发明名称 IMAGING APPARATUS AND FOCUS CONTROL METHOD THEREFOR
摘要 PROBLEM TO BE SOLVED: To shorten time to obtain focus by avoiding malfunction of a TV-AF control.SOLUTION: An imaging apparatus comprises: an imaging device 106 for photo-electric conversion of a subject image formed by an imaging optical system comprising a focus lens 105; first detection means 113 for outputting focus evaluation value signals showing a focusing state of the imaging optical system on the basis of a high frequency component of outputting signals of the imaging device; second detection means 126 for outputting detection signals different from the focus evaluation value signals; and control means 114 for performing first processing for obtaining information for searching for a focusing position of the focus lens on the basis of the focus evaluation value signals. The control means performs second processing for obtaining information related to the focusing position of the focus lens on the basis of the detection signals from the second detection means, and performs different processing corresponding to the result of comparison between the information obtained by the first processing and the information obtained by the second processing.
