1. A system for endoscopic visualization in a light deficient environment, the system comprising:
an image sensor comprising a pixel array that reads out a plurality of data frames over a plurality of frame periods, wherein each of the plurality of frame periods comprises a blanking period and a readout period; and
a controller that synchronizes operations of the image sensor with a variable pulse cycle of an emitter;
wherein the controller calculates register values for an applied gain for the image sensor on a per-frame basis;
wherein the calculation of the register values for the applied gain is based at least in part on a type of a data frame of the plurality of data frames; and
wherein the controller calculates a duration of each of the plurality of frame periods on a per-frame basis.
