The technical solutions of the present invention are described in detail with reference to the drawings and the specific embodiments, and it should be understood that the embodiments and the specific technical features in the embodiments of the present invention are merely illustrative of the technical solutions of the present invention, and are not restrictive, and the embodiments and the specific technical features in the embodiments of the present invention may be combined with each other without conflict.

Fig. 1 is a schematic structural diagram of an electronic device in an embodiment of the present invention, where the electronic device includes:

a first body 101;

the second body 102 is connected with the first body 101 through a first connecting piece 103, and the relative position relationship between the first body 101 and the second body 102 can be changed through the first connecting piece 103;

a first display module 104 disposed on a first surface of the second body 102 for displaying a first image on the first surface;

the second display module 105 is disposed on the second body 102 and configured to enable a second surface of the electronic device to display a second image;

the detection module (not shown in the figure) is used for collecting the characteristic parameters of the electronic equipment and judging whether the characteristic parameters meet the conditions;

and a processing module (not shown) for controlling the display of the second image according to the determination result.

First, in the embodiment of the present invention, the electronic device may be a notebook computer, the first body 101 may be a host side of the notebook computer, that is, a main body provided with a keyboard and a touch panel, the second body 102 may be a display side of the notebook computer, and a display screen is disposed on the display side. The display surface of the display screen is used as the first surface of the second body 102, that is, the first display module 104 is the display screen on the second body 102.

The second display module 105 is disposed on the second body 102, and of course, the second display module 105 may be a projection module, and the projection module may project an image on the electronic device onto a surface outside the electronic device. The second display module 105 may be disposed on a first edge of the second body 102, where the first edge may be an edge far from the first body 101.

Specifically, the second display module 105 may be disposed at a first edge of the display side of the notebook computer, and the first edge is an edge of the display side not connected to the host side edge, such as the first edge shown in fig. 2, and the first edge may be an edge far from the first body 101, or the first edge is an edge parallel to the first connector 103 and far from the first body 101.

Of course, in the embodiment of the present invention, the second display module may also be disposed on an outer surface of the second body 102, where the outer surface is a non-first surface on the second body 102, that is: the first side is opposite to the display side, such as shown in fig. 2.

Further, in the embodiment of the present invention, the second display module 105 has a specific orientation besides the set position. The display direction of the second display module 105 is the first side of the second main body 102, wherein the second main body 102 is taken as a dividing plane, the side where the first main body 101 does not exist is taken as the first side, and the side where the first main body 101 exists is taken as the second side.

For example, as shown in fig. 2, the second display module 105 is oriented away from the display side of the notebook computer, that is, the display direction of the display screen of the notebook computer is oriented towards the user, and the projection direction of the second display module 105 is oriented away from the user.

The electronic device with the functional module further comprises a detection module (not shown in the figure), wherein the detection module is used for collecting the characteristic parameters of the electronic device and judging whether the characteristic parameters meet the conditions. That is, the detection module can detect a current state of the electronic device in real time, and if the state of the electronic device is detected to be changed. The detection module collects and judges whether the changed characteristic parameters meet the conditions.

The implementation of the technical solution of the present invention is described in different cases by different characteristic parameters.

The first condition is as follows:

first, the detecting module in the electronic device detects the rotation angle of the first connecting element 103. In the embodiment of the present invention, the direct reason for the rotation of the first connecting element 103 is that the first body 101 and the second body 102 are separated or closed, and the second body 102 rotates around the first body 101, so the detecting module can detect the rotation angle of the first connecting element 103 in real time.

After the detecting module detects the rotation angle of the first connecting element 103, the detecting module sends the rotation angle to a processing module (not shown), and the processing module determines whether the rotation angle detected by the detecting module is greater than or equal to a predetermined threshold. If the processing module determines that the rotation angle is greater than or equal to the preset threshold, the electronic device will determine that the electronic device is in a normal use state, for example, it detects that the rotation angle of the first connection element 103 is equal to 90 degrees, which indicates that the electronic device is in a use state, the electronic device will continue to detect the first state parameter of the first connection element 103, where the first state parameter may also be the rotation angle of the first connection element 103, after detecting the rotation angle of the first connection element 103, the processing module will determine whether the first state parameter of the first connection element meets a predetermined condition, and if the first state parameter meets the predetermined condition, the processing module will control the display of the second image of the second display module 105.

