Method for deblurring images using optimized temporal coding patterns
First Claim
Patent Images
1. A method for reducing blur in an image of a scene acquired by a camera, comprising the steps of:
- selecting an optimal temporally coded pattern;
temporally modulating light of a scene acquired and integrated by a camera image sensor according to the temporally coded pattern during an exposure time to generate an encoded input image; and
decoding the encoded input image according to an inverse of the coded pattern to produce a decoded output image having a reduced blur.

Abstract
A method and system deblurs images acquired of a scene by a camera. A light field acquired of a scene is modulated temporally according to a sequence of ons and offs. An optimal coding pattern is selected. The modulated light field is integrated by a sensor of a camera during an exposure time to generate an encoded input image. The encoded input image is decoded according to a pseudo-inverse of a smearing matrix to produce a decoded output image having a reduced blur.
