Abstract
Aspects relate to improved optically black reference pixels in a CMOS iSoc sensor. A system can include a pointer Pthat indicates pixels to be read out during a readout time interval, a pointer Pthat indicates pixels to be reset during the time interval, and a pointer Pthat preserves a validity of a frame. The system also includes a pointer Pconfigured to mitigate an integration time of column fixed pattern noise (FPN) rows independently of the integration time of other rows. In some aspects, pointer Pcan mitigate blooming into sampled rows from surrounding rows. Pointer Pcan be continuously rotated, in an aspect. Further, in some aspects, pointer Pcan jump on a second cycle to arrive one line before pointer P
