Patent Images

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.
