S101. Acquire a first play content projected by the pico projector at a first moment of timer counting.

The first time when the timer is counted in this step is the time at which the start timer starts counting.

Acquiring the first play content projected by the pico projector at the first moment of the timer timing is to acquire the current moment of the pico projector at the time when the start timer starts counting Rong.

The trigger conditions for starting the timer timing include but are not limited to the following two situations:

The first case: the timer is started at the start of projection;

The second case: the timer is started after the preset time starts, wherein the preset time can be set according to actual needs.

S102. Acquire a second play content projected by the pico projector at a second time of the timer, wherein the first time and the second time are separated by a preset time threshold.

The second time that the timer is counted in this step is the time when the timer expires. The preset time threshold between the first time and the second time is the timer time.

Acquiring the second play content projected by the pico projector at the second moment of the timer timing is to obtain the play content of the current moment of the pico projector at the time of arrival of the timer.

S103. Control, according to the similarity between the first play content and the second play content, to control the pico projector to continue to project playback or turn off the pico projector.

It should be noted that when the timer is started again, the playing content of the current time may be acquired at the same time for similarity comparison with the playing content acquired at the time of arrival of the secondary time, or may not be acquired, but the last timing is adopted. The content of the content obtained at the time of arrival is compared with the content of the content obtained at the time of arrival of the timed time. Of course, other rules for obtaining the content to be played may be set according to actual needs. The rules are not limited.

In the embodiment of the present invention, the manner of comparing whether the content is played before and after is similar, including but not limited to the following two modes:

Step 1. The play data corresponding to the first play content and the second play content is stored in the buffer area.

Step 2: Acquire first play data corresponding to the first play content stored in the buffer area and corresponding second play data of the second play content.

Step 3: Comparing the similarity between the first play data and the second play data, and controlling the pico projector to continue to project playback or turn off the pico projector according to the similarity comparison result.

The second way includes:

Step 1. Capture and store a play screen corresponding to the first play content and the second play content.

Step 2: Acquire a first play screen corresponding to the first play content and a second play screen corresponding to the second play content.

Step 3: Comparing the similarity between the first play screen and the second play screen, and controlling the pico projector to continue to project playback or turn off the pico projector according to the similarity comparison result.

In addition, for the pico projector, the playback data corresponding to the playback content is stored at the same time as the projection and playback, and therefore, the stored playback data at the corresponding time can be directly obtained for comparison.

In order to further understand the energy-saving method of the micro-projector optical machine provided by the embodiment of the present invention, the following is a specific example. As shown in FIG. 2, it is a schematic flowchart of the example, and the example specifically includes:

Step S201, starting the projection start time or starting a period of time after the projection starts;

Step S202: Acquire and store the currently played first played content at the time of starting the timer;

Step S203: Acquire and store the currently projected second play content when the timer timing time reaches the time;

Step S204: Comparing the similarity between the stored first play content and the second play content, determining whether the similarity is less than a similarity threshold, and if not, restarting the timer;

Step S205: If the similarity is greater than or equal to the similarity preset threshold, a pop-up prompt box prompts the user whether to continue the projection play;

Step S206, determining whether the user selects according to the prompt box within a certain period of time, if not, the micro projector optome is turned off, and the projection is ended;

In step S207, if a selection is made, it is determined whether the selection is to continue the projection playback, and if so, the timer is restarted, and if not, the pico projector is turned off, and the projection is ended.
