Embodiment three
The present embodiment will provide a kind of information processing method, and this method is to realize to clap using the method analyzed by pure software
The function of taking out perfect photo, without increasing hardware cost.Fig. 3-1 is the realization stream of three information processing method of the embodiment of the present invention
Journey schematic diagram, as shown in figure 3-1, the detailed process of the embodiment includes:
Step S301 when opening rear camera and taking pictures while opening front camera；
Step S302 obtains the eyes image of user by front camera；
Step S303 analyzes the eyes image when getting the eyes image of user, obtains eye number
According to；
Specifically, the eyes image is analyzed, the line between the pupil position of eyes, the pupil position of eyes is obtained
Center position (center position abbreviation center), the center position of screen a series of optical data such as work as；
Step S304 calculates focal position of the sight in screen according to optical data；
Here, the eyeball image of user can be monitored in real time during specific implementation, sight is updated in real time and shielding
Focal position in curtain, wherein focal position, that is, camera focus point of the sight in screen；
Focal position of the sight in screen is transformed into coordinate points, and shows the seat on the screen by step S305
Punctuate；
Here, the specific process that the present embodiment step generates include: 1) when there is position mobile, what sight was moved to
Position is to work as the focusing position that preceding camera is focused, and trigger camera and focused in real time to the point；2) when
It is focused simultaneously the position that sight records this position upper sight when being moved to the position for button pair of taking pictures finally stops
It takes pictures；3) it then keeps current focus point to focus when sight remains stationary, and detects whether current location correctly focuses.
Step 306, it detects whether to stop the operation that eye control is taken pictures, when being, shoots photo；Conversely, entering step S302.
Here, stop the operation that eye control is taken pictures, i.e., the position of pupil is overlapped with cornerwise center in eyes image
When together, at this moment the operation that as stopping eye control is taken pictures starts camera and takes pictures.
The embodiment of the present invention realizes eye control function, is focused by real-time tracking eyes, and then completes to take pictures, to mention
For a kind of solution that as user can not carry out that perfect photo can be shot when both hands operation is completed and takes pictures and act, that is, pass through
Eye control is focused and is taken pictures, the stability of holding but subordinate mobile phone photograph.
Above-mentioned step S301 to step S306 can by the processor in electronic equipment such as mobile phone, tablet computer come
It realizes.
The present embodiment it is critical that the eyes image that is obtained by front camera of analysis, obtains optical data；Then
The direction of human eye, the layout scenarios of imaging position and eyes in imaging sensor (sensor) are analyzed according to optical data；
And handled, to complete the determination of direction of visual lines, just it is specifically described how lower sight is analyzed below.
1) direction of visual lines is determined；
Firstly, as shown in figure 3-2, eyes are abstracted as a geometrical model, for calculating the pupil position of eyes (i.e.
Coordinate 2) cornerwise center (coordinate 1) apart from canthus offset distance and offset direction, then according to offset distance
Offset vector is generated from offset directionThen, it is abstracted cornerwise center (dotted line line in Fig. 3-2 at canthus
Item 31 is the diagonal line at canthus) it is labeled as coordinate 1；The crystalline lens profile information of eyes is determined to the center of pupil again,
Wherein the center of pupil can be the geometric center position (the geometric center position mark is coordinate 2) of pupil, need
It is bright, due to the influence of the gene of people or other extraneous factors, crystalline lens will not be fully exposed thus needs when
It waits and is used to computational geometry center with the circle that the part that algorithm polishing lacks forms a completion.It is overlapped when coordinate 1 and coordinate 2
When, then it is assumed that the position that expression in the eyes is watched attentively is right-angle view current information (or can be regarded as observation center).As Fig. 3-3 institute
Show, when coordinate 1 and coordinate 2 are offset, then needs to calculate offset vector32 (offset direction and offset distances).
By calculating this offset vectorValue and determine use in conjunction with position of the current eyes in present image
Focal position of the sight at family in screen, focal position is displayed on the screen.It should be noted that above-mentioned displacement vector
It is the offset vector after crystalline lens imaging, the distance of offset is smaller, and weighting appropriate is needed to amplify when calculating.
2) eye-observation position；
The offset vector of known sight, then now it needs to be determined that eye-observation position: as shown in Figure 3-4, if by preview
The image information of acquisition is abstracted on the screen of the display screen of electronic equipment, then the position of human eye can pass through other vector
Information is calculated, it is assumed that is the origin of vector by the center setting 33 of screen, then the center (two of origin and eyes
The central point 34 of line between pupil) between directive line be exactly displacement vector of the eyes in screenIn conjunction with
This displacement vectorWith the offset vector of sightCalculate focal position of the sight in screen.
For example for: when this state that eyes are in " position 1 " (is labeled as), and what eye position calculated
Offset vector isDue to eyes position natively on the lower, so even if observation center is also that sight is needed to look up,
So calculate sight stop place coordinate i.e. when need expression in the eyes viewing screen center when the vector washout that generates
Fall, obtains a true vector value(amplification coefficient that m, n are vector), passes through vectorIt is final true
Determine focal position of the sight in screen.
Certainly, this can't accurately determine sight stop place, because needing to match and debug m, n during realization
The two amplification coefficients, to obtain more accurate determination position and user is made to reach more true eye control experience.
This is only through the focusing of eye control function realization and camera function, meanwhile, the data that can provide eye control function are defeated
The interface of interface and functional switch out is called for third-party application, and third party APP developer is promoted to use this function
It expands and develops, that enriches this function uses field, develops the application of more more characteristics, increases the mobile phone the fun of using of user
The application scenarios and income effect of the present embodiment: being based on the present embodiment, and user is had more when being taken pictures using one hand
Stable experience of taking pictures, is positioned by eye control, really realizes the purpose of " where see just to where focus ", to cannot use pair
The user that hand is taken pictures provides the convenience taken pictures and experience of preferably taking pictures, those can not temporarily be extracted out with what both hands were taken pictures
Even operating experience-one hand that user also increases user can also take a customized focus point, the photo that do not shake；
The present embodiment is also to have a distinctive function in current phone competition, can be used as a bright spot and is publicized, to increase
Add the amusement sexual experience taken pictures, while can also realize some other operations according to preposition eye control function, while can mention
For interface to third party developer, develop some relative functions amusement type APP (application program), to increase
The fun of using of eye control.
