Abstract

A projection method and an electronic device are provided. The method includes: projecting a first projection content from a first projection unit; determining at least one second projection unit of the electronic device in the presence of a first operation; and projecting the first projection content from the at least one second projection unit.

Claims

1. A projection method comprising:

projecting a first projection content from a first projection unit;

judging whether a second projection content is being projected by a second projection unit;

stopping projection of the second projection content from the second projection unit if the second projection content is being projected by the second projection unit;

stopping projection of the first projection content from the first projection unit; and

projecting a combined projection content from the second projection unit, wherein the combined projection content is a combination of the first projection content and the second projection content.

2. The method according to claim 1, further comprising:

generating an instruction for splitting a screen in response to a first operation; and

projecting the combined projection content from the second projection unit onto a plurality of projection regions in response to the instructions for splitting the screen.

3. The method according to claim 2, wherein the projecting of the combined projection content from the second projection unit onto the plurality of projection regions in response to the instruction for splitting the screen comprises:

acquiring a text part and a picture part of the first projection content;

projecting the text part of the first projection content from the second projection unit onto the plurality of projection regions; and

projecting the picture part of the first projection content from the second projection unit onto the plurality of projection regions.

4. The method according to claim 1, wherein if the first projection unit projects the first projection content onto a plurality of projection regions, the projecting of the first projection content from the second projection unit comprises:

generating an instruction for combining screens in response to a first operation; and

projecting the first projection content from the second projection unit onto a single projection region.

5. The method according to claim 4, wherein the projecting the first projection content from the second projection unit onto the single projection region comprises:

acquiring a text part and a picture part of the first projection content; and

projecting the text part and the picture part from the second projection unit onto the single projection region.

6. An electronic device comprising:

a processor; and

a plurality of projection units comprising a first projection unit and a second projection unit, wherein the first projection unit is operable to project a first projection content, and

wherein the processor is operable to judge whether a second projection content is being projected by the second projection unit,

stop projection of the second projection content from the second projection unit if the second projection content is being projected by the second projection unit,

stop projection of the first projection content from the first projection unit, and

project a combined projection content from the second projection unit, wherein the combined projection content is a combination of the first projection content and the second projection content.

7. The electronic device according to claim 6, wherein the processor is further operable:

to generate an instruction for splitting a screen in response to a first operation; and

to project the combined projection content from the second projection unit onto a plurality of projection regions in response to the instruction for splitting the screen.

8. The electronic device according to claim 7, wherein the processor is operable:

to acquire a text part and a picture part of the first projection content;

to project the text part of the first projection content from the second projection unit onto the plurality of projection regions; and

to project the picture part of the first projection content from the second projection unit onto the plurality of projection regions.

9. The electronic device according to claim 6, wherein if the first projection unit projects the first projection content onto a plurality of projection regions, the processor is operable:

to generate an instruction for combining screens in response to a first operation; and

to project the first projection content from the second projection unit onto a single projection region.

10. The electronic device according to claim 9, wherein the processor is operable:

to acquire a text part and a picture part of the first projection content; and

to project the text part and the picture part from the second projection unit onto the single projection region.
