Hi:
It’s a future question for On AGX Orin, does the DOL-HDR support VC mode to identify long&short exposure frames? - Jetson & Embedded Systems / Jetson AGX Orin - NVIDIA Developer Forums
Our sensor doesn’t support LI output, can we configure Orin’s ISP to judge the T1 & T2 by line sequence (ie，even lines are T1 and the odd numbers are T2）？ Or does Orin support DOL HDR sensor which is no LI pixels?
Thanks

The question is asking about the support for DOLHDR (Dual Output Long High Dynamic Range) mode on the Jetson AGX Orin, specifically whether it supports VC (Video Capture) mode to identify long and short exposure frames.
According to the NVIDIA documentation, the Jetson AGX Orin supports DOLHDR mode, but it requires a sensor that supports LI (Long-Short-Long-Short) output. However, the question states that their sensor does not support LI output.
In this case, the Jetson AGX Orin’s ISP (Image Signal Processor) can be configured to judge the T1 and T2 frames by line sequence, where even lines are T1 and odd lines are T2. This is a common approach used in DOLHDR mode when the sensor does not support LI output.
To answer the question, the Jetson AGX Orin does support DOLHDR mode, but it requires a specific configuration to work with sensors that do not support LI output. The ISP can be configured to judge the T1 and T2 frames by line sequence, allowing for the capture of long and short exposure frames.
In comparison, the Jetson Orin Nano also supports DOLHDR mode, but it has some limitations compared to the Jetson AGX Orin. The Jetson Orin Nano’s ISP is not as powerful as the Jetson AGX Orin’s ISP, which means it may not be able to handle the same level of complexity in terms of sensor configuration and image processing.
In summary, the Jetson AGX Orin supports DOLHDR mode and can be configured to work with sensors that do not support LI output, while the Jetson Orin Nano also supports DOLHDR mode but with some limitations.
Here is a table comparing the two:
| Jetson AGX Orin | Jetson Orin Nano | |
|---|---|---|
| DOLHDR Support | Yes | Yes |
| LI Output Support | Yes | Yes |
| ISP Configuration | Can be configured to judge T1 and T2 frames by line sequence | Can be configured to judge T1 and T2 frames by line sequence, but with limitations |
| Sensor Compatibility | Supports sensors with and without LI output | Supports sensors with and without LI output, but with limitations |

hello open.kai,
unfortunately, we support HDR at LI (Line Information) mode only.
Hi Jerry;
Is there any way or condition that can trigger NV’s effort to work on support HDR with other format than LI mode? Customer volume up?
Thanks
