Abstract
Systems and methods are provided that facilitate employing a plurality of independent reset buses for a column of pixels in a pixel array of a CMOS sensor imager. Utilization of the plurality of independent reset buses for the column of pixels can enable independent reset to be effectuated when employing sub-frame integration. For example, rows to be read and reset during a given readout time interval can be selected based upon one or more criteria. Further, each of the rows selected during the given readout time interval can be associated with a respective distinct reset bus. By leveraging the plurality of independent reset buses, uniformity in pixel operation can be maintained whether operating in full frame integration mode or sub-frame integration mode. Thus, noise resultant from changing between integration modes can be mitigated by using the plurality of independent reset buses.
