1. An apparatus for coding grayscale or color images comprising:
- a coded lens array including a plurality of lenses coupled together to form a two-dimensional coded pattern repeated at least twice in a horizontal dimension and at least twice in a vertical dimension, forming a 2×
2 mosaic,a light-sensitive sensor to capture overlapping patterns of visible light projected through the coded pattern which is reconstructed into a grayscale or color image.

Abstract
An apparatus for capturing images. In one embodiment, the apparatus comprises: a coded lens array including a plurality of lenses arranged in a coded pattern and with opaque material blocking array elements that do not contain lenses; and a light-sensitive semiconductor sensor coupled to the coded lens array and positioned at a specified distance behind the coded lens array, the light-sensitive sensor configured to sense light transmitted through the lenses in the coded lens array.

11. An apparatus for coding grayscale or color images comprising:
-
a coded lens array in a two-dimensional 2×
2 mosaic of a coded pattern repeated at least twice in a horizontal dimension and at least twice in a vertical dimension that diffracts light transmitted through the coded lens array onto a light-sensitive sensor which is reconstructed into a grayscale or color image;wherein the pattern incident upon the light-sensitive sensor is an overlapping of the image of a subject positioned in front of the coded lens array as projected through a plurality of Uniformly Redundant Array (URA) patterns. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
