"Mitsuba has chosen to label this camera as being 12MP on several places
on the box. While the true optical resolution of the DC500T is only 5MP,
the 12MP figure is obtained through interpolation. Since the Mitsuba
does this interpolation in the camera I suppose the 12MP figure is
technically correct, but its use here is obviously meant to mislead the
user into thinking they are getting a much higher end camera."
