It is the functional block diagram of mobile terminal first embodiment of the present invention referring to Fig. 2, Fig. 2.It is described in the present embodiment Mobile terminal includes camera 300 and the camera 300 is the screen side that mobile terminal is arranged in, such as the preposition camera shooting of mobile phone Head.

In addition, the mobile terminal further include:

Head portrait monitoring modular 310, for being monitored by camera when at least one current primary user carries out picture browsing With the presence or absence of the head portrait entrance of other new users in current imaging area, wherein the head portrait of the primary user, new user head portrait It is not shown on the screen of the mobile terminal；

In the present embodiment, primary user is specifically mobile terminal owner or the use that monitors for the first time after camera starting Family, such as owner invite multiple user's browsing pictures simultaneously, then the primary user monitored for the first time when camera starts then includes Owner and its user invited.In addition, imaging area specifically refers to the region that camera 300 can take, specifically with take the photograph As first 300 hardware setting is related.Assume that the angular range that camera 300 can be shot is 0~180 ° in the present embodiment, namely As long as assuming that user before camera 300, is in the imaging area of camera 300, as shown in figure 3, using account As that can be taken by video camera 300 on position M, P, Q, N.

In addition, in the present embodiment, only when head portrait monitoring modular 310 detects use by camera 300 in imaging area It when head portrait (namely user passes through eyes browsing pictures) at family, can be determined as that browse graph is added there is currently other new users Piece, and it is same as the prior art for the mode of head portrait detection, therefore, do not do excessively repeating, such as face recognition technology etc..

In addition, in the present embodiment, the head portrait of all users taken by camera 300 is not in the screen of mobile terminal It is shown on curtain and is mutually conflicted to avoid with user's browsing pictures, but it should be recognized that mobile terminal is it is known that user The head portrait position coordinates in shown region on the screen.

Angle calcu-lation module 320, for there are the heads of other new users when being monitored in current imaging area by camera Folder when as entering, according to default calculation, where calculating the direction of visual lines and the screen of the new user between plane Angle；

Angle α where user's direction of visual lines as shown in Figure 4 and screen between plane.Angle calcu-lation mould in the present embodiment Block 320 specifically can calculate angle α according to preset calculation, and the specific implementation of the calculation is unlimited.For example, can be by taking the photograph As first 300 calculate center's point of screen to the distance between user's head portrait c, then calculated in screen by camera 300 again The distance between plane a where heart point to user's head portrait, for example, generally from the screen of mobile terminal when due to user's browsing pictures Distance it is all close, therefore as user's body can be regarded to the plane where user's head portrait, thus according in right angled triangle Angle α=arccos (a/c) can be obtained in angle calculation formula.Or the position coordinates such as according to user's head portrait on the screen And the corresponding relationship between user's head portrait physical location calculates angle α.

Angle-determining module 330 is rotated, the picture for currently being browsed according to the angle and presently described primary user Browse mode determines the rotation angle of the picture currently browsed corresponding with the browse mode；

In the present embodiment, settable a variety of browse modes to be applicable in the different use demands of user, such as setting follow it is clear It lookes at mode, then can obtain optimal viewing experience (such as viewing picture when multiple user's browsing pictures in this mode Angle it is best)；Or the anti-peeping mode of setting, then it can be seen when user is in the mode browsing pictures to avoid by other users To the picture browsed, to protect the personal secrets of user.Therefore in the present embodiment, to realize above-mentioned different viewing modes Lower corresponding function then needs to determine by rotation angle-determining module 330 in different user's direction of visual lines and screen institute The corresponding rotation angle for needing picture rotation under angle between plane.

In general, when user's browsing pictures content, when only image content is towards user, user can just be browsed on picture Content, and when image content is not towards user, the content on picture can not be browsed in user.It therefore, can be according to above-mentioned Feature determines the angle for needing picture to be rotated corresponding to the different user angle α under different viewing modes.For example, when browsing Mode be anti-peeping mode when, if the content of the picture currently browsed towards user, when camera 300 detects other users , can be 180 ° by picture rotation when browsing is added, also picture is overturn, thus the content that browse to user can not on picture, And then the privacy to protect primary user.

