Property Value

Implements

Sets or gets the exposure time in milliseconds. The special value zero indicates to use the shortest time that the camera supports.

For strobed acquisitions, this value is the duration of the strobe pulse. To find the pulse duration of your strobe, see the strobe light’s specifications. Note that this function is used to let the acquisition software know the duration of the strobe pulse, not to set the duration of the strobe pulse.

To determine the exposure time for Cognex CDC cameras, see How to Choose a CDC Shutter Mode.

If you are using a FireWire (IEEE 1394DCAM) camera, the exposure value may be an absolute time in milliseconds or a a register value. Check with the documentation supplied with your camera to determine whether your camera supports absolute exposure times. In cases where the register value can be multiplied by a constant to obtain and absolute exposure, the camera's CCF provides the necessary information to use absolute values. In all other case, you must use the raw register value.

You can use the DCAM Doctor application included in your VisionPro distribution to learn about the properties of your FireWire camera.
