Visible+IR in black and white mode

Hello, 

I am using IMX8M plus for my application development,

I have an 2MP RGB sensor with dual band pass filter lens (Visible+NIR 940nm), it outputs 12bit RAW RGB. Using IMX8M plus ISP, I need to fuse both visible and infrared (IR) data and convert into a single black and white (grayscale) image which can enhance imaging capabilities.

Is this supported in the IMX8Mplus ISP? how can I achieve this, which API should I use it?

Regards,

Thanks, let me reach out to the local representative for the support on the tooling.

Re: Visible+IR in black and white mode

I don't have tuning tool so I didn't use tuning server before, since you need to request this tool, you can test after you get this tools, as my understanding, after you build the ISP sdk, you would get the library files, then you can use the tuning server by these library files

Re: Visible+IR in black and white mode

Yes, the tunning tool is required and I can request the local representative.

but, Is that for tunning server I need to request for, I need to convert this onchip an not offline (tunning client)?

Re: Visible+IR in black and white mode

you should use tuning tool to support this,  for tuning tool,  you need contact local representative to get it 

Re: Visible+IR in black and white mode

I went through the reference document, basically there are two ways to tune to grayscale Image, tunning client is straight forward process with the documentation, 

I would be more interested to use tunning server i.e, to run directly on IMX8M plus , Is tunning client required as well?

or tunning server alone is sufficient, then with this 3 commands, can I convert into grayscaleImage?

Re: Visible+IR in black and white mode

I attached the AN for your reference, you can ty to use the tools to tune the ISP to check if it has the feature you need

Re: Visible+IR in black and white mode

I understand this is not tested and guaranteed,

but is there an API available or any alternate solution available to convert into an grayscale Image, I can test this.

Re: Visible+IR in black and white mode

this is my another case, I confirmed that we couldn't guarantee this because we don't test this yet
