AM62A7: The problem of adjusting the sequence of AE and GLBCE

AM62A7: GLBCE mode inquiry

Hi TI experts

By consulting the AM62A technical manual, we found that GLBCE has two modes.

The first mode we are currently using is   “GLBCE Continuous Frame Processing”.


May I ask which settings can be used to switch to the second mode?

    Hi Peng,

    The 2nd mode is not suitable for continuous video.
    Every sensor frame will have to be processed twice and that reduces the effective VISS fps to 50%.
    e.g., if VISS can process 300MP/s in mode-1, then it can only support ~150MP/s in mode-2.

    Hi Gang 

    May I ask how to switch to the second mode? We would like to try to see if we can solve the issue of flickering.

    There is no a special H/W mode for that.
    It is simply passing every image through VISS twice so that GLBCE context is update in the first pass.