For example, after the rotation angle of the first connecting element 103 reaches 90 degrees, it is described that the notebook computer is in a normal use state, if the second display module 105 projects the second image, the second image can be projected onto the wall surface, and at this time, the second body 102 will not block the second image, and other users can also view the second image. In this case, the detecting module in the notebook computer will continue to detect the rotation angle of the first connecting element 103, if the first connecting element 103 continues to rotate, the second image will be projected onto the ground or the supporting surface of the notebook computer, and if the rotation angle of the first connecting element 103 is greater than a preset threshold, the processing module in the notebook computer will control the display of the second image, for example, rotate the second image, or adjust the size of the second image, or adjust the projection direction of the second image. Therefore, the second image can be automatically adjusted according to different projection conditions, and the user can clearly watch the second image.

Further, in the embodiment of the present invention, the first state parameter may include a rotation angle of the first connector 103, and may further include an orientation of the second display module 105, where the orientation of the second display module 105 determines a plane on which the second image is located, for example, when the orientation of the second display module 105 is opposite to the display direction of the first plane, the second image will be projected onto a wall surface, and when an included angle formed by the orientation of the second display module 105 and the display direction of the first plane is an obtuse angle, the second image will be projected onto a supporting surface supporting the electronic device or a ground surface. After determining the orientation of the second display module 105, the processing module in the electronic device determines a deviation value between the orientation of the second display module 105 and a predetermined orientation, where the predetermined orientation may be an orientation opposite to the display direction of the first surface, and if the deviation value between the orientation of the second display module 105 and the predetermined orientation is greater than or equal to a predetermined threshold value, that is, the orientation of the projection module is already greatly deviated from the original projection orientation, the processing module controls the display of the second image.

Of course, in the embodiment of the present invention, the rotation angle may be combined with the orientation of the second display module 105, for example, after the rotation angle of the first connection element 103 is determined, the electronic device determines whether the rotation angle is greater than or equal to a preset threshold, and then detects the orientation of the second display module 105 when the rotation angle is greater than or equal to the preset threshold, and when a deviation value between the orientation of the second display module 105 and the preset orientation is greater than or equal to the preset threshold, a processing module in the electronic device controls the display of the second image.

Case two:

the detecting module in the electronic device can detect a second state parameter of a second connecting member, where the second connecting member is used to connect the second body 102 and the second display module 105, and a relative position relationship between the second display module 105 and the second body 102 can be changed through the second connecting member. When the relative position relationship between the second display module 105 and the second body 102 changes, the second connection element needs to rotate, so that the second state parameter can represent the rotation angle of the second connection element.

It should be noted here that, because the second display module 105 is a projection module, the projection position of the projection module can be realized by adjusting the second connecting member, for example, the second display module 105 can be adjusted by the second connecting member, so that the second display module 105 can project the second image onto the wall surface or onto the supporting surface. In brief, the second connecting member can change the projection direction of the second display module 105 to rotate upward and downward in the vertical direction, so that the second image can be moved from the wall surface to the supporting surface, where the supporting surface is the surface for supporting the electronic device.

After the detection module detects the second state parameter of the second connecting piece, the detection module sends the second state parameter to the processing module, and the processing module judges whether the second state parameter detected by the detection module meets a second preset condition, namely simply whether the rotation angle of the second connecting piece is larger than or equal to a preset threshold value. If the processing module determines that the rotation angle is greater than or equal to the predetermined threshold, the processing module controls the second display module 105 to display the second image.

