A pipelined readout method in an image sensor includes receiving one or more signals from a pixel of a row of a pixel array into a column storage at least partially during a time that a previously sampled amplified output of the column storage that is based on signals provided by a previous pixel of a previously read out row of the pixel array is converted from analog to digital by an analog-to-digital conversion circuit. The method further includes performing, by the analog-to-digital conversion circuit, analog-to-digital conversion of a sampled amplified output of the column storage that is based on the one or more signals from the pixel at least partially during a time that the column storage receives at least one signal from a another pixel of a subsequently read out row of the pixel array.
