In an example, the image sensor, may include a pixel array including a plurality of unit pixels, each of the plurality of unit pixels having a charge transfer unit for transferring charges accumulated in an optoelectronic converter to a charge detector via a charge transfer driving signal. The example image sensor may further include a row driving unit generating a boosted voltage, the boosted voltage set to a boosted voltage level higher than a power voltage level, the boosted voltage selectively boosted in response to a boosting voltage variable control signal. The row driving unit may selectively apply the charge transfer driving signal to the pixel array. In another example, the method may include selectively adjusting a voltage level of a charge transfer driving voltage and transferring the charge transfer driving voltage to a charge transfer unit for controlling an operation of the charge transfer unit.

Abstract: A horizontal charge coupled device (CCD) driving circuit, a solid-state image-sensing device having the same, and a method of driving the solid-state image-sensing device, transmits image signals using horizontal driving signals having a middle voltage during rising and falling of the horizontal signals. The middle voltage of the horizontal driving signals is generated when an equipotential switch is turned “on” while the output nodes of buffer circuits are in a floating state.
