Claim of US Patent No. 10,462,399

1. An imager, comprising:a pixel array including a plurality of imaging pixels, a first non-imaging pixel configured to produce a first nominal reset signal, and a second non-imaging pixel configured to produce a second nominal reset signal having a different signal level than the first nominal reset signal;
control circuitry operably coupled to the pixel array and configured to—
output image signals based on reset signals produced by corresponding ones of the imaging pixels,
adjust a signal level of a reset signal of one of the imaging pixels proximate the first-non-imaging pixel based at least in part on the first nominal reset signal, and
adjust a signal level of a reset signal of another one of the imaging pixels proximate the second-non-imaging pixel based at least in part on the second nominal reset signal.
