Focal position.
Further, the Focusing parameter value that preset requirement is determined for compliance with from the Focusing parameter value includes：From institute
It states and determines the maximum Focusing parameter value of numerical value in Focusing parameter value；It is described to correspond to the Focusing parameter value for meeting preset requirement
The location of the eyeglass of autofocus lens be determined as focal position and include：By the maximum Focusing parameter value pair of the numerical value
The location of eyeglass of autofocus lens answered is determined as focal position.Specifically, during manual focus, user
Autofocus lens are adjusted to a direction, the image in view-finder can become gradually clear from fuzzy, and processor determines each
The corresponding Focusing parameter value of frame image, Focusing parameter value becomes larger, and when reaching focus state, continues to adjust auto-focusing mirror
Head, image can be from clearly becoming fuzzy, and Focusing parameter value can taper into.Processor can be by each frame image in focus process
Corresponding Focusing parameter value saves, and determines the maximum Focusing parameter value of numerical value in focus process according to preset strategy.
For example, as shown in fig. 6, when the corresponding Focusing parameter value of S1 frame images that processor determines is y1, S2 frame images are corresponding
Focusing parameter value is when falling to y2, when the corresponding Focusing parameter value of S3 frame images is y3, when detecting two continuous frames image
When corresponding Focusing parameter value continuously declines, it may be determined that the corresponding Focusing parameter value of S1 frame images is the maximum focusing ginseng of numerical value
Numerical value；Or work as and detect that the corresponding Focusing parameter value of continuous two field pictures continuously declines, and fall (i.e. y1-y2,
When y2-y3) more than predetermined amplitude value, it may be determined that the corresponding Focusing parameter value of S1 frame images is the maximum Focusing parameter of numerical value
Value.After the maximum Focusing parameter of numerical value is determined, you can with the maximum Focusing parameter value of the numerical value is corresponding automatic right
The location of eyeglass of zoom lens is determined as focal position.
It should be noted that those skilled in the art can also use other strategies to determine that numerical value is maximum in focus process
Focusing parameter value, does not limit specifically herein.
