Hi,

We are using an IMX296 Monochrome sensor and we are wondering if the Jetson Orin AGX ISP supports grayscale.

In general, we are wondering if it is possible to use nvarguscamerasrc with a grayscale video sensor in the Orin AGX and dequeue grayscale colorspace (only Y elements).

Any information is highly appreciated.

Regards.

hello Carlos001,

may I double confirm what’s the pixel phase looks like.

in general,
you need below settings within ISP override file to support monochrome sensors.
for instance,

demosaic.v5.family.use=CCCC
defaults.yuvMatrix[0] = {0.3333, 0.3333, 0.3333, 0};
defaults.yuvMatrix[1] = {0, 0, 0, 0};
defaults.yuvMatrix[2] = {0, 0, 0, 0};
defaults.yuvMatrix[3] = {0, 0, 0, 1};

Hi @JerryChang ,

We set the pixel phase in the device tree as: rggb.

In general, it seems that the demasaic and defaults.yuvMatrix parameters are required to be added to the current .isp file. Is is possible to use the current pixel_phase (rggb) and add this parameters to the .isp file?

Thank you for your response

hello Carlos001,

yes, it’s also one of test approach for verification.

Hi @JerryChang ,

Thank you for the provided information, we are going to test modifying the .isp file.
