1. A process for generating a combined image, comprising:
taking a plurality of images of a subject using a handheld device;
analyzing the images to determine relative motion of the images; and
for each pixel in the combined image,
identifying one or more nearby pixel that after correcting for the determined relative motion of the images are less than a threshold distance from a location corresponding to the pixel in the combined image; and
determining a pixel value for the pixel in the combined images from one or more pixel values of the nearby pixels.
