Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
The embodiment of the present invention provides a kind of projecting method, be applied to projection arrangement, this projection arrangement can be smart mobile phone, panel computer, super, projecting apparatus, the terminal such as multimedia player, run just like operating systems such as Android, Windows, Linux in projection arrangement.
Fig. 1 is the schematic flow sheet of the projecting method in the embodiment of the present invention, and shown in figure 1, the method comprises:
S101: the selection according to user operates, and the display interface shown by the display unit of projection arrangement determines region to be projected, wherein, the area in region to be projected is less than or equal to the area of display unit;
S102: the displaying contents that the optical projection unit controlling projection arrangement projects in region to be projected.
In specific implementation process, S101 is specifically as follows: receive and select operation, wherein, selects operation for determining an enclosed region on display interface; Be received in the determination operation in enclosed region, enclosed region is defined as region to be projected.
Specifically, the desk interface shown by the display unit of projection arrangement can comprise the icon of multiple application, as shown in Figure 2, now, user opens at least one application, such as opens application 1, so, the window of application 1 is just comprised in the display interface shown by display unit.Projection arrangement receives user and uses as finger, the operating bodies such as pointer slide on the display unit, namely selection operation is carried out, select the sliding trace of operation can surround an enclosed region, on display interface, namely determine an enclosed region, the area of this enclosed region is less than or equal to the area of display interface, next, user carries out determination operation in this enclosed region, as user double-clicks display unit in enclosed region, or length presses display unit, projection arrangement is after receiving determination operation, current enclosed region is defined as region to be projected, as shown in Figure 3.
Certainly, selection operation can also for growing by display unit, multi-point touch display unit or carrying out prearranged gesture on the display unit, now, after projection arrangement receives this selection operation, control display unit and show deformable rectangle frame, user can adjust the size of rectangle frame by the corner dragging this rectangle frame, shape, also rectangle frame can be dragged to adjust its position, until adjusted to suitable, then, projection arrangement receives the determination operation of user, and current enclosed region is defined as region to be projected.
In actual applications, select operation and determination operation to be other forms of operation, the present invention is not specifically limited.
Further, in specific implementation process, S102 is specifically as follows: control display unit display projection window, and receive the drag operation of towing displaying contents; When displaying contents tows in projection window by drag operation, control both optical projection unit projects displaying contents.
Specifically, after region to be projected determined by projection arrangement, control display unit and show a projection window, as shown in Figure 4, when user sees this projection window, can tow in this projection window by the displaying contents in the region to be projected determined in S101, next, the displaying contents in region to be projected projects away by the optical projection unit that projection arrangement just can control self.
Further, the resolution supported due to display unit and optical projection unit is different, institute is so before projection, need to adjust displaying contents, carry out the resolution that matching optics projecting cell is supported, so, the step of above-mentioned control both optical projection unit projects displaying contents, specifically can comprise: the resolution supported based on optical projection unit, convergent-divergent process is carried out to displaying contents; Displaying contents after control both optical projection unit projects convergent-divergent.
Specifically, projection arrangement is before the displaying contents in projection region to be projected, to displaying contents by such as most neighbor interpolation, bilinear interpolation value, cubic convolution scheduling algorithm carry out image scaling, make the displaying contents after convergent-divergent can the picture pixel supported of matching optics projecting cell, finally, the displaying contents after convergent-divergent projects away by control both optical projection module.
Such as, the resolution of display unit is 1280 × 720, and the resolution that optical projection unit supports is 800 × 600.If region to be projected the resolution of displaying contents be 400 × 300, then need all to amplify twice to the horizontal and vertical of displaying contents, after the conversion of convergent-divergent algorithm, just obtain the image of 800 × 600 resolution.
For another example, if region to be projected the resolution of displaying contents be 1000 × 500, in order to reach the image pixel within 800 × 600, then need all to reduce 1.25 times to the horizontal and vertical of displaying contents, now, after the conversion of convergent-divergent algorithm, displaying contents after reducing is the picture of 800 × 400 pixels, the resolution supported due to optical projection unit is 800 × 600, so, the transverse direction of displaying contents can not fill up view picture projected image, so, for this problem, ater can be arranged in the region do not filled up.
In another embodiment, in order to not affect the operation of user to display unit, after the displaying contents after projection arrangement control both optical projection unit projects convergent-divergent, display unit can be controlled and hide projection window, now, display unit shows the window of application 1, as shown in Figure 5.
It should be noted that, projecting method described in one or more embodiment above-mentioned is just for the handling process of a two field picture, applicable equally for multiple image, like this, if the displaying contents in region to be projected changes, along with the change of the displaying contents in region to be projected changes during the image that optical projection unit projects.
From the above, user can be selected all or part of region by projection arrangement on display interface, and namely the displaying contents in region to be projected projects away, improves the flexibility of projection pattern, and the projection enriching user is experienced
Based on same inventive concept, the embodiment of the present invention provides a kind of projection arrangement, and this projection arrangement is consistent with the projection arrangement described in one or more embodiment above-mentioned.
Fig. 6 is the structural representation of the projection arrangement in the embodiment of the present invention, and shown in figure 6, this projection arrangement comprises: display unit 61, optical projection unit 62 and control unit 64; Wherein, control unit 63, operates for the selection according to user, the display interface shown by the display unit of projection arrangement determines region to be projected, and wherein, the area in region to be projected is less than or equal to the area of display unit; The displaying contents that the optical projection unit controlling projection arrangement projects in region to be projected.