Picture rotation control module 340 is revolved for controlling the picture currently browsed according to corresponding with the browse mode Turn direction and rotate the rotation angle, for new user's co-browse or prevents new user's browsing.

In the present embodiment, after rotating picture rotation angle corresponding to the determining new addition user of angle-determining module 330, The picture currently browsed can be controlled by picture rotation control module 340 according to the side of rotation corresponding with the browse mode of setting To rotating the rotation angle, for be newly added user's co-browse current image or prevent newly be added user peep it is primary The image content that family is browsed.In addition, it is necessary to explanation, rotation angle is specifically the picture start bit from control picture rotation It sets and starts calculating, and the setting of the initial position of picture rotation is unlimited, is configured with specific reference to actual needs, such as will figure Initial position when plane where piece is parallel with plane where screen as picture rotation, or by picture institute after last rotate In initial position of the angle position as this picture rotation.

Further alternative, the browse mode includes anti-peeping browse mode, tracking-browsing mode.Browse mode can be by User presets, for example the attribute for carrying out browse mode to file is arranged, then all pictures are in browsing under this document presss from both sides Corresponding browse mode is consistent with file.

In this alternative embodiment, under anti-peeping browse mode, it can prevent other users from peeping browsing by rotating image The image content that active user is browsed；And under tracking-browsing mode, it can be convenient for total between multiple users by rotating image With browsing pictures content and guarantee that each user has optimal browsing visual experience.

In the present embodiment, the rotation corresponding in the picture rotation that control currently browses of picture rotation control module 340 Direction is corresponding to the browse mode of current image.For example, if being currently anti-peeping browse mode, picture rotation control module 340 need to control image content be not displayed to the user being newly added namely picture rotation control module 340 control picture working as Place display position under preceding display position after the corresponding rotation angle of (such as image content face primary user) rotation, it is new to be added User will be unable to browse to image content, thus can correspond to determine the anti-peeping browse mode under picture rotation direction.

In the present embodiment, while user's browsing pictures, head portrait monitoring modular 310 is monitored whether by camera 300 There are the additions of new user, to realize the detection to other users.In addition, passing through angle meter after browsing is added in new user The angle and rotation angle calculated between horizontal plane where module 320 calculates the new direction of visual lines and screen that user is added determine mould Picture rotation angle determined by block 330, thus by picture rotation control module 340 control the picture that currently browses carry out with When the angle is rotated accordingly accordingly to realize multiple user's co-browse pictures, meet the browsing body of multiple user's different angles It tests, or prevents other users from peeping, to promote the usage experience during user's browsing pictures.

It is the refinement the functional block diagram of angle calcu-lation module in Fig. 2 referring to Fig. 5, Fig. 5.Based on the above embodiment, originally In embodiment, the angle calcu-lation module 320 includes:

Head portrait coordinate acquiring unit 3201 is new by the way that there are other in the current imaging area of camera monitoring for working as When the head portrait of user enters, the area coordinate of the head portrait of the new user on the screen is obtained, the area coordinate includes Head portrait represents coordinate；

In the present embodiment, the new head portrait that user is added is obtained in mobile terminal screen by head portrait coordinate acquiring unit 3201 On area coordinate, the head portrait of user A as shown in Figure 6 institute region on mobile terminal screen, it is assumed that screen upper left Angle O point be screen corresponding to XY axis two-dimensional coordinate system origin, then user's head portrait region can with coordinate A (x1, y1, x2, Y1 it) indicates, wherein x1, x2 are maximum corresponding to the head portrait of user A, minimum X axis coordinate；Y1, y1 correspond to maximum, minimum Y Axial coordinate.In addition, C point (c1, c2) is the central point of screen as shown in Figure 6, head portrait represents coordinate a point (x_a, y_a) it is preferably area The central point of domain coordinate A (x1, y1, x2, y1), naturally it is also possible to be other coordinate points in area coordinate A, such as X axis coordinate It is worth any one the smallest coordinate points.