For example, when the detection module detects that the rotation angle of the second connecting member is greater than or equal to the preset threshold, it indicates that the second image projected by the second display module 105 moves from being displayed on the wall surface to being displayed on the supporting surface, and at this time, the electronic device adjusts the display of the second image, where the adjustment may be rotation of the second image, or adding enlargement or reduction processing to the second image during rotation.

Further, in the embodiment of the present invention, the second state parameter may include, in addition to the rotation angle of the second connecting member, an orientation of the second display module 105, where the orientation represents an orientation adjustment of the second display module 105 in another dimension.

For example, in the above description, the adjustment of the orientation of the second display module 105 in the vertical direction is explained, and the orientation here is the adjustment of the orientation of the second display module 105 in the horizontal direction. After determining the orientation of the second display module 105, the processing module in the electronic device determines a deviation value between the orientation of the second display module 105 and the predetermined orientation, and if the deviation value is greater than or equal to a preset threshold value, that is, if the orientation of the projection module deviates from the original projection orientation to a large extent, the processing module controls the display of the second image.

Of course, in the embodiment of the present invention, the rotation angle may be combined with the orientation of the second display module 105, for example, after the rotation angle of the second connector is determined, the electronic device determines whether the rotation angle is greater than or equal to a preset threshold, and then detects the orientation of the second display module 105, and when a deviation value between the orientation of the second display module 105 and a predetermined orientation is greater than or equal to the preset threshold, a processing module in the electronic device controls the display of the second image. Therefore, the state parameters of the second display module can be detected in multiple dimensions, so that the electronic equipment can accurately realize automatic adjustment on the second image, and the display effect of the second image on the second surface is improved.

Case three:

in this case, the detecting module may first detect a first state parameter of the first connecting element 103, where the first state parameter may represent the rotation angle of the first connecting element 103. And under the condition that the first state parameter meets the preset condition, the detection module in the electronic equipment detects the second state parameter of the second connecting piece, and when the second state parameter meets the second preset condition, the electronic equipment controls the display of the second image.

Specifically, the electronic device is a notebook computer, the second display module 105 is a projection module, and the projection module is disposed at an edge of a display surface of the notebook computer (as shown in fig. 2), so that if the notebook computer is in a closed state, the notebook computer is in a dormant state, and there is no need to adjust a projection image of the projection module. Therefore, in the embodiment of the present invention, the detecting module first detects the rotation angle of the first connecting element 103, when the rotation angle of the first connecting element 103 is greater than or equal to the predetermined threshold, it indicates that the notebook computer is in a used state, and the detecting module detects the second connecting element, that is, detects the rotation angle of the second connecting element, and if the rotation angle of the second connecting element is greater than or equal to the predetermined threshold, the processing module in the electronic device controls the display of the second image.

For example, if the notebook computer first detects that the rotation angle of the first connecting element 103 exceeds 90 degrees, that is, the included angle between the display side and the host side of the notebook computer reaches 90 degrees, the notebook computer will start detecting the second connecting element, and if the notebook computer also detects that the second connecting element rotates, and the rotation angle is greater than 30 degrees, it indicates that the plane where the second image is located is changed, that is: the display of the second image is moved from the wall surface to the support surface. The notebook computer adjusts the display of the second image based on the detected rotation angle of the second connector. The adjustment here may be rotation of the second image, and enlargement or reduction of the second image based on the rotation of the second image.

In the second case, the detection of the rotation of the second display module 105 in multiple dimensions is also described, and the second state parameter herein may include the detection of the rotation of the second display module 105 in multiple dimensions. I.e. including rotation detection in the vertical direction and rotation detection in the horizontal direction, will not be described in detail here.

In the above three cases, it is described that when the characteristic parameter detected by the detection module satisfies a predetermined condition, that is, the rotation angle of the first connecting element is greater than or equal to a preset threshold, or the rotation angle of the second connecting element is greater than or equal to a preset threshold, or the rotation angles of both the first connecting element and the second connecting element are greater than or equal to a preset threshold, or the orientation of the second display module satisfies the predetermined condition, the processing module in the electronic device controls the display of the second image.

