摘要：
Methods and apparatuses for row-wise dark level non-uniformity compensation of imaging sensor pixel signals. A column dependent dark reference value is determined as one of a linear and parabolic function of signal values from two areas of dark reference pixels and a column location and then used for dark level non-uniformity compensation of signal values from imaging pixels.
