A receiving apparatus and method for a synchronizing process in the digital communication system is disclosed. The pixel reset operation is processing in which a photodiode corresponding to one of transfer transistors is reset. In operation, the voltage clamp unit generates a voltage of a low dependency on a supply voltage and clamps the generated voltage to a voltage level which, within a tolerable range, is lower than a single supply voltage externally furnished. The control system can have a first configuration for which the drive link is operatively coupled to the first and second deployable lift devices, and activation of at least a portion of the drive link moves the first and second deployable lift devices together.
