PIXEL ASPECT RATIO CORRECTION USING PANCHROMATIC PIXELS

摘要

Method for forming an enhanced digital full-color image having a first pixel aspect ratio includes capturing an image using an image sensor having panchromatic pixels and color pixels corresponding to at least two color photoresponses wherein color and panchromatic pixels each have a second pixel aspect ratio different from the first pixel aspect ratio, providing from the captured image a digital high-resolution panchromatic image and changing the aspect ratio of the panchromatic pixel values from the second pixel aspect ratio to the first pixel aspect ratio to produce a digital aspect corrected high-resolution panchromatic image, providing from the captured image a digital low-resolution color difference color filter array image, providing a digital aspect corrected high-resolution color difference image from the low-resolution color difference color filter array image, and using the aspect corrected high-resolution panchromatic image and an aspect corrected high-resolution color difference image to produce the enhanced digital full-color image.
