First Claim
1. An optical-electronic array for use at least as a sensor in a system for numerical image formation and for refinement from overlapping measurement vignettes of an incoming light field associated with an observed scene, the optical-electronic array comprising:
- An array of optical-electronic elements, each associated with a vignetting micro-optical arrangement, each optical-electronic element producing a light detection signals;
A multiplexing arrangement for gathering the light detection signals from each optical-electronic element and for producing a stream of measurement values responsive to an incoming light field presented to the sensor and associated with an observed scene;
Wherein the optical-electronic array creates a plurality of light detection signals responsive to a plurality optically vignetted portions of an incoming light field associated with an observed scene.

Abstract
A vignetted optoelectronic array for systems and methods performing electronic image formation and refinement from overlapping measurement vignettes captured by an array of image sensors and associated micro-optics. The invention is directed to a new type of image formation system that combines readily-fabricated micro-optical structures, a two-dimensional image sensor array, and electronic or digital image processing to construct an image. Image formation is performed without a conventional large shared lens and associated separation distance between lens and image sensor, resulting in a “lensless camera.”
In an embodiment, an LED array is used as alight-field sensor. In an application, the LED array further serves as a color “lensless camera.” In an application, the LED array also serves as an image display. In an application, the LED array further serves as a color mage display. In an embodiment, one or more synergistic features of an integrated camera/display surface are realized.
