Setting The Line Delay Between Colors; Averaging Horizontal Pixels; Setting The Averaging Horizontal - Dalsa PC-30-02K80-R Manual

Piranha Color Camera User's Manual
The Piranha Color is a bidirectional camera and the direction of the web movement can
be arranged in either way. If the object is passing the camera in the other direction, its
image will pass over the Blue channel first, then the Green channel, and finally the Red
channel. In order to properly construct a full color (RGB) image, the system needs to
know the direction of the movement. Another parameter, color scan direction (scd), is
used to specify the direction of web movement.

DALSA
Sets the number of lines of delay between colors that are read out
from the sensor.
ssa i
i
Line delay between colors in a range from 0-6.
To read the current line delay, use the command gcp or get ssa.
If your line rate matches the speed of the object, then the value of
the line delay will be 3.
Adjust the ssa value until you remove the red and blue halos
above and below a black on white horizontal line in order to set
the line delay.
ssa 3
Averaging reduces the pixel noise and decreases the horizontal
resolution. The charge collected in adjacent pixels is averaged
together.
sah i
i
The number of horizontal pixels to average. Available values
are 1 (factory setting) and 2.
