1. An apparatus for acquiring image data sets of a given scene via two or more optical paths, said apparatus comprising: a single image sensor array including an array of light sensing elements; and at least first and second optical paths configured to interleavingly direct light from the given scene, received via different optical paths, onto said single image sensor array concurrently, such that image information from said first optical path and said second optical path is concurrently directed onto interleaving light sensing elements of said array of light sensing elements of said single image sensor array, such that: (1) each given light sensing element of at least a majority of said light sensing elements sensing image information received via said first optical path is situated such that one or more of said light sensing elements sensing image information received via said second optical path are situated to each of four sides of the given light sensing element; and (2) each individual light sensing element of at least a majority of said light sensing elements sensing image information received via said second optical path is situated such that one or more of said light sensing elements sensing image information received via said first optical path are situated to each of four sides of the individual light sensing element.
