Abstract: An integrated circuit active pixel image sensor comprises an array of active pixels having associated therewith one capacitor in each pixel column for storing a combined pixel output signal comprising an image signal and a fixed offset signal and another capacitor in each column for capturing another signal produced when the pixel is reset. The array may be read row-by-row. Each column includes a comparator and a data latch via which a digitized fixed offset corrected pixel output signal is obtained using a ramp voltage source and a digital count broadcaster provided in the sensor.
