1. A camera array, comprising:

  • A plurality of cameras, where each camera includes a separate optics, and a plurality of light sensing elements, and each camera is configured to independently capture an image of a scene;

    wherein the optics of each camera are configured so that each camera has a field of view that is shifted with respect to the field-of-views of the other cameras so that each shift includes a sub-pixel shifted view of the scene;

    wherein the light sensing elements have a pixel pitch defining the Nyquist frequency, and where the optics of each camera have a modular transfer function (MTF) such that the optics optically resolve, with sufficient contrast, spatial frequencies larger than the Nyquist frequency (Ny);

    wherein the camera array is a monolithic integrated module comprising a single semiconductor substrate on which all of the sensor elements are formed, and optics including a plurality of lens elements, where each lens element forms part of the separate optics for one of the cameras;

    wherein each of the cameras includes one of a plurality of different types of filer; and

    wherein cameras having the same type of filter are uniformly distributed about the geometric center of the camera array.
