example 1

[0042] Figure 5 It is an implementation flow chart of Example 1 according to the embodiment of the present invention. In this example, the projector is set on a mobile terminal (also referred to as a portable terminal), and the distance sensing module 20 and the viewing module 30 acquire parameters at predetermined time intervals. , in the embodiment of the present invention, the projector can automatically adjust the display screen through such as Figure 5 The implementation of the process shown mainly includes the following steps:

[0043] Step 501, the user activates the projector function, and adjusts the distance between the portable terminal (that is, the projector) and the projection surface in the horizontal direction, so that the display screen of the projector can achieve better clarity and a suitable size;

[0044] Step 502 , start and initialize the automatic adjustment function, the central processing unit (that is, the processing module 40 ) obtains the distan...

example 2

[0052] Image 6 It is a flowchart of Example 2 according to the embodiment of the present invention, such as Image 6 As shown, the specific implementation of this example mainly includes the following steps:

[0053] Step 601, adjust the distance between the portable terminal and the projection surface in the horizontal direction, so that the display screen of the projector can achieve better clarity and appropriate size, obtain the reference distance, and store it in the central processing unit in the form of a digital signal for comparison in subsequent steps ;

[0054] Step 602, the central processing unit receives the distance and image information output by the distance sensing module 20 and the viewfinder module 30, and compares the distance and image information currently obtained with the distance and image information obtained last time to determine whether there is a change, and if there is a change, then Go to step 603;

[0055] Step 603, the central processing ...

Abstract

The invention discloses a projector and an adjusting method and mobile terminal for a display picture thereof, wherein the method comprises the following steps: acquiring the distance between the projector in the current position and a projecting plane, and acquiring an image of the surrounding environment of the projector; comparing the acquired distance with the reference distance and comparingthe acquired image with the reference image to acquire the position change of the projector, wherein the reference distance and the reference image correspond to the reference position of the projector; and the display picture of the projector is adjusted according to the position change to enable the adjusted display picture to be converted into the display picture when the projector is in the reference position. The invention can improve the applicable function of the projector and increase the user experience.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a projector, a method for adjusting a display screen thereof, and a mobile terminal. Background technique [0002] At present, when using the projector function to play a slide show, before playing, adjust the distance between the projector and the projection surface, the angle and horizontal position of the projector, etc., so that the display screen of the projector can achieve better clarity and a suitable size. [0003] However, during playback, the angle or position projected by the projector may be shifted due to the operator or other reasons, such as figure 1 As shown, the angle of the display screen is deflected or the display content is stretched and deformed, thereby affecting the viewing of the display content. In this case, only by manually readjusting the position and angle of the projector can the display picture of the projector be normal, which reduces the appl...
