The lens position selection section determines whether or not the intensity is smaller than a given threshold value when the phase difference calculation section cannot detect the phase difference, selects the near point-side lens position when the lens position selection section has determined that the intensity is smaller than the threshold value, and selects the far point-side lens position when the lens position selection section has determined that the intensity is larger than the threshold value.. ...
