detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings.

The embodiment of the invention provides a projection method, which is applied to a projection device, and the projection device can be a terminal such as a smart phone, a tablet computer, a superbook, a projector, a multimedia player, etc., and the projection device runs operations such as Android, Windows, and Linux. system.

1 is a schematic flowchart of a projection method according to an embodiment of the present invention. Referring to FIG. 1, the method includes:

S101: determining, according to a user's selection operation, an area to be projected on a display interface displayed by the display unit of the projection device, wherein an area of the area to be projected is less than or equal to an area of the display unit;

S102: Control an optical projection unit of the projection device to project display content in the area to be projected.

In a specific implementation process, S101 may specifically be: receiving a selection operation, wherein the selecting operation is for determining a closed area on the display interface; receiving the determining operation in the closed area, and determining the closed area as the area to be projected.

Specifically, the desktop interface displayed by the display unit of the projection device may include icons of multiple applications, as shown in FIG. 2, at this time, when the user opens at least one application, such as opening the application 1, the display unit displays The window of application 1 is included in the display interface. The projection device receives the user's sliding operation on the display unit by using an operating body such as a finger or a stylus pen, that is, performs a selection operation, and the sliding track of the selection operation can enclose a closed area, that is, a closed area is determined on the display interface. The area of the closed area is less than or equal to the area of the display interface. Next, the user performs a determining operation in the closed area, such as the user double-clicking the display unit in the closed area. Or long press the display unit, after receiving the determining operation, the projection device determines the current closed area as the area to be projected, as shown in FIG.

Certainly, the selecting operation may further perform a predetermined gesture for the long press display unit, the multi-touch display unit, or the display unit. At this time, after receiving the selection operation, the display device controls the display unit to display the deformable rectangular frame, and the user You can adjust the size and shape of the rectangle by dragging the corners of the rectangle. You can also drag the rectangle to adjust its position until it is adjusted to suitability. Then, the projector receives the user's OK operation and will present the current The closed area is determined as the area to be projected.

In an actual application, the selection operation and the determination operation may also be other forms of operations, which are not specifically limited in the embodiment of the present invention.

In actual implementation, in a specific implementation process, S102 may specifically be: controlling the display unit to display a projection window, and receiving a drag operation for dragging the display content; when the drag operation drags the display content into the projection window, controlling the optical projection unit to display the projection content.

Specifically, after the projection device determines the area to be projected, the control display unit displays a projection window. As shown in FIG. 4, when the user sees the projection window, the display content of the area to be projected determined in S101 can be dragged to the Within the projection window, next, the projection device can control its own optical projection unit to project the display content of the area to be projected.

In practical applications, since the display unit and the optical projection unit support different resolutions, before the projection, the display content needs to be adjusted to match the resolution supported by the optical projection unit, then the above-mentioned control optical projection unit is projected and displayed. The step of content may specifically include: performing scaling processing on the display content based on a resolution supported by the optical projection unit; and controlling the optical projection unit to project the scaled display content.

Specifically, before the projection device projects the display content of the area to be projected, the image is scaled by an algorithm such as nearest neighbor interpolation, bilinear interpolation, and cubic convolution, so that the scaled display content can match the optical projection. The pixels supported by the unit, and finally, the control The optical projection module projects the scaled display.

For example, the resolution of the display unit is 1280×720, and the resolution supported by the optical projection unit is 800×600. If the resolution of the display content of the area to be projected is 400×300, it is necessary to double the horizontal and vertical directions of the display content, and after the conversion by the scaling algorithm, the image of 800×600 resolution is just obtained.

For example, if the resolution of the display content of the area to be projected is 1000×500, in order to achieve image pixels within 800×600, the horizontal and vertical directions of the display content need to be reduced by 1.25 times. At this time, the scaling algorithm is converted. After that, the reduced display content is a picture of 800×400 pixels. Since the resolution supported by the optical projection unit is 800×600, then the horizontal direction of the display content cannot fill the entire projected image, then, for this problem, Set the unfilled area to pure black.

In another embodiment, in order not to affect the operation of the display unit by the user, after the projection device controls the optical projection unit to project the scaled display content, the display unit may be controlled to hide the projection window. At this time, the application 1 is displayed on the display unit. The window is shown in Figure 5.

It should be noted that the projection method described in one or more embodiments described above is only for the processing flow of one frame of image, and is also applicable to multi-frame images, so that if the display content in the area to be projected changes, the optical projection unit projects. The image changes as the display content in the area to be projected changes.

It can be seen from the above that the projection device can project all or part of the area selected by the user on the display interface, that is, the display content of the area to be projected, thereby improving the flexibility of the projection mode and enriching the projection experience of the user.

Based on the same inventive concept, an embodiment of the present invention provides a projection apparatus that is consistent with the projection apparatus described in one or more of the above embodiments.
