to measure the results of the imaging process on a
known color/gray scale target and real life subjects.
This quantitative measurement is called
sensitometry, where we measure the values of the
input and output. We can then define a function for
the changes that are introduced by the imaging
system. This transfer function can then be used to
"calibrate" the imaging system.
charge-coupled device. This is a solid state memory
unit with storage cells that can accumulate electron
charges.
the voltage gain in the scanner's CCD circuit .
the voltage limit of the CCD output can be clamped
at a particular point, allowing the black level of the
image to be established, so that regardless of the
exposure increase, the black level stays the same.
central processing unit.
trimming an image.
the process of balancing the color of an image.
Scanner plugins allow the user to control color
balance in an R,G,B color model.
there are many ways to describe color. Color spaces
are three dimensional, that is they consist of units of
measurement along three different axis. We
generally talk about three common characteristics.
