Modify IMAQ attributes while grabbing images

[CertifiNATEtion]

Overview

This VI allows you to modify camera attributes while running a "continuous" grab.

Description

Many attributes cannot be changed while the camera is acquiring. To go around this, this VI checks to see if the attribute value has changed, then VI stops acquisition, modifies the attribute, and restarts the acquisition.  The attribute in the example is frame rate, but any other valid attribute can be substituted in its place. This VI requires the NI-IMAQ driver and a compliant framegrabber/camera.

Please note that if the attribute is out of range or invalid this will generate an error and stop the program. Please be aware of valid attribute ranges before modifying the attributes.

Steps to Implement or Execute Code

1. Select the appropriate camera interface
2. Run the code
3. Modify the attribute as desired.

Requirements

Software

LabVIEW, Vision Acquisiton Software or NI-IMAQ drivers
