12 or 8 bit depth problem

[IsaacT]

I have no available camera attributes to set.

The bit depth is set directly in the .icd, and is displayed as a acquisition parameter.

[DavidS.]

So you could probably change this parameter in the .icd file (open it with notepad for example).

[IsaacT]

As you see, the line Unsigned16bitImage is set as yes. I do not understand the fact that Max sees a valid and beautiful image, while, with the same apparent settings, Labview does not see the same image.

Could you please test this VI? It returns the Bitdepth of an image with property node.

[IsaacT]

For this vi, Bit Depth returns 0 and Image Type 3 returns 8bits, regardless of any Max setting i tried.

[DavidS.]

Could you post your .icd file?

[IsaacT]

Hi

the icd file is in the previous post, here is the full version.

Hello, IsaacT

I have Baumer SXC20. I think BitDepth number should be same with camera register bit number.

My camera register setting and icd file are following;

 camera bit:  8 -> icd file: BitDepth (8)
 camera bit: 10 -> icd file: BitDepth (10)
 camera bit: 12 -> icd file: BitDepth (12)

Camera register settings are maybe reset to factory default at Power ON/OFF unless changing option.

If you set Unsigned16BitImage option (No), IMAQ Image Type are following;

 icd file: BitDepth (8)  -> U8 image
 icd file: BitDepth (10) -> I16 image
 icd file: BitDepth (12) -> I16 image

I16 image is changed to U16 one when you choose option (Yes).

I don't know what number should be chose for BitsPerComponent. I always set it equal to BitDepth option.

Maybe you should not use constant of Image type for "Image Create".

You could put "IMAQ Property Node: Image Type" after "IMAQ Init" and next "IMAQ Create" connected "Image Tyepe".
