Auto-focusing apparatus

An auto-focusing apparatus comprising:

• a focus lens;
• a driving unit that drives the focus lens;
• an imaging device that receives an optical signal that has passed through the focus lens and generates an image signal;
• a focus evaluation value calculating unit that calculates focus evaluation values related to a focus state from the image signal;
• a peak position detecting unit that detects a target position of the focus lens corresponding to a peak of the focus evaluation values;
• and
• an operation unit that performs a prediction operation with respect to a moving object by using the peak position obtained by the focus lens in only a first direction.
