Autofocus device, imaging device and camera system |
摘要 |
<p>When a camera lens is in the midst of pan operation or tilt operation and in an autofocusingmode (AFmode) (step S101), not normal autofocus processing, but wobbling AF processing (step S103) is carried out to move a focus lens constituting the camera lens forwardly or backwardly while oscillating the position of the focus lens forwardly/backwardly, and search the peak position of the high-frequency component value in an image signal picked up through the camera lens. Accordingly, the focus position can be searched with high precision even under operation. <IMAGE></p> |
