Imaging Source camera Error 0xBFF69037 "No decoder available for selected pixel format"

[petawatt]

Hi,

I rpucrchased an Imaging Source DMK 23U618 CCD USB 3.0 camera and installed the drivers correctly. However, when I tried tio get NI MAX/ LabVIEW to recognize my camera as monochrome, it threw at me this error: Error 0xBFF69037 "No decoder available for selected pixel format".

I tried selecting Grayscale U16 and  Grayscale U8 but everytime I get this error.

Does anyone know how I can get rid of this erro?

Any help would be appreviated! 🙂

Since this camera is not "USB3 Vision" but instead is providing a DirectShow filter that IMAQdx is connecting to, it is limited to the interfaces provided. This means it is limited to a color image. You selected you wanted the output image as Mono instead of Auto or RGB. IMAQdx does not provide a down conversion within the driver itself to monochrome from a color image. You can do a cast using the Vision library in code/LabVIEW.

Thanks very much, this helped a lot.

@BlueCheese, Is there any way for me to convert the images from RGB to grayscale while I'm performing a Grab from a camera?

Within LabVIEW/C code or Vision Builder AI, yes, but not from MAX. The driver doesn't perform this conversion itself.

BlueCheese, I attached two VIs; one of them grabs from a camera and the other on converts an RBG to grayscale from a file path. How can I make it to convert the data straight from the camera to grayscale and display it in real time? In other words, how can I get rid of the file path and instead substitute a Grab vi?
