First Claim
Patent Images
1. A method for capturing video, comprising:
- capturing a first image with a continuous shutter;
capturing a second image with a flutter shutter;
capturing a third image with the continuous shutter;
determining the motion of an object relative to the continuous and flutter shutters from the first and third images;
estimating blur from the motion of the object and the second image;
developing one or more de-blur parameters from the estimated blur; and
applying the one or more de-blur parameters to the second image.

Abstract
A heterogeneous video capturing system having motion and blur estimation. An item of motion may be captured with a continuous shutter and a flutter shutter. The flutter shutter image may be preceded and following by a continuous shutter image. Motion of a subject of the images may be estimated from the shutter images. The estimated motion may be a basis for blur estimation and blur removal from the flutter shutter image.

5. A flutter shutter image capturing system comprising:
-
a flutter shutter; a continuous shutter; and a processor controlling the flutter shutter and the continuous shutter; and wherein; an image captured by the flutter shutter is preceded by an image captured by the continuous shutter and followed by an image captured by the continuous shutter; parameters of motion of an object in the images relative to the continuous and flutter shutters are approximated from the images preceding and following the image captured by the flutter shutter; and the parameters of motion are input to the processor for obtaining a blur estimate of the image captured by the flutter shutter. - View Dependent Claims (6, 7, 8, 9, 10)

11. A video capture system comprising:
-
a camera; a processor connected to the camera; and wherein the camera comprises; a continuous shutter; and a flutter shutter; and wherein; a first image of a target is captured with the continuous shutter; a second image is captured with the flutter shutter; a third image is captured with the continuous shutter; the images taken with the continuous shutter before and after each image with the flutter shutter are analyzed to provide an approximation of motion of the target to obtain a blur estimation of the image taken with the flutter shutter; and the blur estimation is used for de-burring the image taken with the flutter shutter. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