Angle calcu-lation unit 3202 leads to for representing the center point coordinate of coordinate and the screen according to the head portrait Preset angle calcu-lation formula is crossed, the angle is calculated.

As shown in Figure 6, it is assumed that the line direction of the central point C point of user A and screen corresponds to the direction of visual lines of user, then Angle where angle β described in Fig. 7 corresponds to user's direction of visual lines and screen between plane.In the present embodiment especially by Following formula calculates angle β:

Angle β=90 °-k₁*(X₁/X₀) * 90 ° of formula 1；

Wherein, k₁For constant, X₁For head portrait represent the horizontal axis coordinate values of coordinate points to center's point of screen horizontal axis coordinate value it Between distance, X₀For the horizontal axis coordinate value of center's point of screen, the 1 calculated angle β of institute of formula is positive at this time；

In addition, in the present embodiment, since the head portrait of user is likely to appear in the left side or right side of center's point of screen, and The orientation that user's head portrait occurs is not can reflect in above-mentioned formula 1, and hence it is also possible to calculate especially by following equation 2 The relative angle γ of angle β, wherein relative angle γ indicates the folder between the direction of visual lines of user and the straight line of normal to screen Angle.

Relative angle γ=k₂*(X₂/X₀) * 90 ° of formula 2；

Wherein, k₂For constant, X₂The horizontal axis coordinate that head portrait represents coordinate points is subtracted for the horizontal axis coordinate value of center's point of screen Value, X₀For the horizontal axis coordinate value of center's point of screen, then the 2 calculated relative angle γ of institute of formula may be positive at this time, It may be negative value, for example when user's head portrait is on the left of screen, relative angle γ is positive, and is then negative at right side Value.

Optionally, k₁=1.By taking formula 1 as an example, as shown in Figure 3, it is assumed that the angular range that camera 300 can be shot is 0 ~180 °, then user can be taken on position M, P, Q, N by video camera 300.Wherein, user is at the position M, at this time X₁ It can regard as equal to X₀, then the angle β between user's direction of visual lines and screen place plane is 0 °；And user is at the position N, this When X₁It can regard as equal to X₀, then the angle β between user's direction of visual lines and screen place plane is 0 °；And user is in the position Q When, X at this time₁It can regard as equal to 0, then the angle β between user's direction of visual lines and screen place plane is 90 °, and user is in P Corresponding angle β=90 °-k when position₁*(X₁/X₀)*90°>0°。

Optionally, k₂=1.By taking formula 2 as an example, as shown in figure 3, user is at the position M, X at this time₂It can regard as equal to X₀, Then the relative angle γ between user's direction of visual lines and screen place plane is 90 °；And user is at the position N, X at this time₁It can be with It regards as and is equal to 2*X₀, then the relative angle γ between user's direction of visual lines and screen place plane is -90 °；And user is in the position Q When, X at this time₁It can regard as equal to 0, then the relative angle γ between user's direction of visual lines and screen place plane is 0 °；And it uses The family relative angle γ=k corresponding in P position₂*(X₂/X₀)*90°>0°.In this alternative embodiment, use formula 2 can be with The directly fixed picture rotation direction of setting, for example, picture rotates counterclockwise under anti-peeping browse mode, and it is clear following It lookes under mode, picture rotates clockwise.For example, if under anti-peeping browse mode, when detecting user's head portrait of P position, I.e. γ ° of relative angle > 0 ° when, can rotate counterclockwise at this time one be greater than zero angle, to prevent from being peeped；And if clear following It lookes under mode, then an angle for being greater than zero can be rotated clockwise, to allow user that optimal viewing angle can be obtained.

It is many for the mode for calculating angle in the present invention, and use is generated especially by camera 300 in the present embodiment The centre coordinate of screen area coordinate and screen corresponding to account picture, is then calculated by preset calculation formula. It should be noted that due to the change in location of user changes in coordinates on the screen corresponding with user's head portrait be not it is linear, But by test can approximation regard equal proportion linear change as, therefore, formula 1,2 obtained angles in the present embodiment are not Exact value, but approximation, thus can't be too big for the angular error for controlling picture rotation in the present invention, therefore above-mentioned meter It is feasible for calculating formula.

