Correspondingly, including display in the intermediate display parameters that intelligent terminal is calculated according to the first display pattern and the second display pattern Angle difference, display size difference and display distance difference.It is illustrated below using an illustrative examples.
Fig. 3 A is please referred to, it illustrates the flow chart for the mode switching method that another embodiment of the present invention provides, this realities Applying example, switching method is used to for smart phone be illustrated in this mode, this method comprises:
Step 301, it detects whether to receive mode switching signal, mode switching signal is used to indicate video display area The second display pattern is switched to from the first display pattern being presently in.
When being equipped with gravity sensor in intelligent terminal, and opening gravity sensing function, user can be by changing intelligence Can the rotation angle of terminal the display pattern of video display area is switched over (for example intelligent terminal is rotated to be into cross by vertical screen Screen)；It can also include that pattern switching component (for example full frame control and cancels full frame control in video display area in application program Part), when the user clicks when the pattern switching component, the display pattern of video display area can be switched over.As one kind Possible embodiment, as shown in Figure 3B, this step may include the possible embodiment of the following two kinds.
In a kind of possible embodiment, step 301A obtains the rotation angle of screen by gravity sensor；When this When rotating angle greater than predetermined angle threshold value, determination receives mode switching signal.
When playing video in application program, intelligent terminal is the rotation for passing through built-in gravity sensor and obtaining terminal screen Gyration.In order to avoid maloperation, when detecting that the rotation angle is greater than predetermined angle threshold value, intelligent terminal determination is received Mode switching signal, when the rotation angle is less than predetermined angle threshold value, intelligent terminal, which determines, does not receive mode switching signal (screen Curtain rotation is as caused by user's normal operating).
For example, predetermined angle threshold value can be 55 °, i.e., when rotating angle greater than 55 °, just determination receives intelligent terminal Mode switching signal.
In alternatively possible embodiment, step 301B detects whether to receive to mode in video display area The operation signal of changeover module；When receiving the operation signal to pattern switching component, determination receives mode switching signal.
It may include that pattern switching component (for example full frame control and cancels full frame control in video display area in application program Part), intelligent terminal is the operation signal for passing through the pattern switching component and receiving user's triggering.When receiving to the pattern switching group When the operation signal of part, intelligent terminal determination receives mode switching signal.
It should be noted that intelligent terminal can also be by other possible embodiment reception pattern switching signals, this Implementation is defined not to this.
Step 302, it is shown according to corresponding first display parameters of the first display pattern and the second display pattern corresponding second Show that parameter calculates display parameters difference.
Due to display size of the video display area under different display modes and display position difference, difference display Under mode, the corresponding display parameters of video display area are also different.When receiving mode switching signal, smart machine is obtained It is presently in corresponding first display parameters of the first display pattern and (after switch mode) second display pattern corresponding second Display parameters, and display parameters difference is calculated according to the first display parameters and the second display parameters.
In order to determine unique display position of the video display area in on-screen display (osd) area, the first display parameters and second At least need to include angles of display, display size and reference point coordinate in display parameters, correspondingly, according to the first display parameters and The display parameters difference that second display parameters are calculated includes angles of display difference (being calculated according to angles of display), display Dimension difference (being calculated according to display size) and display distance difference (being calculated according to reference point coordinate).
Based on Fig. 3 A, as shown in Figure 3 C, in a kind of possible embodiment, this step be may include steps of.
Step 302A, obtaining includes the first angles of display in the first display parameters, and the first angles of display is used to indicate first Angle under display pattern between video display area and on-screen display (osd) area.
It includes the first angles of display that intelligent terminal, which obtains in the first display parameters, which is current video Angle between display area and on-screen display (osd) area.For example, the first display pattern being presently in is normal displaying mode, depending on Angle between frequency display area and on-screen display (osd) area is 0 °；The first display pattern being presently in is that left transverse screen is full frame aobvious Show mode, the angle between video display area and on-screen display (osd) area is 90 °
It should be noted that the present embodiment, using normal displaying mode as reference model, video display area and screen are shown Angle between region is calculated on the basis of the reference model.In other possible embodiments, video viewing area Angle between domain and on-screen display (osd) area can also be obtained according to other benchmarks, and the present embodiment is limited not to this It is fixed.
Step 302B, obtaining includes the second angles of display in the second display parameters, and the second angles of display is used to indicate second Angle under display pattern between video display area and on-screen display (osd) area.
Similar with above-mentioned steps 302A, intelligent terminal calculates under the second display pattern, and video display area and screen are aobvious Show the angle (i.e. the second angles of display) between region.For example, when the second display pattern is vertical screen screen mode toggle, the second display Angle is 0 °, and when the second display pattern is right full-screen display mode, the second angles of display is -90 °.
Step 302C calculates angles of display difference according to the first angles of display and the second angles of display.
Wherein, angles of display difference=second the-the first angles of display of angles of display.
For example, when pattern switching instruction indicates the normal displaying mode by being presently in (corresponding first angles of display is 0 °) When being switched to left transverse screen display mode (corresponding second angles of display is 90 °), which is 90 ° -0 °=90 °, That is the video display area under the second display pattern can be by revolving the video display area under the first display pattern clockwise It is obtained after turning 90 °.
Angles of display difference is determined as display parameters difference by step 302D.