In an embodiment of the present invention, the control of the second image by the processing module may be: a predetermined rotation parameter is determined such that the second image is rotated on the second surface according to the predetermined rotation parameter.

It should be noted that the second image is rotated on the second surface, that is, the second image is rotated on the imaging surface, for example, when the second image is moved from the wall surface to the supporting surface for displaying, the second image is rotated on the supporting surface, not rotated with respect to the wall surface. The second surface is referred to herein as the imaging surface of the second image.

For example, when the rotation angle of the first connection element 103 on the electronic device is greater than or equal to 90 degrees, the processing module determines a rotation parameter, and the rotation parameter determines the rotation angle of the second image, if the rotation angle of the first connection element 103 is exactly 160 degrees, it indicates that the second image is adjusted to be displayed on the supporting surface by being displayed on the wall surface, and at this time, the rotation parameter determined by the processing module is 90 degrees, and the processing module in the electronic device controls the second display module 105 to rotate the second image on the supporting surface by 90 degrees, where the rotation may be clockwise rotation or counterclockwise rotation, and the rotation direction of the second image may be determined according to different application scenarios.

Further, in the embodiment of the present invention, the rotation of the second image may be performed in the following two ways.

The first method is as follows:

the electronic device further includes a storage module, which is used to store the corresponding relationship between the state parameter and the rotation parameter, for example, when the first connecting element 103 rotates 120 degrees, the corresponding rotation parameter is 90 degrees, and when the first connecting element rotates 160 degrees, the corresponding rotation parameter is 120 degrees. Of course, this is only an example and is not a limitation to the corresponding relationship, and the corresponding relationship may be customized according to a specific application scenario.

After determining that the characteristic parameter of the electronic device meets the predetermined condition, the processing module determines a first state parameter of the first connector 103, that is, a rotation angle of the first connector 103, the processing module retrieves a rotation parameter corresponding to the rotation angle from the storage module according to the rotation angle of the first connector, then the processing module rotates the second image according to the determined rotation parameter, then the processing module obtains a third image obtained by rotating the second image, and sends the third image to the second display module 105, and then the second display module 105 displays the third image on the second surface, that is, the second image rotates on the second surface, and finally displays the third image.

In the embodiment of the present invention, in addition to the rotation of the second image on the second surface by the processing module, the rotation of the second image on the second surface can be realized by a rotating element (not shown in the figure) in the electronic device, that is, the rotating element rotates the second display module according to the rotation parameter sent by the processing module, so that the second image is rotated on the second surface.

Specifically, in the embodiment of the present invention, the electronic device further includes a rotating element, which may be the second connecting element described above, or another connecting element different from the second connecting element, and the rotating element is connected to the processing module, and after the processing module determines the rotation parameter, the processing module controls the rotating element to adjust the projection mode of the second display module 105 according to the determined rotation parameter, for example, rotate the second display module 105, so as to rotate the second image on the second surface.

That is, the rotating member can control the rotation of the whole second display module 105, so that the second image projected by the second display module 105 can also rotate, and the second image can rotate on the second surface.

Here, the rotation parameter of the processing module may be determined according to the rotation angle of the first connector 103, for example, when the rotation angle of the first connector 103 is 120 degrees, the rotation parameter may be 90 degrees, that is, when the second image is rotated by 90 degrees, or when the rotation angle of the first connector 103 is 180 degrees, the rotation parameter may be that the second image is rotated by 180 degrees. Of course, this is only an example, and the corresponding relationship between the angles may be adjusted according to a specific application scenario.

Of course, in practical applications, the user may also manually operate the rotating member to rotate the second image projected on the second surface by the second display module 105.

The following further describes an embodiment of the present invention in an application scenario.

The electronic equipment is a notebook computer, a projection module is arranged above a display panel of the notebook computer, the projection module can project a first image displayed on the notebook computer onto a projection surface, and the projection surface can be a wall surface or a desktop.

