RE: FLIR camera bit depth configuration with ADSpinnaker

Hi Florian,

 

You have 2 problems.  This is the first one:

 

Ø  Unfortunately, I’m getting an error message if GC_PixelCoding enum is set to Mono12Packet:
2021/06/10 16:39:01.025 ADSpinnaker:grabImage: unsupported pixel format=0xb

 

Setting GC_PixelCoding to Mono12Packed does not actually cause the ADC to operate in 12-bit mode.  It just tells the camera to send the data with 2 12-bit pixel values packed into 3 bytes, to decrease the required bandwidth.  You are getting an error because when you select Mono12Packed you must also set the ConvertPixelFormat PV to Mono16 so that the 12-bit data is expanded to 16-bits in ADSpinnaker, which areaDetector can understand.

 

The second problem is with the data being 10-bit rather than 12-bit.  This is because you need to set a camera-specific GenICam feature to select the desired ADC bit depth.  That PV is called GC_AdcBitDepth, and you will find it on one of the camera-specific OPI screens.

Subject: FLIR camera bit depth configuration with ADSpinnaker

 

Hello,

Sorry if it’s not directly related to areaDetector/EPICS but I have some issues when I try to configure the acquisition with Flir/PointGrey cameras, I’m using the ADSpinnaker module and I have GigE cameras (BFLY-PGE-23S6M) that should support 12 bits depth images according to the FLIR datasheet. Unfortunately, I’m getting an error message if GC_PixelCoding enum is set to Mono12Packet:

2021/06/10 16:39:01.025 ADSpinnaker:grabImage: unsupported pixel format=0xb

If GC_PixelCoding is set to 16bits instead, the acquisition works but the images remain at 10 bit depth.

Did I miss something during the configuration? How I can configure my cameras to work with 12 bit depth?

Thanks for your help.
Cheers.

Florian
