1. A method comprising: accessing image data captured by an image sensor in each of a plurality of cameras in a camera array, each image sensor comprising an image sensor window and a read window smaller than and located within the image sensor window, the image data from each image sensor representative of light incident upon the read window during capture, a first camera in the camera array including a first portion of a first field of view that overlaps with a second portion of a second field of view of a second camera in the camera array; identifying a portion of the accessed image data representative of the first portion of the first field of view and a portion of the accessed image data representative of the second portion of the second field of view; determining a set of correlation coefficients for the identified portions of image data representative of an amount of correlation within the image data portions; and responsive to the set of correlation coefficients representing a below-threshold level of correlation, adjusting the location of one or more of the read window of the image sensor of the first camera and the read window of the image sensor of the second camera.
