Camera Type Selection
This scrolling list panel lists the “standard” camera types that the
Allen–Bradley Company supports, along with any non–standard camera
types that have been user–configured in the
Acquisition Editor panel. To
select a camera type for the current camera number, highlight the camera
type by picking its name.
You can edit various timing parameters for the highlighted camera type by
picking the
button and accessing the corresponding Camera
Type edit panel. (For details about this panel, refer to the Camera Type:
Selection and Editing section on page 3–33.)
Horizontal Resolution Selection
These are the two “ H.Res ”, or horizontal resolutions:
•
Full –– This selects the full horizontal camera resolution equal to the
Acq. Pixels setting in the Camera Type panel (typically 512 pixels).
•
Half –– This selects one half of the full horizontal camera resolution
(typically 256 pixels –– every other pixel is acquired).
Field Selections
The “ Fields ” selections are 1, First ; 1, Same ; and 2 . Here is what they
signify:
•
1, First –– This causes the system to acquire the first field (odd or even)
to become available after any given trigger signal. The vertical resolution
is one–half the
Acq. Lines (1/2 Lines) setting in the Camera Type
panel (typically 240 lines).
•
*1, Same –– This causes the system to acquire field 0 only. The vertical
resolution is one–half the
Acq. Lines (1/2 Lines) setting in the Camera
Type panel (typically 240 lines).
•
*2 –– This causes the system to acquire the image with full vertical
resolution (typically 480 lines).
*These selections are significant only when an interlaced camera is used.
