1. A device for obtaining images comprising: an imaging subsystem for capturing images, the imaging subsystem comprising an image sensor; wherein the device is configured for: generating a vertical synchronization signal having alternating active high periods and active low periods; acquiring a first plurality of images based on a first control parameter; adjusting the first control parameter for a first subsequent image of the first plurality of images based on a first prior image of the first plurality of images during an active high period of the vertical synchronization signal; acquiring a second plurality of images based on a second control parameter that is different from the first control parameter; and adjusting the second control parameter for a second subsequent image of the second plurality of images based on a second prior image of the second plurality of images during an active high period of the vertical synchronization signal; and wherein the first control parameter for image N+2 is based on image N, and the second control parameter for image N+3 is based on image N+1.
