1. An imaging apparatus comprising: an image sensor array for generating frames of image data, the image sensory array comprising shared global shutter circuitry; wherein the imaging apparatus, when in a first configuration, is configured for: sequentially initiating exposure of pixels of a first row and a second row of pixels of the image sensor array; and reading out a frame of image data from the image sensor array wherein pixel values are un-binned pixel values that represent light incident on a spatial area delimited by a single pixel of the image sensor array; wherein the imaging apparatus, when in a second configuration, is configured for: simultaneously initiating exposure of pixels of a first row and a second row of pixels of the image sensor array; simultaneously terminating exposure of pixels of the first row and the second row of pixels of the image sensor array; and reading out a frame of image data from the image sensor array using the shared global shutter circuitry, wherein pixel values are binned pixel values that represent light incident on a spatial area delimited by an arrangement of two or more pixels of the image sensor array.
