Lens alignment method, lens alignment device and camera

The invention discloses a lens alignment method, a lens alignment device and a camera. The lens alignment method comprises performing a scan (12) at a plurality of regions of interest of the lens to determine an optical characteristic (2a-2e) of each region of interest when adjusting the position of the lens relative to the imager. Convergence windows (3a-3e) of the respective regions of interest are determined on the basis of the optical characteristics (2a-2e), and the position (13) of the lens relative to the imager is adjusted on the basis of predetermined positions of the convergence windows relative to each other. 一种镜头对准方法、镜头对准装置以及摄像头。镜头对准方法包括在所述镜头的多个关注区域处执行扫描(12)，以在调整所述镜头相对于所述成像器的位置时确定各个关注区域的光学特性(2a至2e)。基于光学特性(2a至2e)确定各个关注区域的会聚窗口(3a至3e)，并且基于会聚窗口相对于彼此的预定位置调整镜头相对于成像器的位置(13)。
