1. An apparatus for enhancing large-format digital images, the apparatus comprising: one or more primary optical systems; and one or more secondary optical systems, each secondary optical system including one or more electro-optical detector arrays and at least two prisms, the at least two prisms being configured to collect light energy from disparate locations and project the respective collected light energy onto a common one of the one or more electro-optical detector arrays, wherein each of the one or more primary optical systems is configured to produce primary image content, and wherein each of the one or more secondary optical systems is configured to produce secondary image content, the secondary image content being arranged with respect to the primary image content such that an angle-of-view of the primary image content is extended by the secondary image content, and wherein the apparatus comprises a first secondary optical system configured to collect light energy for enhancing the primary image content in the left and right directions and a second secondary optical system configured to collect light energy for enhancing the primary image content in the fore and aft directions.
