In another embodiment of the disclosure, as shown in Figure 2, above-mentioned steps S101 can comprise the following steps.

In step S1011, obtain and carry out taking the reference picture in front described terminal view finder to described destination object.

At present, common electronic device terminal, when taking, capital presents the image in viewfinder range in real time, such as: for mobile phone, directly show the image in current viewfinder range on a display of the handset, for digital camera or DV video tape recorder, also can image in the current viewfinder range of electronical display screen display thereon.

In this step, the image of acquisition can real scene image before terminal taking in camera, such as: can pass to the real scene image of display screen from camera the reference picture extracting a certain frame and get as this step.Certainly, the image that also terminal can be obtained after a certain subnormal shooting action is as reference image.

In step S1012, image procossing is carried out to described reference picture, determine the face orientation of destination object in described reference picture according to processing result image.

After getting real scene image, by means such as image procossing, the face of destination object in image can be identified, then by carrying out further image procossing to face, tell the face of destination object towards.

Destination object can be people, such as: the statue of ordinary people or people, also can be common animal, such as: cat, dog, horse etc.Because the face of different destination objects is different, so, in a particular application, the face orientation model of different target object can be set up in advance, and then in this step can by the result after image procossing and the face orientation model set up in advance are contrasted, to identify the face orientation of destination object.

In the disclosed embodiments, the face orientation of destination object can be the direction of relative termination, is namely reference substance with terminal, such as: with terminal camera place one side for front, or, with the shooting direction of camera for front, and with the relative the opposing party in front for rear.So just can make when the follow-up direction of illumination to light compensating lamp controls, can be reference substance with terminal equally, avoid occurring direction entanglement.Certainly, in other embodiments, the photographer of handheld terminal can also be selected for reference substance or other reference substance.

In other embodiment of the disclosure, the face orientation of destination object can also be the direction of relatively described reference picture, namely in the plane at reference picture place, be previously provided with reference frame, the face orientation being arranged in the destination object on reference picture like this can accurately be determined to obtain at this reference frame.

In another embodiment of the disclosure, as shown in Figure 3, above-mentioned steps S1012 can comprise the following steps.

In step S10121, feature identification is carried out to described reference picture, judge whether include facial characteristics in described reference picture.

In this step, feature recognition rule can be pre-set, so just can directly utilize feature recognition rule to carry out feature identification to reference picture.

In the disclosed embodiments, feature recognition rule can be human body face feature recognition rule, certainly considers the difference needs of user, can also increase or change feature recognition rule, such as: dog is taken, the facial characteristics recognition rule of dog can also be increased.

When including facial characteristics in described reference picture, in step S10122, face recognition being carried out to the facial characteristics in described reference picture, obtaining face recognition result.

Abovementioned steps S10121 identifies according to feature recognition rule, extracts the recognition result including the feature of face in image.But for the details parameter of each facial characteristics inside, also need to carry out further face recognition, to obtain the details parameter comprised in facial characteristics.

In one embodiment, as shown in Figure 4, this step S10123 can comprise the following steps:

In step s 11, extract the characteristic parameter of face in described facial characteristics, described characteristic parameter at least comprises: the perspective size of face.

Face refer to: ear, eyebrow, eye, nose and mouth, be shot for example with personage, when including personage facial in image, have wherein that one or more occur on face in the picture in these face at least.

In step s 12, according to the ratio in the calculation of characteristic parameters facial characteristics of face in described facial characteristics between face.

With terminal place plane for reference, the object size in the picture far away apart from this plane is less, and the object size in the picture nearer apart from this plane is larger.Like this, for front shooting personage, when facial orientation direction is different, the ratio between face is not identical yet, and when the face of the personage that is taken is just to camera, for the eyes in face, two eyes ratio is in the picture identical; For the ear in face, two ears ratio is in the picture also identical.When face's lateral face of the personage that is taken is to camera, two eyes ratio in the picture will change, and two ears may only have one to occur in the picture.

In step s 13, according to the ratio in described facial characteristics between face, determine the face orientation of described destination object.

By after the ratio that calculates in facial characteristics between face, according to the corresponding relation of the ratio between the face pre-set and face orientation, the face orientation of destination object can be determined.

Face orientation	The direction of illumination of light compensating lamp
		Relative termination is towards left	Relative termination is towards upper left
Relative termination is towards left	Relative termination is towards upper right
		Relative termination is in the face of terminal	Relative termination is towards just going up
……	……

In step S1022, in described mapping table, search the direction of illumination of the relatively described terminal of described default light compensating lamp according to the face orientation of described destination object.

According to upper table, in this step, the direction of illumination of terminal directly can be obtained by the mode of tabling look-up.

In an application mode, this step S1022 can comprise the following steps.

31), when the face orientation of described destination object is the direction, left of described terminal, determine that the direction of illumination of described default light compensating lamp is the direction, upper left side of described terminal.
