Abstract
A imaging-device driving unit, comprising a signal generator, a detector, and a controller, is provided. The imaging-device driving unit drives an imaging device that has a charge-transfer channel. The charge-transfer channel transfers the signal charges at a speed according to a frequency of a channel-driving signal. The signal generator generates one among a normal transfer signal, and a first and second discharge signals. The first discharge signal is the channel-driving signal whose frequency is determined for discharging an electrical charge remaining in the charge-transfer channel and greater than that of the normal transfer signal. The detector detects a remaining power. The controller orders the signal generator to generate the first discharge signal if the electrical charges remaining in the charge-transfer channel should be discharged and the remaining power is less than a threshold.
