Inquiry About Resolution Correction and Display Handling on NVIDIA Orin

[lloyd.kim]

Hello, we are in the process of setting up a new camera using the Nvidia Orin. During the setup, we noticed that the camera’s resolution output is irregular (not 1920x1080 but varying between 1912~1920 x 1072 ~ 1080). Despite this, Nvidia is correctly outputting the resolution as 1920x1080 to an HDMI display. The parts of the display where no video input is received are shown in green, which we can confirm. We suspect that the areas marked with a red box in the attached file indicate where the video input is not being properly received and is being corrected.

Other chips (QXXXXXX or TXXXXX) do not support this feature, and the camera display is either unrecognizable or causes problems in CSI, making it impossible to verify the camera image.

My questions are as follows:

1. Is this correction feature supported by hardware?
2. What is this technology called?

I need accurate information for the report I am preparing.

I don’t think there’s any correction feature.
USB/CSI camera?

[lloyd.kim]

Yes, it’s a CSI camera.

Looks like dummy pixel at the end of line and frame.

[lloyd.kim]

I am curious if the Nvidia Orin handles the addition of dummy pixels through hardware, and if so, which hardware component is responsible for this?

[ShaneCCC]

Orin software/HW doesn’t handle any dummy pixels.

Thanks

For my final question, is there a possibility that the graphics driver is set up to leave spaces empty for any parts not inputted, according to the output resolution information?

[ShaneCCC]

The display show green if the pixel data is zero.
