发明名称 Lens apparatus, imaging apparatus and automatic focusing control method
摘要 <p>A lens apparatus (101) capable of carrying out a suitable AF control operation even when text or character information is superimposed on a video signal is provided. The lens apparatus is configured to generate first and second AF evaluation values from a video signal obtained from an imaging unit of a camera apparatus, and to perform focusing control based on the second AF evaluation value.
