Whether the jitter amplitude of power-off sub-device 100 is less than or equal to predetermined amplitude；Focusing module 16 is additionally operable to no presence of the people
The time control of face region is formed as device 20 and focuses.
It is appreciated that during auto-focusing, if there is face in shooting picture, showing the main part in shooting picture
It is divided into people, and most cases servant is in close shot position, focusing area during auto-focusing should select human face region, if now electricity
There is shake in sub-device 100, then can cause portrait fuzzy problem out of focus.If there is no face in shooting picture, now shoot
Main part in picture may be the scenic picture such as distant view, if now there is shake in electronic installation 100, scenery it is out of focus can
Energy property is less.Therefore, should first recognizing during shooting with the presence or absence of face in shooting picture, motion sensor is utilized when there is face
30 carry out the Detection of Stability of electronic installation 100 to improve the accuracy of focusing.

Rapid S161 can be realized that step S162 can realize that step S163 can by the first recognition unit 162 by the first control unit 161
To be realized by the first judging unit 163, step S164 can realize that step S165 can be by second by the second control unit 164
Recognition unit 165 realizes that step S166 can be realized by the second judging unit 166, and step S167 can be by confirmation focusing unit
167 realize.
In other words, the first control unit 181 is driven to focus lens 21 from nearly Jiao position to remote Jiao for controlling motor 22
Jiao is sought in position with the first step away from progressively movement；First recognition unit 162 is used to process each first step to focus lens 22 away from right
The cache image answered is to recognize human face region；First judging unit 163 is described to judge for processing the human face region
Whether the contrast of human face region there is the first flex point；Second control unit 164 is used to be controlled when there is first flex point
Motor 22 is driven and focus lens 21 are returned a step and with second step away to the remote burnt position movement, and the second step is away from less than institute
State the first step away from；Second recognition unit 165 is used to process each second step to focus lens 21 away from the corresponding cache image
To recognize human face region；Second judging unit 166 is used to process the human face region to judge the contrast of the human face region
Whether Second Inflexion Point is occurred；Confirm that focusing unit 167 is used to determine that imaging device 20 is focused when there is the Second Inflexion Point.
Specifically, incorporated by reference to Fig. 9, when electronic installation 100 is under steady statue, focus operation is proceeded by.Focusing
Eyeglass 21 starts to move a first step away from the meeting of imaging device 20 away from Jiao is sought, often with the first step to remote burnt position from nearly burnt position
The corresponding cache image of a frame is exported, recognizes the human face region in each frame buffer image with recognition unit 162, and by first
Judging unit 163 calculates the contrast of human face region.When contrast reaches highest, focus lens 21 may proceed to remote burnt position
Direction move a first step away from the contrast of a frame buffer image of reentrying.Electronic installation 100 finds the slow of current output
The contrast for depositing image has declined compared to the contrast of the cache image of previous frame and occur in that the first flex point, then, control
Motor processed 22 return a first step away from, and using less than the first step away from second step away from carrying out seeking Jiao, until find second turning
Focusing during point is completed.Wherein, the contrast of the human face region of a frame buffer image can be the difference of minimum brightness and maximum brightness,
Show to be located at focal position to focus lens 21 when the minimum brightness for calculating is maximum with the difference of maximum brightness, focusing is completed.
Thus, imaging device 20 is accurately focused and exports clearly image.In due to only calculating each frame buffer image
The data processed needed for electronic installation 100 in human face region, therefore focus process are less, and focusing time is also less.
