We have some doubts about the WDR support on the Jetson boards. As far as we know the Jetson ISP supports the WDR combination on-sensor, it means that the long/short exposures are combined at the sensor side, and the 24-bit or 20-bit result is compressed with a PWL algorithm to 12-bits and sent over CSI-2. When the Jetson captures the frames, the ISP processes them applying the PWL decompression and finally applying a tone mapping algorithm, to achieve one single frame at the output of the ISP.
Is my understanding correct?
Is this the only HDR mode supported?
Does the Jetson Nano supports this functionality?
Thanks for your help in advance.
