An active pixel array has the signal output of each pixel connected to a first column conductor, and a reset switch connected to a second column conductor. The first and second column conductors are connected to a read-reset amplifier. The read-reset amplifier operates in a first mode in which a reset voltage is applied to the second column line, and in a second mode in which pixel output signals are buffered from the first column line. The read-reset amplifier can also operate as a comparator forming part of an ADC circuit.
