Three dimensional moving pictures with a single imager and microfluidic lens

A system for determining depth of an image comprising:

• a microfluidic lens having a variable focal length controlled by a lens controller;
• an imager receiving an image of an object from the lens, wherein the imager is configured to receive a first image comprising a first plurality of pixels from the lens at a first focal length and a second image comprising a second plurality of pixels from the lens at a second focal length, the second focal length being different than the first focal length, wherein the first image and the second image are color images;
• non-volatile memory, wherein the first image and the second image are stored in the non-volatile memory;
• and
• a depth module configured to determine a distance between the lens and the object based by a comparison of the first image of the object and the second image of the object, wherein the depth module is configured to determine the distance between the lens and the object based in part on:
• converting the first image to a first YCbCr image and the second image to a second YCbCr image;
• and
• preprocessing the first YCbCr image by applying a high-pass filter to the first YCbCr image to define a plurality of regions of the first YCbCr image, and applying a texture region identifier to each of the plurality of regions to determine whether each region is a textured region or a texture-less region.
