Systems and methods are provided that facilitate mitigating pixel or column fixed pattern noise in a CMOS imaging System-on-Chip (iSoC) sensor. For instance, pixel or column fixed pattern noise can be recognized by gating a pixel array without firing a transfer signal (TX). Inhibiting the transfer signal can cause zero input to be provided to pixels in the pixel array; thus, the sampled output from the pixels under such conditions can be a function of noise. Calibration and correction can thereafter be effectuated. Moreover, uniform frame rates for outputted frames can be yielded irrespective of use of a subset of read out frames for calibration. For example, frames employed for calibration can be replaced in a sequence of outputted frames by copies of stored frames. Further, signal levels can be balanced to account for differences in light integration time, which can result from blocking and unblocking firing of transfer signals.
