Method for correcting an acquired image
First Claim
Patent Images
1. A method of correcting an image obtained by an image acquisition device comprising:
- obtaining a first measurement of device movement during exposure of a first row of an image and a second measurement of device movement during exposure of a second row of the image, Gn;
selecting an integration range, idx, based, at least in part, on an exposure time, te, for the first row of the image and the second row of the image,averaging accumulated measurements, Cn, of device movement for the first row of the image and the second row of the image to provide a filtered measurement,G, of device movement during exposure of the first row of the image and the second row of the image, andcorrecting the image for device movement using the filtered measurement G.

Abstract
A method of correcting an image obtained by an image acquisition device includes obtaining successive measurements, Gn, of device movement during exposure of each row of an image. An integration range, idx, is selected in proportion to an exposure time, te, for each row of the image. Accumulated measurements, Cn, of device movement for each row of an image are averaged across the integration range to provide successive filtered measurements,

11. A system comprising:
-
a processor; and memory in communication with the processor; an image processing pipeline configured to provide an image for correction, and in communication with the processor; instructions, stored in the memory, which when executed by the processor configure the system to perform actions comprising; obtaining a first measurement of device movement during exposure of a first row of an image and a second measurement of device movement during exposure of a second row of the image, Gn; selecting an integration range, idx, based, at least in part, on an exposure time, te, for the first row of the image and the second row of the image, averaging accumulated measurements, Cn, of device movement for the first row of the image and the second row of the image to provide a filtered measurement, G , of device movement during exposure of the first row of the image and the second row of the image, andcorrecting the image for device movement using the filtered measurement G . - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
