<p>An image sensor includes a two-dimensional array of pixels having multiple column outputs and an output circuit connected to each column output. Each output circuit is configured to operate concurrent sample and read operations. An analog front end (AFE) circuit processes pixel data output from the output circuits and an AFE clock controller transmits an AFE clocking signal to the AFE circuit to effect processing of the pixel data. A timing generator outputs a column address sequence that is received by a column decoder. During one or more sample operations the AFE clock controller suspends the output of the AFE clocking signal and the timing generator suspends the output of the column address sequence during the sample operation. The output of the AFE clocking signal and the column address sequence resume at the end of the sample operation.</p>