When the notebook computer is in a closed state, the notebook computer is also in a dormant state, and the projection module is also in a closed state, so that the power consumption of the notebook computer can be reduced. When a user opens the notebook computer, the display side of the notebook computer rotates around the host side through the first connecting piece, and at the moment, the detection module in the notebook computer detects a first state parameter of the first connecting piece, wherein the first state parameter can be the rotation angle of the first connecting piece.

When the notebook computer determines that the rotation angle of the first connecting piece is greater than or equal to a preset threshold value, namely, the included angle between the display side and the host side of the notebook computer exceeds 60 degrees. At this time, the notebook computer is in a used state, and then the detection module in the notebook computer continues to detect the rotation angle of the first connecting piece.

For example, the notebook computer is in a closed state, and if the notebook computer is opened, the notebook computer is: when the included angle between the display side and the host side of the notebook computer is gradually increased, the detection module in the notebook computer detects the rotation angle of the first connecting piece, if the rotation angle reaches 90 degrees, the notebook computer is in a used state, then the detection module in the notebook computer continuously detects the rotation angle of the first connecting piece, and if the rotation angle reaches 120 degrees, the rotation angle of the first connecting piece reaches a preset threshold value.

The notebook computer can call the corresponding relation between the rotation angle stored in the storage module and the rotation parameter, then the notebook computer determines the rotation parameter corresponding to the rotation angle, for example, the rotation angle of the first connecting piece is 120 degrees, and the included angle between the keyboard surface of the notebook computer and the display screen is larger, so that the second image projected by the projection module on the notebook computer is switched to be displayed on the supporting surface by being displayed on the wall surface, and the display side of the notebook computer can shield the second image on the supporting surface. Of course, this second image is now also intended to be presented to a user near the support surface for viewing. The notebook computer will need to control the display of the second image.

The notebook computer determines that the rotation parameter corresponding to the rotation angle is 90 degrees. After obtaining the rotation parameter, the notebook computer controls the projection module to rotate the projected second image on the supporting surface by 90 degrees, so that the user can see a forward second image on the supporting surface, of course, here, the second image is rotated by 90 degrees clockwise, or rotated by 270 degrees clockwise, and the specific rotation angle may be determined according to a specific application scenario, for example, according to the orientation of the display screen of the notebook computer, or according to the rotation direction of the keyboard input surface of the notebook computer, and the like.

Specifically, after the projection module on the notebook computer vertically projects the second image onto the wall surface, the display side of the notebook computer continues to rotate, and the angle between the display side and the host side increases, at this time, the second image projected by the projection module is switched from being projected onto the wall surface to being projected onto a desktop on which the notebook computer or other electronic equipment is placed, when the rotation angle of the first connecting piece reaches 120 degrees, the projection module projects the second image onto the desktop of the notebook computer with the second image rotated by 90 degrees, so that the user on the right side of the notebook computer can view the second image forward, and of course, if the notebook computer is shifted to the left, the notebook computer rotates the second image by 270 degrees, so that the user on the left side of the notebook computer can view the forward second image on the supporting surface.

In the embodiment of the invention, when a user needs to switch the projection of the second image projected by the projection module of the notebook computer from the projection to the wall surface to the projection to the supporting surface, the notebook computer determines the rotation angle of the second image according to the rotation angle of the first connecting piece, and then the notebook computer automatically rotates the second image on the supporting surface, for example, by 90 degrees, 180 degrees or 270 degrees, so that the user around the supporting surface can see the forward second image, the projection mode of the projection module is more diversified, and the use of the projection module by the user is more convenient.

Certainly, if the contained angle between notebook computer's keyboard face and the display screen is when being rotated to 90 degrees by 160 degrees, the big preset threshold value of the rotation angle of this first connecting piece, at this moment, the projection module has adjusted the second image for the projection wall from the projection to the holding surface, this notebook computer also can be the same this moment according to the rotation angle of first connecting piece and determine a rotation parameter, rotation parameter this moment also can be rotatory 90 degrees, that is to say, when the projection module is with the second image projection on the wall, this notebook computer will control the projection module and rotate 90 degrees with the second image, can make the forward demonstration of second image on the wall like this, thereby convenience of customers watches.

