The first face information：The eye shape information of who object and mouth shapes information.Specifically, electronic equipment is known by face
Multiple coordinate points that Huo get be on the eyes of who object, the line of multiple coordinate points represent eye shape, same mouth shape
Shape can also represent mouth shapes by the line of multiple coordinate points on mouth.It is next after the first face information is extracted
Moment obtains the second preview image for including acquisition target, and extracts corresponding second face information：Eye shape information and mouth
And then portion's shape information, judges whether the second face information is identical with the first face information.
Such as：Assuming that the personage's A expressions being taken at the first acquisition moment are dignified, eyes in the first face information of extraction
The arc that shape is the arc of 35 radians, mouth shapes are 10 radians, and the personage A being taken at the second acquisition moment likes smiling face
It opens, the arc that eye shape is the arc of 20 radians in the second face information of extraction, mouth shapes are 28 radians, then judge
Go out front and rear eye shape and differ 15 degree, 18 degree of front and rear mouth shapes difference, then judge the first face information and the second face
The diversity factor of information has been more than given threshold 8 for 15 and 18, therefore judges the second face information with the first face information not
It is identical, show that the expression of who object is largely changed, user may need to shoot photo, electronic equipment at this time
Automatic shooting preserves the second preview image.
Under " expression burst mode ", when the expression for the who object being taken persistently changes, electronic equipment then can
The photo of who object difference expression is automatically taken, such as smiles to laugh, laugh to funny face, funny face to face of crying, it is no longer necessary to
Reference object keeps each expression that photographer is waited for press shutter and takes corresponding photo, but micro- under automatic continuous shooting
Laugh at, laugh, the photo of funny face and face of crying, having provided more intelligent more efficiently image acquisition mode to the user, at the same avoid due to
The who object that is taken expression shape change is too fast and the problem of shoot less than corresponding photo.
(2), the first image information is the first movable information
User is in the preset mode for opening electronic equipment image acquisition units --- when " action burst mode ", electronic equipment
The first preview image is obtained by image acquisition units, recognition of face is carried out to the first preview image, extracts the first preview image

Action.Subsequent time after the first action message is extracted obtains the second preview image for including acquisition target, and extraction pair
The second action message answered, such as the second form of who object hand and the second position.And then, judge the second action message and the
Whether one action message is identical.
Such as：Assuming that the hand of personage A being taken at the first acquisition moment naturally droops, the first form of extraction is represents
The vector naturally drooped（0, -10）, first position be that coordinate points of the finger in the first preview image are（50,50）, and
For the hand fork of personage A that two acquisition moment were taken on waist, the first form of extraction is to represent the vector of bending（0, -4）, second
Position is that coordinate points of the finger in the second preview image are（80,40）, then judge the difference of the first form and the second form
Different is 6, the difference of first position and the second position is 3（30/10）It has been more than given threshold 1, therefore has judged the second action
Information is differed with the first action message, shows that the limb action of who object is largely changed, at this time user
It may need to shoot photo, electronic equipment automatic shooting preserves the second preview image.At " action burst mode ", electronic equipment
Whether the limb action of automatic decision subject changes, and when changing, then automatically snaps the photo of action transformation.

When preset quantity, stop to preserve the second preview image after the second acquisition moment, and by the preservation number of the second preview image
It is reset according to amount, in order to which user continues to obtain the figure changed when opening electronic equipment next time and obtaining modified-image function automatically
Picture；When the preservation quantity of the second preview image is less than preset quantity, the above-mentioned steps for repeating the application continue to automatically save change
The image of change.
Such as：User A opens " the expression burst mode " of electronic equipment when taking pictures to child B, and electronic equipment is automatic
The preservation quantity for preserving the second preview image of 13 points of 15 minutes start recordings preservation of first face image of crying of child B is 1, false
If preset duration is 1min, preset quantity 6, then electronic equipment is by the face of the detection child B in 13 points of 1min after 15 minutes
Portion's expression shape change image, when electronic equipment preserves the 6th the second preview image, the preservation quantity of record is 6, is judged at this time
Go out 6 not less than preset quantity 6, then the second preview image progress image information that electronic equipment stops automatically to subsequent time carries
It takes and preserves.Certainly preset duration in the past after, electronic equipment also stop automatically to the second preview image of subsequent time into
Row image information is extracted and is preserved, in order to reduce the power consumption of electronic equipment.