Further alternative, in one embodiment of mobile terminal of the present invention, the rotation angle-determining module 330 is specifically used In: if the browse mode for the picture that presently described primary user is browsed is anti-peeping browse mode, it is determined that the figure currently browsed The rotation angle of piece is equal to the angle；And if the browse mode of picture that presently described primary user is browsed is tracking-browsing Mode, it is determined that the rotation angle of the picture currently browsed is equal to complementary angle corresponding to the angle.

It is specifically illustrated, but not limited obtained by other formula with the angle calculated of formula 1 in the present embodiment The angle arrived, for example, calculate obtained related angle according to formula 2, then corresponding rotation angle also need to be based on it is opposite The same calculating benchmark of angle, does not do excessively repeat herein.

In general, when plane (image content towards user) is vertical with user's direction of visual lines where the picture, user's browse graph The visual effect of piece is best, and when the plane where the picture is parallel with user's direction of visual lines or user's sight can only see picture The back side when, can prevent user from peeping the content on picture.Therefore, which kind of formula angle and rotation are either calculated using Corner, as long as above-mentioned requirements can be reached, namely under anti-peeping browse mode, make user's direction of visual lines with it is postrotational Picture is parallel, and under tracking-browsing mode, keep user's direction of visual lines vertical with plane where picture.

In the present embodiment, if the browse mode for the picture that presently described primary user is browsed is anti-peeping browse mode, Determine that the rotation angle of the picture currently browsed is equal to the angle namely picture from normal browsing position (image content face Plane where user and picture is parallel with screen where screen or in the same plane) be after rotation angle identical with angle β It is parallel with user's direction of visual lines to may make plane where picture, or the rotation angle for being greater than angle β can also be rotated, from And user's sight is made to can only see the back side of picture and prevent other users from peeping, as shown in Figure 7.

In the present embodiment, if the browse mode for the picture that presently described primary user is browsed is tracking-browsing mode, really The rotation angle of the picture browsed before settled is equal to complementary angle corresponding to the angle.Namely picture (is schemed from normal browsing position Plane where piece content face user and picture is parallel with screen where screen or in the same plane) rotate it is remaining with angle β Plane where may make picture after the identical angle in angle (the sum of complementary angle and angle β are equal to 90 °) (image content towards user) It is vertical with user's direction of visual lines and make the angle of the available optimal browsing pictures of user, to improve more people's co-browses Usage experience when picture.

It is further alternative, if monitor that the head portrait of multiple new users enters by camera, control picture rotation 180 ° or control screen blank screen.This alternative embodiment is the control mode under special case, but the present invention can satisfy usually In the case of picture browsing demand.

The present embodiment, which is only paired into, calculates the lower corresponding picture rotation angle of angle formulae 1, but the present invention does not limit In the formula that other calculate angle and picture rotation angle.Furthermore, it is necessary to further illustrate, picture rotation in the present embodiment Corresponding rotation starting position is fixed when turning, and is all to calculate rotation angle since normal browsing position from picture, Namely the size of the rotation angle of picture corresponds to the corner dimension between picture place plane and screen place plane.In addition, Due to being that angle value is not offered as the direction rotated by the obtained picture rotation angle of angle calcu-lation formula 1, figure The direction of rotation of piece specifically needs related to area coordinate corresponding to the head portrait that user is newly added.For example, in anti-peeping browsing Under mode, if user's head portrait appears in the left side of center's point of screen, need to rotate counterclockwise, and it is clockwise if appearing in right side Rotation.

