ABSTRACT:
The driving system of an image sensor produces a phase controlled transfer pulses and comprises a horizontal scanning signal generator, a reference pulse producer producing a reference pulse from a horizontal scanning signal, the reference pulse being transferred through the horizontal charge transfer section of the image sensor, a comparator comparing the transferred reference pulse with the horizontal scanning signal, and a voltage controlled oscillator producing transfer pulses in accordance with the result of the comparison. The application of the transfer pulses to the horizontal charge transfer section is controlled by using a keying controlled oscillator as the volage controlled oscillator or using a gate connected after the voltage controlled oscillator.
