I've always been dubious of manufacturers'
claims of multi-megapixel cameras on phones and
cams that cost only a couple hundred dollars, when
condisering that high-end cameras of less pixel
numers cost x10 as much. This brief article in the
May 2012 edition of IEEE's
magazine does a nice job of summarizing the differences.
