choose to acquire only a portion  
of the image using the onboard  
programmable ROI feature. You can configure the size of the  
acquired image using Measurement & Automation Explorer, or use  
Real-Time Color Conversion  
Real-time color conversion is especially useful for high-speed color the ROI tools in the NI-IMAQ driver software to transfer only a  
matching in industrial or scientific applications, even in varying  
illumination. An example of HSL in action is using color to inspect  
the presence of an object even though there are shadows and/or  
reflections. Lighting variations do not affect the image (hue). Use  
the powerful color matching functions in IMAQ Vision to locate  
objects quickly and accurately with the onboard HSL conversion.  
subset of the image to PC memory for processing. Partial image  
scanning results in fewer pixels to process. For example, using  
partial image scanning, you can reduce a 640 by 480 image to a  
400 by 400 image and increase your processing speed by  
operating on 48 percent fewer pixels.  
Color Image Acquisition Performance Gains  
with Onboard Decimation  
Easy-to-Use Driver Software  
National Instruments NI-IMAQ driver level software offers the  
most comprehensive software interface for image acquisition.  
NI 1411 Series devices are shipped with the NI-IMAQ image  
acquisition driver software and National Instruments  
Measurement & Automation Explorer for easy configuration of  
NTSC and PAL color cameras. Using NI-IMAQ, you can quickly and  
easily start your application without having to program at the  
Onboard decimation also provides image acquisition and  
processing performance gains by allowing onboard scaling or  
decimating of the image without using the PC processor. Onboard  
decimation scales the image by removing every second, fourth, or  
eighth pixel (powers of two only). By reducing the number of pixels  
(decimation) on the IMAQ board, the system has fewer pixels to  
process with the PC processor. If you remove every other pixel  
register level. You can program your image acquisition application using onboard decimation, the image size decreases by  
in LabVIEW, LabWindows/CVI, and Measurement Studio. 50 percent, which speeds up your processing.
