After loading the driver of imx728, previewing the sensor with argus_camera found that when the lens moved quickly, a partial shadow appeared at the light source. As shown in the following figure, while checking the log, it is found that the gain of the sensor has been set to the maximum, instead of keeping the default value. Can you help me solve these two problems?
hello fyx15515327378,
is it running with SDR mode, or WDR mode?
also, can this issue recover when you target at another new scene?
hello JerryChang，
I used the hcg mode, and the above situation only occurs when shooting the light source and moving the lens.
did you meant… High Conversion Gain.? this also not in SDR mode, or, linear mode.
please check with sensor vendor to ensure this is pass the sanity test.
hello JerryChang，
The linear mode of imx728 was used, and then we chose the High Conversion Gain mode as the signal line.
There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
let’s narrow down the issue,
how about disable HCG, or using dummy gain value to check you’re still seeing the same?
