Application No. 10/109,390
Appellants’ invention relates to a method and apparatus for KTC noise canceling
in a linear CMOS image sensor. An understanding of the invention can be derived from
a reading of exemplary claim 1, which is reproduced below.
1. A method of reading out a pixel signal from a pixel comprising:
capturing a first black reference signal from said pixel prior to said
pixel starting an integration period;
after completion of said integration period, capturing a pixel signal;
capturing a second black reference signal following completion of
said integration period; and
outputting said first black reference signal, said second black
reference signal, and said pixel signal and using both said
first black reference signal and said second black reference
signal to modify said pixel signal.
