First Claim
Patent Images
1. An image acquisition system comprising:
- an image sensor comprising a plurality of pixels; and
a plurality of cylindrical microlenses formed on a surface, the surface being on or above the image sensor,wherein each cylindrical microlens is configured to focus radiation on a subset of the plurality of pixels, andwherein each cylindrical microlens has a first portion configured to focus radiation on a first portion of its subset of pixels, and a second portion configured to focus radiation on a second portion of its subset of pixels.

Abstract
The invention discloses an image acquisition system with a modified image sensor that enables simultaneous capture of at least two images with different perspectives The pixels are split into two or more subsets of pixels under a series of cylindrical microlenses or linear light guides. The cylindrical microlenses or linear light guides limit the radiation to impinge upon first and second subsets of pixels under each microlens or light guide to come from only one half or the other half of the imaging lens so that stereo image sets are produced.
