Abstract
It is proposed that the number 
, given by 
![[\\int_{0}^{\\infty}T(f) df]^{2}](/images/tex/15632.gif)
, is equal to the number of picture elements in an image within which the noise-free modulation transfer function 
of the image device (display) is uniform and isotropic; 
and 
are the edge lengths (mm) of a rectangular format, and 
is the spatial frequency (cycles/mm). An equation for , that applies to nonuniform and anisotropic modulation transfer functions is also given. A picture element transfer efficiency 
is defined as ( 
), where 
is the number of picture elements transferred to the image (display) by an "ideal" device.