The angles of display difference being calculated is determined as display parameters difference by intelligent terminal.
Step 302E, obtains the first display size for including in the first display parameters, and the first display size is used to indicate the The width and height of video display area under one display pattern.
(or normal display mould is switched to by full-screen display mode when being switched to full-screen display mode by normal displaying mode Formula) when, the size of video display area can change, and therefore, after receiving pattern switching instruction, intelligent terminal obtains the The first display size for including in corresponding first display parameters of one display pattern.
For example, the first display pattern being presently in is normal displaying mode shown in figure 1A, intelligent terminal gets view The width 111 and height 112 of frequency display area 11, wherein the width of video display area is 720px, video display area Height is 300px.
Step 302F, obtains the second display size for including in the second display parameters, and the second display size is used to indicate the The width and height of video display area under two display patterns.
Similar with above-mentioned steps 302E, intelligent terminal, which obtains in corresponding second display parameters of the second display pattern, includes Second display size.
For example, when the second display pattern be Figure 1B (c) shown in left transverse screen full-screen display mode when, intelligent terminal is got The width of video display area is the height of on-screen display (osd) area, and the height of video display area is on-screen display (osd) area Width, wherein the width of video display area is 1280px, and the height of video display area is 720px.
Step 302G calculates display size difference, display size difference according to the first display size and the second display size Including width differential and height difference.
Wherein, display size difference=second the-the first display size of display size.
For example, in conjunction with above-mentioned steps 302E and step 302F the embodiment described, when video display area is by normally showing When pattern switching is left transverse screen full-screen display mode, the width differential=1280-720=560px for including in display size difference, Height difference=720-300=420px.
Display size difference is determined as display parameters difference by step 302H.
The display size difference being calculated is determined as display parameters difference by intelligent terminal.
Step 302I, obtains the first reference point coordinate for including in the first display parameters, and the first reference point coordinate is first Coordinate of the predetermined reference point in on-screen display (osd) area in video display area under display pattern.
In mode handover procedure, video display area can carry out rotation and scaling with center point, in order to make to revolve Video display area after turning scaling can adapt to on-screen display (osd) area, and (i.e. on-screen display (osd) area can include rotation scaling completely Video display area afterwards), intelligent terminal obtains under the first display pattern and the second display pattern, makes a reservation in video display area Display distance difference between reference point, and the display that rotation scales rear video display area is adjusted according to the display distance difference Position.
After receiving pattern switching instruction, intelligent terminal, which obtains in corresponding first display parameters of the first display pattern, includes The first reference point coordinate.Wherein, the first reference point coordinate can be the coordinate or central point on vertex in video display area Coordinate.
For example, the first display pattern is normal displaying mode, and the first reference point coordinate is video display area central point Coordinate, intelligent terminal get the first reference point coordinate be (600px, 360px).
Step 302J, obtains the second reference point coordinate for including in the second display parameters, and the second reference point coordinate is second Coordinate of the predetermined reference point in on-screen display (osd) area in video display area under display pattern.
Similar with above-mentioned steps 302I, smart machine, which obtains in corresponding second display parameters of the second display pattern, includes Second reference point coordinate.
For example, the second display pattern is left transverse screen full-screen display mode (screen resolution 1280*720), and second joins Examination point coordinate be video display area central point coordinate, intelligent terminal get the second reference point coordinate be (640px, 360px)。
Step 302K calculates display distance difference, display distance according to the first reference point coordinate and the second reference point coordinate Difference is used to indicate distance of the predetermined reference point in on-screen display (osd) area under the first display pattern and the second display pattern.
Intelligent terminal calculates display distance difference, meter according to the first reference point coordinate got and the second reference point coordinate Calculation obtains under first mode and second mode, distance (i.e. display distance difference) between video display area central point.
For example, in conjunction with above-mentioned steps 302E and step 302F the embodiment described, when the first reference point coordinate is (600px, 360px) and the second reference point coordinate is (640px, 360px), and display distance difference is [(640-600)2+(360-360)2]0.5 =40.
Display distance difference is determined as display parameters difference by step 302L.
The display distance difference being calculated is determined as display parameters difference by intelligent terminal.
It should be noted that in order to save the process resource of intelligent terminal, when the angles of display difference being calculated is (instruction switches between vertical screen full-screen display mode and the full-screen display mode of falling vertical screen, or in left transverse screen when 180 ° (or -180 °) Switch between full-screen display mode and right transverse screen full-screen display mode), since video display area is under full-screen display mode On-screen display (osd) area, it is 0 that intelligent terminal, which directly determines display size difference, and display distance difference is 0, to eliminate acquisition The process of first display size, the second display size, the first reference point coordinate and the second reference point coordinate.
Step 303, at least one set of intermediate display parameters are calculated according to the first display parameters and display parameters difference.
By above-mentioned steps 302A to step 302L, intelligent terminal obtains including angles of display difference, display size difference With the display parameters numerical value of display distance difference.
After display parameters difference is calculated, intelligent terminal further according to current display mode and display parameters difference, It is aobvious that calculating at least one set is used to indicate video display area real-time display position and the centre of display size in mode handover procedure Show parameter.
As a kind of possible embodiment, this step may include steps of.
Step 303A, obtains adjustment factor, and adjustment factor is used for the change of video display area during control mode switch Change degree, 0 < adjustment factor < 1.
