Using a plurality of motion corrected images to improve pixel value estimation in a final combined image

摘要

An image having higher resolution and/or better color is generated from multiple images (210, 220, 230) of a subject taken by a handheld imaging device. The motion of the device, even when a user holds the device steady, gives the images perspectives that differ by an amount ranging from a fraction of a pixel to a few pixels, and the differences are used to create a better image. An image shifted by a non-integer number of pixels relative to another image provides information about portions of the subject that are between the pixels of the other image and usable for increasing resolution. Images shifted relative to each other by an integral number of pixels have aligned pixels that may provide different color information for the same portion of the subject when the aligned pixels correspond sensor elements having different color filters.