Of course, in the embodiment of the present invention, the user may adjust the display position of the second image by rotating the second connector in addition to the first connector. For example, the projection module on the notebook computer projects the second image onto the wall surface just opposite to the wall surface at the current moment, then the user needs to project the second image onto the supporting surface, and at the moment, the user can adjust the second connecting piece to enable the second connecting piece to rotate around the fixed end of the display side, so that the second image is projected onto the wall surface and then is projected onto the supporting surface.

Then, the detection module in the notebook computer detects a second state parameter of the second connecting piece, where the second state parameter of the second connecting piece may also be a rotation angle of the second connecting piece, and if the rotation angle of the second connecting piece is greater than or equal to a preset threshold, for example, the rotation angle of the second connecting piece is greater than 30 degrees, the notebook computer determines a rotation parameter according to the rotation angle of the second connecting piece, where the rotation parameter is a rotation angle. For example, when the rotation angle of the second connecting member is 30 degrees, the notebook computer determines that the rotation angle in the rotation parameters is also 90 degrees. Then the notebook computer controls the projection module to rotate the second image by 90 degrees and then projects the second image onto the projection supporting surface, so that a user can see the rotation of the second image on the projection surface.

That is to say, after the rotation angle of the second connecting member is greater than a preset threshold, the notebook computer will determine that the second image is switched from projection on the wall surface to projection on the supporting surface, and therefore, the notebook computer will determine a rotation parameter, and then the notebook computer will rotate the second image based on the rotation parameter, so that the second image is rotated on the supporting surface, for example, 90 degrees on the supporting surface, or 270 degrees on the supporting surface, so that the user can see the second image on the supporting surface forward, which not only increases the projection mode of the projection module, but also makes the use of the projection module more convenient.

Of course, in this embodiment, in addition to determining the rotation parameter through the state parameter of the first connecting member and the state parameter of the second connecting member, the rotation parameter may be determined based on the orientation of the projection module, the orientation of the projection module may be determined according to an included angle between the projected image and the display screen, and of course, the orientation of the projection module may be determined according to an included angle between the projected image and the supporting surface of the notebook computer.

For example, the initial orientation of the projection module is that the projection image is parallel to the display surface of the display screen, an included angle exists between the projection image and the display surface of the display screen, the notebook computer determines that the orientation of the projection module changes, the notebook computer determines the orientation of the projection module, then determines a rotation parameter based on the orientation, and finally the notebook computer controls the projection module to adjust the second image to rotate on the projection surface based on the rotation parameter.

The above-described approaches may trigger the rotation of the projected image. The specific rotation manner has been described in detail in the first and second manners, and will not be described herein again.

In addition, it should be noted that, in the embodiment of the present invention, the triggering of the real-time process in the electronic device may be performed after an included angle exists between the first body and the second body of the electronic device, for example, when the electronic device is a notebook computer, the adjusting of the projected image may be performed after an included angle of 45 degrees or 60 degrees exists between the keyboard surface and the display surface of the notebook computer, so as to ensure that the scheme in the embodiment is only executed in the operating state of the notebook computer, and the scheme in the embodiment will not be executed when the notebook computer is in a shutdown state or a sleep state, so as to avoid power consumption waste on the notebook computer, and reduce component loss on the notebook computer.

In addition, it should be noted that, in the embodiment of the present invention, the position of the second display module 105, that is, the position of the projection module disposed on the notebook computer, may be set at an edge position of the display surface, and may also be set at a central position of the back surface of the display surface, and of course, the second display module 105 disposed at the central position and the edge position may both realize rotation of the second image projected by the second display module 105 on the second surface according to the technical solution in the above embodiments.

