequence.

Partial Scanning
The partial scanning function employed in AM/AB-1600CL is programmable.
The height of the image can be set from 800 lines as the minimum height and expanded to 3248
lines which is the full scan image. The starting point of the scan can be set from the first line to
2448th line, when the height is set to 800 lines.
The camera has 4 memory settings for use with partial scan mode.
The following describes the programmable partial scan image.
