Embodiment
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, and obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Electronic equipment in the embodiment of the present invention refer to as mobile phone, panel computer, super this etc. moveable electronic equipment, have the advantages such as hand-holdable, portable, applicable user watches at an arbitrary position.
The schematic flow sheet of a kind of picture display control method as shown in Figure 1, this flow process can be performed by picture display control unit, can be arranged in the mobile electronic device such as mobile phone, panel computer.The concrete steps of this flow process comprise:
Step S101, obtains the image information that electronic equipment front-facing camera gathers, carries out recognition of face according to the image information collected.
Concrete, obtain the image information that electronic equipment gathers as the front-facing camera of mobile phone, panel computer etc., from described image information, carry out recognition of face, if there is no face in described image information, then do not carry out subsequent step.Wherein, obtain the image information that electronic equipment front-facing camera gathers, can according to setting cycle (as cycles such as setting 5s, 10s, herein can by user's free setting) control described electronic equipment front-facing camera and gather image information, and obtain the current image information collected, also can be that the front-facing camera controlling described electronic equipment immediately gathers image information, and obtains the current image information collected when detecting that the position of described electronic equipment changes.The position of described electronic equipment changes and refers to that the change in location such as movement, upset appear in electronic equipment.When user's face conversion direction, if the front-facing camera now also not arriving setting gathers cycle of image information, then user can mobile electronic device, and the position of electronic equipment changes, the identification of face can be re-started immediately, again obtain face features.
Step S102, according to the face features identified, determines face face direction.
Concrete, when identifying face features, if the face quantity identified is one, then determine the facial direction of described face according to the facial characteristics of the described face identified.If the face quantity identified is at least two, then according to the priority of each face identified, obtain the facial characteristics of the highest face of priority, according to the facial characteristics determination face face direction of the highest face of described priority, wherein, the priority of face is by carrying out recognition of face to the facial image collected in advance and arranging for the face characteristic identified, and stores in the electronic device.
But, if when the face quantity identified is at least two, the priority (not comprising the current face identified in the priority of the face namely prestored) or the priority of each face that really do not get each face identified are identical, then obtain each face meta of identifying in the facial characteristics of the face in centre position, according to the facial characteristics determination face face direction of the described face mediated.As shown in Figure 2 a kind of identifies the schematic diagram in face face direction, and the face features identified specifically can comprise mouth, nose and eyes on face, wherein according to the direction in mouth or nose points two eyes centre positions, determines face face direction.
Step S103, judges that whether described face face direction is consistent with the picture display direction of described electronic equipment screen, if so, then proceeds to step S105, if not, then proceed to step S104.
Step S104, is adjusted to consistent with described face face direction by the picture display direction of described electronic equipment screen.The picture display direction adjustment process of electronic equipment screen as shown in Figure 3 a and Figure 3 b shows, when judging that the picture display direction in described face face direction and described electronic equipment screen is inconsistent, as shown in fig. 3a, the display direction of screen is towards the upper side frame of screen, and the facial direction of the face identified is towards the left frame of screen, need the picture display process adjusting described electronic equipment screen.Adjusted to by the picture display direction of described electronic equipment screen as shown in Figure 3 b and show towards the left frame of screen, now after adjustment, described face face direction is consistent with the picture display direction of described electronic equipment screen.
Step S105, does not adjust the picture display direction of described electronic equipment screen.
Above-described embodiment shows, by the image information that the front-facing camera obtaining electronic equipment gathers, recognition of face is carried out to the image information collected, and then according to the face features identified, determine face face direction, finally judge that whether described face face direction is consistent with the picture display direction of described electronic equipment screen, if not, then the picture display direction of described electronic equipment screen is adjusted to consistent with described face face direction.The method provided by the embodiment of the present invention can be realized user and watch the direction of electronic equipment and the picture display direction consistance of electronic equipment screen, and the picture display direction of screen can be followed the change in face face direction and change.
Based on identical technical conceive, the embodiment of the present invention also provides a kind of picture display control unit, and this device can perform said method embodiment.As shown in Figure 4, concrete implementation process repeats no more the device that the embodiment of the present invention provides.This device comprises:
