    • A continuous focusing method for a digital camera is described, which is applicable to determine whether the digital camera performs a focusing procedure or not when the digital camera switches from a first scene to a second scene in a live view stage. The continuous focusing method includes the following steps. A preview image of a second scene is obtained. A blur detection procedure is performed on the preview image, so as to acquire a corresponding focus value. It is determined whether the focus value exceeds a focusing threshold value or not; if not, a focusing procedure is performed; otherwise, if the focus value is greater than the focusing threshold value, the digital camera still maintains a current focusing focal length, which represents that a focusing focal length of the second scene is the same as that of the first scene.
    • 描述了用于数字照相机的连续聚焦方法,其可应用于当数字照相机在实时显示阶段从第一场景切换到第二场景时,确定数字照相机是否执行聚焦程序。 连续聚焦方法包括以下步骤。 获得第二场景的预览图像。 对预览图像执行模糊检测过程,以获得相应的聚焦值。 确定焦点值是否超过聚焦阈值; 如果不是,则进行聚焦过程; 否则,如果聚焦值大于聚焦阈值,则数字照相机仍保持当前聚焦焦距,其表示第二场景的聚焦焦距与第一场景相同。
