Step S304, calculates sight line focal position in screen according to optical data；
Here, in the process being embodied as can the eyeball image of monitor in real time user, real-time renewal sight line focal position in screen, the wherein focusing of sight line focal position in screen and photographic head；
Step S305, transforms into coordinate points by sight line focal position in screen, and shows described coordinate points on screen；
Here, the concrete process that the present embodiment step produces includes: 1) when there being position to move, and the position that sight line moves to is the focusing position that current photographic head to carry out focusing, and triggers photographic head this point is focused in real time；2) record the position that the upper sight line of this position finally stops to focus when sight line moves to the position of button pair of taking pictures and take pictures；3) then keep when sight line remains stationary as current focusing to focus, and detect whether current location correctly focuses。
Step 306, detects whether to stop the operation that eye control is taken pictures, and when being, shoots photo；Otherwise, enter step S302。
Here, stop the operation that eye control is taken pictures, time namely the position of pupil and cornerwise center coincide together in eyes image, be and stop the operation that eye control is taken pictures, at this moment, start photographic head and take pictures。
The embodiment of the present invention achieves eye control function, focused by real-time tracking eyes, and then complete to take pictures, thus provide a kind of when user cannot be carried out bimanualness complete to take pictures action time can shoot the solution of perfect photo, namely undertaken focusing and taking pictures by eye control, keep but the stability of subordinate mobile phone photograph。
Above-mentioned step S301 to step S306 realizes such as through the processor in electronic equipment such as mobile phone, panel computer。
The present embodiment it is critical that analyze the eyes image that obtained by front-facing camera, obtain optical data；Then the direction of human eye, image space in imageing sensor (sensor) and the layout scenarios of eyes is analyzed according to optical data；And process, complete the determination of direction of visual lines, be just specifically described how lower sight line is analyzed below。
1) direction of visual lines is determined；
First, as shown in figure 3-2, eyes are abstracted as a geometric model, it is used for calculating offset distance and the offset direction of cornerwise center (coordinate 1) at pupil position (i.e. coordinate 2) the distance canthus of eyes, then generates offset vector according to offset distance and offset directionThen, the cornerwise center diagonal of canthus (dashed lines 31 in Fig. 3-2 be) at abstract canthus is labeled as coordinate 1；The crystalline lens profile information of eyes is determined the center of pupil again, wherein the center of pupil can be the geometric center position (this geometric center position mark is coordinate 2) of pupil, it should be noted that, due to the impact of the gene of people or other extraneous factors, crystalline lens will not be fully exposed so forming a circle completed for computational geometry center when needing by the part of algorithm polishing disappearance。When coordinate 1 and coordinate 2 overlap time, 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 shown in Fig. 3-3, when coordinate 1 and coordinate 2 offset, then need to calculate offset vector32 (offset direction and offset distances)。
By calculating this offset vectorValue and determine the sight line of user focal position in screen in conjunction with current eyes position in present image, focal position is shown on screen。It should be noted that above-mentioned displacement vector is the offset vector after crystalline lens imaging, the distance of skew is less, needs suitable weighting to amplify when calculating。
2) eye-observation position；
The offset vector of known sight line, so now it needs to be determined that eye-observation position: as shown in Figure 3-4, if the image information that preview obtains is abstracted on the screen of display screen of electronic equipment, so the position of human eye can be calculated by other Vector Message, assuming that be the initial point of vector by centrally disposed the 33 of screen, then between the center (central point 34 of the line between two eye pupil holes) of initial point and eyes, directive line is exactly eyes displacement vectors in screenIn conjunction with this displacement vectorOffset vector with sight lineCalculate sight line focal position in screen。
Give an example: (be labeled as when eyes are in this state of " position 1 "), and the offset vector that eye position calculates isDue to eyes position natively on the lower, even if so observation center also needs sight line to look up, so the vector washout produced when calculating sight line stop place coordinate and needing expression in the eyes view screen center in namely is fallen, obtain a real vector value(m, n are the amplification coefficient of vector), passes through vectorFinally determine sight line focal position in screen。
Certainly, this can't determine sight line stop place accurately, because needing coupling and debugging m, n the two amplification coefficient in realizing process, thus obtaining determining position more accurately and making user reach more real eye control experience。
This focusing being only through eye control functional realiey and camera function, simultaneously, the interface that can provide interface that the data of eye control function export and functional switch calls for third-party application, promote the regarded as output controlling that this function is used by third party APP developer, the use field of this function abundant, developing the application of more more characteristic, the mobile phone increasing user uses enjoyment。
The application scenarios of the present embodiment and income effect: based on the present embodiment, user has more stable experience of taking pictures when using one hand to take pictures, positioned by eye control, the purpose of real realization " where seeing just to where focusing ", the convenience and experience of better taking pictures taken pictures to the user with the hands taken pictures can not be made to provide, even those temporarily cannot extract out the user that both hands take pictures too increase the operating experience-one hand of user and also can take a self-defined focusing, it does not have the photo of shake；The present embodiment is also a function characteristic in current phone competition, can publicize as a bright spot, thus increasing the recreational experience taken pictures, simultaneously can also realize some other operation according to preposition eye control function, interface can be provided to third party developer simultaneously, develop some relative functions the APP (application program) of amusement type, thus increasing the use enjoyment of eye control。