Further, in order to ensure the display effect of the second image on the second surface, in an embodiment of the present invention, the second display module 105 in the electronic device further includes:

a depth sensor 201 (shown in fig. 2) for detecting the width of an edge of the second image and the width between two parallel edges on the second image;

specifically, in the embodiment of the present invention, the depth sensor may be a binocular camera, the binocular camera respectively acquires corresponding images, for example, an image of a surface on which the second image is located, then the binocular camera performs image processing according to the respective acquired images, then the binocular camera determines a distance between the electronic device and the surface on which the second image is located based on the acquired images, and the electronic device calculates an edge width of the second image and a width between two parallel edges on the second image based on the coordinates of the acquired images and the determined distance.

The processing module is further configured to determine a correction parameter for correcting the second image according to the edge width of the second image detected by the depth sensor 201 and the width between two parallel edges on the second image, and send the correction parameter to the second display module 105, so that the second display module 105 adjusts the second image according to the correction parameter.

Specifically, after the second image is rotated on the second surface, the second image on the second surface may have image distortion, which may result in poor presentation of the second image, and therefore, in the embodiment of the present invention, the second display module 105 is provided with a depth sensor 201, and the depth sensor 201 can detect the widths of the upper edge and the lower edge of the second image on the second surface, and can also detect the width between the upper edge and the lower edge of the second surface, and the processing module in the electronic device can determine a correction parameter according to the two parameters. The correction parameter can be determined here on the basis of a correspondence.

After determining the correction parameter, the electronic device controls the second display module 105 to perform image correction on the second image, so that the second image has a better display effect on the second surface, and the user can view a clearer projection image.

Further, in the embodiment of the present invention, in addition to detecting the width of the second image by the depth sensor and performing correction of the second image, display of the second image may be controlled by the depth sensor.

Specifically, a gesture operation in a region where the second image is projected is acquired by the depth sensor, and display of the second image is adjusted based on the gesture operation. In particular, a first distance between the second image and the electronic device may be detected by the depth sensor, and a second distance between the user's finger in the area where the second image is projected and the electronic device may be detected, and if the second distance is equal to the first distance, the electronic device may control the second image to be enlarged or reduced; and if the second distance is smaller than the first distance, the electronic equipment maintains the current second image on the second side.

In addition, in the embodiment of the invention, the gesture operation of the user is acquired through the depth sensor, the contact position of the finger operation on the second image is determined, and the contact position is used as the display focus of the second image on the second surface; the electronic equipment controls the second display module to adjust the focus position of the second image to the display focus.

That is, the depth sensor is embodied as a binocular camera, and the binocular camera determines the contact position of the user's finger on the second image based on the captured image, but may be determined based on the image and coordinate analysis. After the depth sensor determines the contact position of the finger of the user on the second image, the depth sensor sends the contact position to the processing module, and then the processing module determines a display focus in the second image based on the contact position, takes the display focus as a new focus position of the second image, and adjusts the focus position of the second image to the display focus, so that the display focus of the second image projected on the second surface is the position pointed by the finger of the user. Therefore, the electronic equipment can automatically adjust the focus position of the second image according to the position pointed by the finger of the user, and the operation of the user is facilitated.

It should be noted here that, for the technical solution of performing focusing by using the depth sensor, the gesture of the user may not be needed to participate, the depth sensor detects the distance from the second surface, that is, the depth sensor can detect the distance between itself and the second surface, so as to determine the focal distance of the second image projected on the second surface according to the distance, and then the second display module 105 adjusts the projection of the second image according to the determined focal distance, that is, projects the second image according to the focal distance. Of course, since the distances from the depth sensor to the different edges of the projection area displaying the second image may not be equal, in the embodiment of the present invention, the depth sensor may detect the distances between the respective edges of the projection area and the depth sensor, then take the average value of the distances, and finally take the average value as the focal length. Automatic adjustment of the focal length of the second image can thus be achieved by means of the depth sensor.
