1. A camera, comprising:

  • a photosensor configured to capture images projected onto the photosensor;

    an objective lens array comprising N discrete objective lenses, wherein N is an integer greater than or equal to two, wherein each objective lens is configured to refract light from a subject located in front of an aperture of the camera; and

    a lenslet array located between the objective lens array and the photosensor, wherein the lenslet array comprises M lenslets, where M is an integer greater than or equal to two, wherein each lenslet in the lenslet array is configured to;

    refract light from each of the N objective lenses in the objective lens array; and

    separate the light refracted from the N objective lenses and project the separated light onto N separate subregions of a region of the photosensor corresponding to the lenslet to thus project N separate images of the subject onto the region of the photosensor.
