Want to set my camera output 16bit greyscale

Hi All,

I am using a Guppy pro F-031b camera.

I want to let it output 16bits greyscale picture, so

1st .I set my camera as Format_7 Mode_6(partial image and mono 16) by writing the register. 

2nd .Then I set the IMAQ image type as grayscale(U16).

But I still got a 8bit picture.  What shall I do to solve this problem?

This is the first time I work with Labview. Any help is appreciate.

Thank you,

Best,

Wen
