This sample shows you how to grab and display frames in realtime.
PXR800 is put into a mode where it is always grabbing another frame in
addition to the one that is currently being DMA'd. This gives you the
same result as using two buffers in software.
We do not need to set any parameters in order to implement this method.
This is the default method for the PXR800.
This method works quite well and will result in a realtime display if a
buffer can be copied to the VGA faster than the next grab can take place,
which is either 33 or 40 ms depending camera type. Almost any system today
can achieve a realtime display by using this method.
In this sample you will learn how to do the following:
1. Create a simple control window.
2. Create a video display window.
3. Initialize the PXR frame grabber.
4. Grab individual frames and display them in the video display window.
5. Grab frames and display them in realtime in the video display window.
The Visual Basic support for the PXR800 requires the following header files and libraries.
1. PXR800API.BAS
2. PXR800.BAS
3. PXRFRAME.BAS
4. IMAGINFO.BAS
5. PXR800_DISPLAY.BAS
6. PXR800.DLL
7. PXRFRAME.DLL
8. PXR800_DISPLAY.DLL
