1. A method comprising: capturing a first digital image and a second digital image in quick succession, thereby recording similar image information, and comparing the image data of the first digital image to the image data of the second digital image to identify a plurality of regions of significant difference between the first digital image and the second digital image; and for each of the plurality of identified regions: determining if the second digital image contains a preferred rendition of that identified region; if the second digital image contains the preferred rendition, blending that identified region from the second digital image into that identified region of the first digital image; and if the second digital image does not contain the preferred rendition, retaining that identified region in the first digital image, wherein comparing comprises: subtracting the image data of one of the first and second digital images from the image data of the other of the first and second digital images to create a third digital image representing the difference between the first and second digital images; and applying an algorithm to the third digital image to identify the plurality of regions of significant difference, wherein the identified plurality of regions conform to characteristics associated with differences between open eyes and eyes that are closed or partially closed.
