Image Acquisition Parameters
3–3
The Camera setup panel contains a scrolling list panel, several parameter
selection boxes, and several buttons, which are described briefly as follows:
•
Camera Type –– The Camera Type scrolling list enables you to select a
camera type (such as 2801–YF) that pertains only to the selected camera
number (this number corresponds to the camera port number on the
CVIM2 module front panel).
•
Edit Camera Type –– The button accesses the Camera
Type edit panel for the camera type highlighted in the adjacent Camera
Type scrolling list. The Camera Type edit panel enables you to edit
various timing parameters for the highlighted camera type.
•
H.Res –– This box selects either the full horizontal resolution capability
of the camera in use, or just half of that resolution capability.
•
Fields –– This box selects one vertical field for half vertical resolution, or
two vertical fields for full vertical resolution.
•
Focus Trigger –– This field selects either the internal trigger source or an
external trigger source for focus operations. It applies to the camera setup
operation only.
•
Rate Per Minute –– This field selects a trigger rate per minute when the
auto/internal trigger source is selected as the focus trigger. It applies to
the camera setup operation only.
•
Focus Source –– This field assigns a discrete input for the trigger signal
when the external trigger source is selected. It applies to the camera setup
operation only.
•
Shutter Speed –– This field is active only when a frame reset camera
type (such as the 2801–YE) is selected. It accesses the calculator that is
used to set the frame reset camera’s shutter speed.
•
Focus Strobe –– This assigns a discrete output for the strobe signal. It
applies to the camera setup operation only.
•
Focus –– The button starts the focus function, which captures
continuous camera images and enables the user to perform camera and
lighting adjustments.
•
Light Reference –– The button accesses the light
reference adjustment panel, which can be used to maximize the contrast
in the image.
•
Light Probe –– The button accesses the light probe setup
function, which can be used to set up lighting compensation for the
inspection tools.
•
Calibrate –– The button accesses the calibrate function, which
which enables you to calibrate the image field to inches or centimeters
(“world units”) and perform measurements, such as linear gaging, in
those units.
•
Done –– The button exits the Camera panel and returns to the
Acquisition Editor panel.
The remainder of this section describes these functions, features, and
parameters in detail.
