1. An apparatus for regionally controlling exposure time, comprising: a sensor array comprising a plurality of sensors and configured to generate a plurality of images, wherein each of the plurality of images is generated under different exposure conditions; and a processor coupled to the sensor array and configured to: determine one or more weight values for each image in the plurality of images; combine the plurality of images into a single image based on a comparison of the one or more weight values for each image; identify an object in the single image, wherein the object comprises a light emitting diode (LED) having an ON duration and an OFF duration; determine a region of sensors of the plurality of sensors corresponding to the identified object; generate a clock cycle that operates in sync with the ON duration and the OFF duration of the LED; and determine an exposure condition of one or more sensors within the region of sensors based, at least in part, on the ON duration of the LED.
