Abstract: An imaging camera device comprising (1) an image sensor, (2) a spherical-power adapter coupled to the image sensor, wherein the spherical-power adapter moves the image sensor relative to an imaging lens, (3) a field-curvature adapter coupled to at least one optical component placed between the image sensor and the imaging lens, wherein the field-curvature adapter adjusts the size of a variable air gap formed between the optical component and at least one additional optical component, and (4) a cylindrical-power adapter that includes a plurality of cylindrical correction lenses applied to a wheel configured to rotate in at least one direction. Various other apparatuses, systems, and methods are also disclosed.

Abstract: An apparatus comprising (1) a conoscope configured to receive an image emitted by a display device through a corrective lens, (2) a variable compensation element coupled to the conoscope, wherein the variable compensation element is capable of selectively modifying the image emitted by the display device to compensate for an optical effect imparted by the corrective lens on the image, and (3) a controller coupled to the variable compensation element, wherein the controller (1) receives a compensation parameter representative of the optical effect imparted by the corrective lens on the image, (2) selects, based at least in part on the compensation parameter, a feature of the variable compensation element that compensates for the optical effect, and (3) causing the feature of the variable compensation element to be applied to the image. Various other apparatuses, systems, and methods are also disclosed.
