IMAQ PCI/PXI 1424 not capturing images greater than 1024 x 1024.

[Marcpolo]

My camera provides a maximum resolution of 2048 X 2048, however I have only been able to acquire a resolution of 1024 X 1024 from my IMAQ card. If I don't reduce the camera resolution to comply with this I only have access to the upper left quadrant of the image from the IMAQ card. I only require to snap single images and was hoping that I could acquire the full resolution of the source. Does anyone know how to increase the size of the acquisition window?

Thanks in advance.

It may be done by editing the icd file for the camera. It really depends on the camera and other details.

What camera are you using? Where did the icd file come from? These details will help us answer your question.

Thanks for the response. I am using a Redlake Megaplus ES4.0 camera. I have managed to capture a 2048 x 2048 image using MAX when loading the Redlake ES 4.0 12bit.txt file, but I can only capture 1024 X 1024 images when controlling from CVI LabWindows.

I never new anything about an ICD file. There is a file Redlake ES 4.0 12bit.icd in the
C:\Program Files\National Instruments\NI-IMAQ\Data directory. How do I tell the software to use this?

My software has been setting the following configuration parameters :

Camera Mode : Continuous.
Readout Channels : Dual Channel
Binning : None
Exposure Time : 32.000
Frame Rate : 8

I have discovered that if I configure the camera using MAX and leave out the above parameter settings from my code, then I can capture the required full resolution. I'd like for my software to have the ability to configure the camera though. Am I perhaps setting the parameters in the wrong order?

The icd file is installed when you install IMAQ.

I don't know any specifics about your camera, so I will have to stick with general advice.

My suggestion would be to set up the camera in MAX the way you want it and make sure it works. You should be able to select the same settings from your program and have the same results. The order you set the options may make a difference. Once you have one setup working, try another.

It sounds like you are getting close to a solution.

I got my software working by reducing the frame rate to 4fps. It appears dual channel mode limits the frame rate. Thanks for your help Bruce.
