Method for forming an improved image using images with different resolutions
First Claim
1. A method implemented at least in part by a data processing system, the method for forming an image with reduced motion blur and increased signal to noise ratio, and the method comprising the steps of:
- acquiring one or more high resolution images and two or more lower resolution images of a scene over a contemporaneous period of time, wherein the acquired high resolution images are acquired using an image acquisition mode that results in images that have motion blur less than the lower resolution images and wherein the lower resolution images are acquired using a different image acquisition mode that results in images that have lower resolution and higher signal to noise ratio than the high resolution images;
forming a corrected set of images at least by using common features in the low and high resolution images to align some of the lower resolution images to correct for motion present between the lower resolution images and the higher resolution image;
forming a synthesized high resolution image with reduced motion blur and higher signal to noise ratio at least by merging (a) a portion of one of the images in the corrected set of images, and (b) a portion of a high resolution image; and
storing of the synthesized image in a processor-accessible memory system.

Abstract
Multiple images of a scene are acquired over a contemporaneous period of time. Most of the multiple images are lower resolution images acquired with a lower resolution than the other of the multiple images. A corrected set of images is formed at least by correcting for motion present between at least some of the lower resolution images. In addition, a synthesized image is formed at least by merging (a) at least a portion of at least one of the images in the corrected set of images, and (b) at least a portion of at least one of the other of the multiple images. The synthesized image is stored in a processor-accessible memory system. The synthesized image exhibits improved image quality including reduced motion blur, a higher signal-to-noise ratio, and higher resolution over conventional techniques.

-
acquiring one or more high resolution images and two or more lower resolution images of a scene over a contemporaneous period of time, wherein the high resolution images are acquired using an image acquisition mode that results in images that have motion blur less than the lower resolution images and wherein the lower resolution images are acquired using a different image acquisition mode that uses binning to result in images that have lower resolution and higher signal to noise ratio than the high resolution images; forming a corrected set of images at least by using common features in the low and high resolution images to align some of the lower resolution images to correct for motion present between the lower resolution images and the higher resolution image; forming a synthesized high resolution image with reduced motion blur and higher signal to noise ratio at least by merging (a) a portion of one of the images in the corrected set of images, and (b) a portion of a high resolution image; and storing of the synthesized image in a processor-accessible memory system. - View Dependent Claims (17, 18, 19, 20, 21)
