OMI 2.3.1 Release Notes
44 OMI 2.3.1 Release Notes
The CVM6 supports one analog camera and 2 digital cameras. The analog camera is
analog port 0. The digital cameras are digital ports 0 and 1. Referring to camera 0 can
mean either analog port 0 or digital port 0, depending on the video format.
In the Image object, if your camera port is set to 0, you can select either an analog or a
digital camera format. If you want to use the second digital port (digital port 1), you must
also be using digital port 0. Once you have set up the first digital camera, follow these
steps to set up the image object to use the second digital camera:
1. Set the camera port to port 0
2. Select the video format for the digital camera you have connected to digital port 0.
This puts the image object into digital mode, so that the port numbers refer to digital
ports.
3. Set the camera port to port 1. At this point the Image object is in an invalid state,
because every camera has its own independent video format, which generally
defaults to XC-75.
4. Select the video format for the digital camera you have connected to digital port 1
At this point, the Image object is again consistent and can be used for acquisition.
Image Artifacts
Some images acquired using an MVS-8100 will exhibit extraneous fringes of dark pixels
on the right side of high-contrast dark-to-light image edges.
Setting Image Properties in Semi-Trigger and
Auto-Trigger Modes
If you want to change Image object properties while you are performing acquisition
using semi-trigger mode or auto-trigger mode, you must call StartAcquire() after
changing the properties and before calling CompleteAcquire(). If you do not call
StartAcquire(), the properties are not changed.
Unarmed Triggers in Semi-Trigger Mode Can
Cause Overrun Error
You acquire images using semi-trigger mode by following these steps:
1. You arm the trigger by calling StartAcquire().
2. The system receives a hardware trigger, causing an image to be acquired.
3. You call CompleteAcquire() to obtain the image.
