1. An imager array, comprising: a plurality of cameras, where each camera comprises a two dimensional arrangement of pixels having at least two pixels in each dimension and each camera is contained within a region of the imager array that does not contain pixels from another camera; control circuitry configured to capture image data using the plurality of cameras, wherein the control circuitry is configured to control the capture of the image data by the pixels within the cameras, where the control circuitry is configured so that the capture of image data by the pixels in at least two of the cameras is separately controllable; master control logic circuitry configured to control the read-out of pixel data from the plurality of cameras by: generating at least one line of image data by multiplexing said image data captured by said plurality of cameras; generating additional data, where said additional data comprises information regarding operating parameters of said plurality of cameras and information for demultiplexing the captured plurality of images from the generated at least one line of image data; packetizing said at least one line of image data and said additional data to produce at least one packet of data; and output interface circuitry configured to transmit said at least one packet of data via an output interface.
