Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The embodiment of the present invention is in the criterion of initial status using face information as described rotating camera, whenever detect comprise default face information in the current captured image information of described rotating camera time, obtain the angle that user inputs; The preposition angle of described rotating camera is set to obtained angle; Thus achieve the preposition angle dynamically arranging rotating camera, and further ensure the accuracy of set preposition angle by recognition of face, improve the experience sense of user.The embodiment of the present invention additionally provides corresponding device, is described in detail respectively below.
embodiment one
First realization flow of the method that the angle that Fig. 1 shows the rotating camera that the embodiment of the present invention one provides is arranged; For convenience of explanation, illustrate only part related to the present invention.
In embodiments of the present invention, described method is applied to intelligent terminal, and described intelligent terminal is provided with rotating camera.A preferred exemplary of the rotating camera that Fig. 2 provides for the embodiment of the present invention.As shown in Figure 2, described rotating camera 3 detects its angle rotated by digital hall sensor 1; Wherein, described digital hall sensor 1 is arranged on the body of intelligent terminal 5, and the magnet 2 corresponding with described digital hall sensor 1 is arranged on the whirligig 4 at rotating camera 3 place, when camera is in absolute initial status, upward, N pole down in the S pole of described magnet 2; Described whirligig 4 can rotate around the body of the rotating shaft of self relative to intelligent terminal 5, thus drive the magnet 2 on it to rotate, magnet 2 is changed relative to the distance of described digital hall sensor 1, and the magnetic field intensity of the magnet 2 that digital hall sensor 1 detects also changes.According to the output valve of described digital hall sensor, the anglec of rotation of rotating camera can be obtained.Described intelligent terminal includes but not limited to smart mobile phone, panel computer, learning machine, intelligent vehicle-carried equipment etc.
As shown in Figure 1, described method comprises:
In step S101, when detect comprise default face information in the current captured image information of described rotating camera time, obtain the angle that user inputs.
In embodiments of the present invention, the angle that user inputs is the preposition angle of the rotating camera that will arrange, and is called for short preposition angle prevalue, and user inputs described angle by the mode such as manually selected or soft keyboard inputs.Under the mode manually selected, intelligent terminal arranges the interval range [80 °-110 °] interface showing selectable preposition angle and be preferably 80 ° to 110 ° in the angle of rotating camera.Arbitrary value during user can select [80 °-110 °] is as preposition angle prevalue.
After the angle receiving user's input, control rotating camera to rotate from initial angle, described initial angle is the angle value of rotating camera when being in configuration state definitely, namely the camera lens of described rotating camera and the concordant and camera lens of the fuselage of intelligent terminal are in the side, the back side of intelligent terminal, the anglec of rotation giving tacit consent to now rotating camera is initial angle, namely 0 °.When angle (i.e. the position of described preposition angle prevalue) that described rotating camera arrival user inputs, start described rotating camera and take in described angle, obtain current image information.
In embodiments of the present invention, when rotating camera is in rear configuration state, captured picture is upright picture, and when rotating camera is in initial status, captured picture is the picture stood upside down, and needs after image procossing, obtain upright image.And in object captured by camera, face can identifiedly be upright or stand upside down.The upper captured image information of the angle (i.e. preposition angle prevalue) that the embodiment of the present invention inputs user rotating camera carries out recognition of face, obtains the face information in image information; Then judge whether described face information is the face stood upside down; If so, then illustrate that the angle (i.e. the position of described lead position prevalue) that rotating camera inputs user was in initial status time upper, obtained the angle that user inputs.
In step s 102, the preposition angle of described rotating camera is set to obtained angle.
After getting the angle that user inputs, the preposition angle arranging described rotating camera is described angle.Wherein, the preposition angle arranging described rotating camera is that described angle is specially: when described rotating camera is positioned in described angle, obtain the output valve of digital hall sensor, and store described output valve, described output valve switches to the criterion of initial status as rotating camera.When the output valve of the digital hall sensor of follow-up acquisition is less than or equal to described output valve, can judge that described rotating camera is in initial status, thus achieve the preposition angle of dynamic conditioning rotating camera, and improve the accuracy of preposition angle setting.
Further, described method also comprises:
If when not comprising face information in described image information, then user's shooting is pointed out to comprise the image of face information.
Or if when the face information in described image information is not handstand, the angle that prompting user is current inputted is wrong.
Pass through above-mentioned steps, get face information after carrying out recognition of face after, according to the recognition result of face, provide different informations respectively, adjust accordingly with reminding user, the automaticity that the initial status further increasing rotating camera is arranged, greatly improves the experience sense of user.
The embodiment of the present invention is in the criterion of initial status using face information as described rotating camera, whenever detect comprise default face information in the current captured image information of described rotating camera time, obtain the angle that user inputs; The preposition angle of described rotating camera is set to obtained angle; Thus achieve the preposition angle dynamically arranging rotating camera, make user that the preposition angle of rotating camera can be set according to the demand of oneself, and further ensured the accuracy of set preposition angle by recognition of face, improve the experience sense of user.

In embodiments of the present invention, the state of rotating camera comprises initial status and rear configuration state, and the corresponding angle of the rotating camera arranged that needs comprises preposition angle and rearmounted angle.
As shown in Figure 3, described method comprises step S301-S302, and wherein, step S301-S302 is identical with the step S101-S102 described in Fig. 1 embodiment, specifically refers to the description of above-described embodiment, repeats no more herein.
Described method also comprises:
In step S303, calculate the difference between described preposition angle and predetermined angle.
In embodiments of the present invention, pre-set an angle, as between the buffer zone between preposition angle and rearmounted angle, described predetermined angle is less than described preposition angle.After getting preposition angle, described preposition angle is deducted predetermined angle, its difference is rearmounted angle prevalue.Exemplarily, described predetermined angle can be 10 °, 20 ° etc.
In step s 304, the rearmounted angle of described rotating camera is set to described difference.
After getting rearmounted angle prevalue, control described rotating camera and rotate the described rearmounted angle prevalue of arrival, the output valve of digital hall sensor under acquisition current location, and store described output valve, described output valve switches to the criterion of rear configuration state as rotating camera.When the output valve of the digital hall sensor of follow-up acquisition is more than or equal to described output valve, judge that described rotating camera is in rear configuration state, thus achieve the rearmounted angle of dynamic conditioning rotating camera.
