Fig. 3 and Fig. 6 is referred to, in some embodiments, first position can be remote burnt position, and the second place can be
Nearly burnt position.
In some embodiments, imaging device 200 may include Front camera 250, and Front camera 250 can be used for user certainly
Clap.The focusing control method of embodiment of the present invention can be applied to the self-timer of Front camera 250.During self-timer, because user holds
Imaging device 200 is substantially in 30~50cm to the face to oneself, the distance of camera lens 210 to the face of user of imaging device 200
Scope, be generally 40cm or so.Therefore the camera lens 210 of imaging device 200 can be preset in nearly Jiao before taking pictures
Position, so, save on the time that camera lens 210 is moved to nearly burnt position from remote burnt position.
Referring to Fig. 6, however, user is when using the front camera self-timer of imaging device 200, it is possible to can use certainly
Dabber 2000, therefore the distance of camera lens 210 to face 3000 is possible in 1m~1.5m.In fact, it is if higher in ambient brightness
Daytime when, Front camera 250 is shot using less aperture, and the depth of field is wider, and to object distance, (i.e. face 3000 arrives camera lens 210
Distance) there is larger accommodation, that is to say, that 40cm can be adapted to simultaneously in the case of without significantly moving lens 210
Nearly Jiao of left and right takes pictures and more than 1m remote Jiao takes pictures and takes clear photograph.
But when ambient brightness is relatively low, often aperture is tuned up to lift brightness of image and definition, and reduce and make an uproar
Point.Aperture tunes up to narrow along with the depth of field, and the accommodation of object distance is also narrowed.Now, according to longer self-shooting bar 2000
Self-timer, and when camera lens 210 is located at nearly burnt position, image blur can be caused.
In the focusing control method of embodiment of the present invention, when camera lens 210 is located at remote burnt position (i.e. first position),
If detecting, the contrast grade of preview image is less than or equal to predetermined contrast grade, and camera lens 210 is moved on into nearly burnt position (i.e. second
Put).That is, system default only has two kinds of situations, i.e., user holds the self-timer of imaging device 200, or uses longer self-timer
The self-timer of bar 2000.Since either-or, when being unsatisfactory for contrast grade requirement in first position, then automatically the second place is defined as closing
Burnt position.In this way, focusing time and photo opporunity can be greatlyd save, and it can preferably meet the hand-held self-timer and self-shooting bar of user
The shooting style of 2000 self-timers.
Fig. 7-8 are referred to, in the focusing control method of some embodiments, using the self-shooting bar of adjustable length
2000；Self-shooting bar 2000 is used to send the current length of self-shooting bar 2000 to electronic installation after being connected with electronic installation 1000
1000；
S3 includes：
S301, judges whether the length of self-shooting bar 2000 is more than predetermined length；
S302a, if so, camera lens is arranged at into first position to complete to focus；
S302b, if it is not, camera lens is arranged at into the second place to complete to focus.
S301, S302a, S302b can be by the first setup modules 130 of the focusing control apparatus 100 of some embodiments
Second judging submodule 131 and setting submodule 132 are realized.That is, the second judging submodule 131 is used to judge self-shooting bar
Whether 2000 length are more than predetermined length.Submodule 132 is set to be used for mirror when the length of self-shooting bar 2000 is more than predetermined length
Head is arranged at first position to complete to focus, or for setting camera lens when the length of self-shooting bar 2000 is less than or equal to predetermined length
In the second place to complete to focus.
Because some self-shooting bars 2000 have the function of telescopic adjustment length, after it is connected with electronic installation 1000, need
Detect its length could judge camera lens being arranged at first position or the second place it is more suitable.It can be set on self-shooting bar 2000
For sensing or recording the sensor of the length of self-shooting bar 2000, such as the measurement that the motor flexible with control self-shooting bar 2000 couples
Device, the distance that motor rotates can be converted into the current length of self-shooting bar 2000.Again by transmission means such as bluetooths by self-timer
The length data of bar 2000 is sent to electronic installation 1000.
If the length of self-shooting bar 2000 is more than predetermined length, such as 70cm, then camera lens can be moved to first position, such as remote burnt position
Put, if the length of self-shooting bar 2000 is not more than predetermined length, such as 70cm, then camera lens can be moved to the second place, such as near burnt position.
In this way, most suitable lens location can be selected according to the physical length of self-shooting bar 2000, so as to rapid focus, take clearly according to
Piece.
Referring to Fig. 9, in some embodiments, imaging sensor 230 includes photosensitive pixel array 231.Imaging device
200 are used to merge the output of multiple photosensitive pixels 2331 with a pixel of corresponding preview image.
For example, it may include optical filter and the photosensitive pixel array 231 relative with optical filter, optical filter in imaging device 200
On have filter array 233, filter array 233 is made up of the filter unit 2331 of multiple different colours, for example, by red (R),
Green (R), the filter unit 2331 of blue (B) color form.Each filter unit 2331 can correspond to multiple photosensitive pixels 2331, such as
It is corresponding four, the output of photosensitive pixel 2331 corresponding to same filter unit 2331 can be merged into and merge pixel output, and it is right
Answer a pixel of generated image.
In this way, can be lifted in shooting brightness and the definition of imaging, especially night take pictures or low luminous environment under take pictures
When, noise can be reduced, and image quality lifting is more apparent.In actual applications, especially when clapping at night, if aperture be arranged on F2.0 with
On, when being taken pictures with more than one meter of self-shooting bar 2000, rapid focus is unable to according to traditional focusing mode shooting style, so as to
Easily clap and must obscure, using the focusing control method of embodiment of the present invention, rapid focus and more visible photo can be taken.
