Abstract

A camera comprising various arrangements for employing optical elements in association with photosensitive elements are described. In some of the arrangements, the optical elements are formed integrally with a substrate containing the photosensitive elements. In other arrangements, an optical element is mounted to a package, or the like, containing the substrate and photosensitive elements. In other arrangements, two or more optical elements are employed, including conventional refractive elements, refractive focusing elements, and refractive beam splitting elements. Utility as solid state image sensors is discussed. Utility for monochromatic and color imaging is discussed. Various devices based on such camera arrangements and methods of making same are discussed.

Claims

1. An image-sensing display panel, comprising:

an LCD display panel;

a substrate having;

a photosensor array disposed on a surface of the substrate; and

an optically transmissive layer above and contiguous with the array, wherein said transmissive layer is capable of focussing light onto said array;

wherein said LCD display panel, and said substrate are aligned along the same optical path; and

the photosensor array comprises;

a plurality of lenses for forming a substantially identical light image on laterally spaced areas of a surface respectively; and

a plurality of photosensors disposed on said surface within said laterally spaced areas for receiving different portions of said light image respectively such that the photosensors in aggregation receive substantially all of said light image.
