Title
(EN) Imaging device and focusing control method of imaging device
(ZH) 摄像装置及摄像装置的对焦控制方法
Abstract
(EN)
The present invention provides an imaging device capable of speeding up AF and a focusing control method of the imaging device. The imaging device is provided with a focus lens driving unit (16) for driving a focus lens (12); and an image sensor movement driving unit (120) for moving an image sensor (110) along an optical axis (L). A target position of the focus lens (12) for focusing on a subjectis set, and the focus lens (12) is moved toward the target position. Before the focus lens (12) reaches the target position, the image sensor (110) is moved and focused. After being focused, the image sensor (110) is moved so as to follow the focus lens (12) to maintain the focusing state.
