Patent ID: 8717489

Claim:
A digital imaging system comprising: a main lens; a microlens array at a two-dimensional focal plane of the main lens; a photosensor array comprising a plurality of photosensors, wherein light rays from a scene to be imaged pass through the mains lens and the microlens array and are sensed by the photosensor array, and 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 at a second position the distance is greater than or equal to 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.
