发明名称 Autofocus system
摘要 <p>Two imaging elements (26A, 26B) for AF, each having a different optical path length, are mounted to a camera main body (10). The automatic focus adjustment is performed based on the video signal of the AF area extracted by the gate circuits (52A, 52B) from the video signal acquired by the imaging elements (26A, 26B). The electronic shutter function of the imaging elements (26A, 26B) is controlled based on the video signal of the AF area extracted by the gate circuits (52A, 52B), so as to enable the exposure adjustment for the AF area to be performed. &lt;IMAGE&gt;</p>
