Structural parameters of spheroids and disks are presented for a homogeneous sample of 167 galaxies of all morphological types, and systematic properties and interplay of the spheroid and disk are explored using a new technique to derive the structural parameters from the observed luminosity distribution. The luminosity distributions of most of the galaxies, including all of the elliptics, can be well approximated by two-component models, with the rest approximated by one-component disk models. Spheroids of disk galaxies are on average less luminous in absolute magnitude and have both fainter brightness-scale parameter and larger length-scale parameter than those of elliptics. Spheroid parameters of S0 galaxies are intermediate between those of elliptics and spirals.
