APPARATUS AND METHOD FOR CAPTURING STILL IMAGES AND VIDEO USING CODED LENS IMAGING TECHNIQUES
First Claim
Patent Images
1. An apparatus for coding images comprising:
- a light-sensitive sensor configured to detect visible light representing a scene;
a coded lens array including a plurality of lenses arranged in a first dimension and a second dimension and coupled together to form a two dimensional coded pattern cyclically repeated at least once in both dimensions;
wherein the coded pattern is arranged to cause an overlapping of images projected from lenses onto the light-sensitive sensor;
an analog to digital converter electrically coupled to the light sensitive sensor, the A/D converter to convert an analog signal representing visible light detected by the light-sensitive sensor to a digital signal; and
an image reconstruction processor to process the digital signal and generate a reconstructed image of the scene, the reconstruction processor including program code and/or circuitry to compensate for the different levels of attenuation by adjusting intensity at different regions of the reconstructed 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.
