1. An apparatus for exposure control, the apparatus comprising:
at least one memory; and
at least one processor coupled to the at least one memory and configured to:
determine a first exposure relationship between an exposure of a first image frame from a first camera of a multi-camera system and an exposure of a second image frame from a second camera of the multi-camera system, wherein the multi-camera system comprises a plurality of cameras comprising the first camera and the second camera;
determine a second exposure relationship between an exposure of a third image frame from the first camera and an exposure of a fourth image frame from the second camera;
determine a difference between the second exposure relationship and the first exposure relationship; and
apply, based on a comparison of the difference to a threshold value, first exposure statistics of the first camera to the plurality of cameras.
