Hello 
I am using Imaqe Acquisition ToolBox to get image from a  
camera which is using 'winvideo'.
Now when I use the AMCAP.exe which is bundled along with 
the Image Acuisition ToolBox, I see that it utilizes very 
little CPU. i.e if I open Task Manager and check the 
Processes, then AMCAP will be utilizing about 2% CPU. 
Whereas if I use Matlab's Preview function and then check 
the CPU usage I see that its consuming about 50% CPU power.
Why is there so much difference. 
Does AMCAP utilize any other technologies like DIRECTX?

This question arose, since I observed after using Preview
(), that my computer starts gets heated up and the fan 
speed increases to cool the CPU.
