Patent ID: 8248515

Claim:
A digital imaging system comprising: an optics arrangement, including a main lens, and a microlens array at a two dimensional focal plane of the main lens; a photosensor array comprising a plurality of photosensors, wherein the optic arrangement directs light rays from a scene to be sensed by the photosensor array, and wherein the photosensor array outputs light data characterizing the sensed light rays; and a control arrangement configurable to set a distance between the photosensor array and the microlens array, wherein at a first position the distance is approximately zero, and a spatial resolution of an image of the scene captured by the digital imaging system approaches a maximum achievable value, and wherein at a second position the distance is approximately one focal length of the microlens array, and the image of the scene captured by the imaging arrangement approaches a maximum achievable directional resolution such that a focal point of the captured image may be changed after the image of the scene is captured.
