3.8.13 Vertical
Mode
3.8.13.1 Set Vertical Mode (
‘svm’
)
The
‘svm’
command configures the camera to operate in either the
normal, windowing or binning modes. The normal mode turns off both
windowing and binning. In the windowing mode of operation, the
vertical area of interest is defined by the
‘svw’
command. Setting the
binning mode instructs the camera to perform vertical binning on all
incoming pixels. During this process, the camera sums each pixel of
adjacent lines in a frame and then delivers the average value to the
Camera Link interface. Therefore, in this mode, the number of lines
per frame is reduced by one half. Using this command increases the
effective frame rate of the camera and also reduces the exposure time.
Syntax:
svm <n|w|b>
Parameter:
n
Normal mode
w
Enables horizontal window.
b
Enables horizontal binning.
Example:
svm w
Enables vertical window.
Notes:
In the windowing mode, it is necessary to adjust the
number of active lines per frame in the frame grabber
to the value of y2 – y1 + 1, where y1 and y2
represent the starting and ending lines, respectively,
as defined by the
‘svw’
command.
In the binning mode, it is necessary to adjust the
number of active lines per frame in the frame grabber
to the value of n/2, where n represents the maximum
number of active lines in a frame.
3.8.13.2 Get Vertical Mode (
‘gvm’
)
The
‘gvm’
command returns the current vertical mode setting.
Syntax:
gvb
Response:
n|w|b
Example:
gvm
User enters command.
w
Camera responds with current setting.
