CMOS imager for cellular applications and methods of using such
First Claim
Patent Images
1. A CMOS imager, wherein the CMOS imager comprises:
- an image sensor;
a sub-sample control system, wherein the sub-sample control system is operable to identify one or more signals from the image sensor that are not processed;
an analog processing circuit, wherein the analog processing circuit receives the one or more signals from the image sensor at one or more inputs; and
a processing control system, wherein the processing control system is operable to limit switching of the one or more inputs.
