Lens driving apparatus and lens driving method

A lens driving apparatus comprising:

• a count pulse generation unit that generates a count pulse signal according to an operation of an operation member;
• a count pulse signal detection unit that detects the generated count pulse signal;
• a lens driving unit which moves a lens in correspondence with the number of input drive pulses;
• and
• a lens driving control unit that controls the number of the drive pulses input to the lens drive unit according to the detected count pulse signal,
• wherein the lens driving control unit controls the number of drive pulses with respect to the count pulse signal so that the number of drive pulses is different between a time period within an initial count detection time period for the detected count pulse signal and a time period after the initial count signal detection time period.

A method for driving a lens, the method comprising:

• detecting a signal output when an operation member is operated, by using a signal detection unit;
• controlling a drive signal input to a lens driving unit according to the detected detection signal, by using a lens driving control unit;
• and
• driving a lens according to the input drive signal, by using the lens driving unit,
• wherein the lens driving control unit performs a control for setting an amount for driving of the lens performed according to the drive signal based on the detection signal so that the amount for driving of the lens for driving of the lens for a time period after the initial signal detection time period is larger than the amount for a time period within the initial signal detection time period for the detection signal.