It is the functional block diagram of mobile terminal second embodiment of the present invention referring to Fig. 8, Fig. 8.Based on the above embodiment, In the present embodiment, the mobile terminal further include:

Initialization module 350, for when starting picture browsing, opening the camera and initialising subscriber list, institute User list is stated for saving the relevant information of user；

In the present embodiment, when user starts picture browsing application browsing pictures by mobile terminal, by initializing mould Block 350 opens camera 300, while initializing to user list, wherein user list { u1, u2, u3 ..., un } is used for Save the relevant information, such as entering order, angle β, the picture rotation angle of user's browsing pictures etc. of user.When initialization mould When 350 initialising subscriber list of block, user list initial value is sky.

User list module 360, for working as the head portrait monitored in current imaging area there are user by the camera Into when, the entering order of the user is numbered and by the Customs Assigned Number of the user and user's browsing pictures when is corresponding Picture rotation angle be saved in the user list；And exist when being monitored in current imaging area by the camera When the head portrait of user exits, deleted from the user list user Customs Assigned Number and the user corresponding to the picture Angle is rotated, and updates the Customs Assigned Number of the other users in the user list after user's entering order.

In the present embodiment, picture rotation angle is identical as the meaning of rotation angle in above-described embodiment namely control figure Piece rotates and makes user's direction of visual lines and rotation angle corresponding when screen vertical where picture.For the use in user list Family information is specially un { n, a }, wherein n indicates the number for user's entering order that camera 300 monitors, a indicates that user is clear Look at picture when corresponding picture rotation angle.

The user monitored in the present embodiment for camera 300 enters that there are two kinds of special cases:

Situation 1: camera 300 monitors multiple users for the first time while entering browsing pictures；In such situations, generally may be used Regarding as all users is all primary user, namely allows the user of browsing pictures, therefore all users monitored for the first time are seen It is numbered at a whole user and is 1 or serial number is 1,2,3 etc. respectively, while picture corresponding in such situations Rotation angle be set as 0 namely picture normally show without doing any rotation；

Situation 2: camera 300 is non-to be monitored multiple users for the first time while entering browsing pictures；It in such situations, can be right It copes with each user to be numbered, such as enters 3 people simultaneously, for example number is No. 31, No. 32, No. 33, it is clear if following Mode of looking at then saves each user respectively corresponding picture rotation angle, and if anti-peeping browse mode can then set each user Corresponding picture rotation angle is unified for 180 °, also i.e. by 180 ° of back of picture rotation to all users, thus prevent No. 31, No. 32, No. 33 users peep, or multiple user can not also be numbered, and directly control screen blank screen.In addition, right It is excessively repeated in normally entering situation (namely enter every time a new user) and not doing.

In the present embodiment, the user monitored for camera 300 exits that there is also a kind of special cases: camera 300 It monitors multiple users while exiting browsing pictures；Under such situation, if multiple user shares the same Customs Assigned Number, Directly the user information of multiple user is deleted, and updates the other users volume after Customs Assigned Number corresponding to multiple user Number.For example, the Customs Assigned Number that number is 2 is updated to 1, the user for being 3 by number if having the corresponding number of 3 users is 1 Number is updated to 2, subsequent and so on.And if multiple user respectively corresponds a Customs Assigned Number, directly by multiple use The user information at family is deleted, and updates the other users number after Customs Assigned Number corresponding to multiple user.Such as No. 31,33 Number user exits, then is updated to No. 31 for No. 32, and is updated to No. 32 for No. 34, is updated to No. 33 for No. 35, subsequent with such It pushes away.It is excessively repeated in addition, not doing for normally exiting situation (namely exit every time a new user).

In the present embodiment, by user list storage is numbered to user information, consequently facilitating the rotation to picture It is controlled.Under normal conditions, primary user just carries out picture browsing, therefore the rotation of picture under anti-peeping browse mode Angle change will not be too many, and then since the more more then corresponding picture rotation angles of user are also more under tracking-browsing mode, When therefore can facilitate multiple user's co-browses by numbering storage, the control to picture rotation is realized.For example, active user arranges When storing multiple users in table and being tracking-browsing mode, picture rotation control module 340 will be according to the use in user list Family information, and then realize the control to the rotation angle of each picture, to make each user that can obtain optimal vision Angle is appreciated, and then is improved the user experience.
