ABSTRACT:
In a size determining system, a number of pixels in a dimension of a sensor array of photoelectric devices is determined. A readout register is arranged to receive charge accumulated in the dimension of the sensor array. A clock is connected to apply clock cycle pulses to the readout register to read out the charge from the readout register for a predetermined number of clock cycles known to exceed a supposed maximum number of pixels in the dimension of the sensor array. A discontinuity detector is operative to determine a first discontinuity in the readout charge, representing a last active pixel in the dimension of the sensor array. A counter is arranged to count clock cycles between a first active pixel and the first discontinuity to determine a number of active pixels in the dimension of the sensor array.
