6. A method for addressing X-Y paxels in an imaging system, comprising the steps of:
-
a) capturing a first image;
b) testing the first image for saturation on a paxel by paxel basis, wherein the paxels are groups of pixels associated geographically with each other;
c) recording an X-Y address for each saturated paxel within the first image;
d) determining the number of saturated paxels;
e) comparing the number of saturated paxels to a constant, N, where the number of saturated paxels is greater than zero;
f) varying integration time of the saturated paxels according to the number of saturated paxels being greater than or less than the constant N;
-
- 7. An electronic image capture system comprising an imager that enables independent integration time control of paxels and an algorithm for determining the correct integration time for the paxels based on their saturation level.
