I have configured AE LIMITS with the maximum exposure set accordingly. However, during runtime, the AE algorithm only reaches 66666 exposure at most,and the gain hits its upper limit at this point. Readings via V4L2 confirm that AE exposure reaches less than half of the configured upper limit.
When manually configuring exposure via Live Control, the valid exposure can reach 150000,V4L2 exposure can also reach the upper limit.
We suspect this issue is related to RowTime. We modified the Row Time parameter inside AE Dister, but this change shows no visible effect; the auto exposure performance remains exactly the same as before.
We would like to know what adjustments are required to allow the AE algorithm to reach the configured maximum exposure under low-light conditions.
