Description

Image display method and electronic device

technical field

The invention relates to the field of electronic technology, in particular to an image display method and electronic equipment.

Background technique

Interaction with humans is an important function of smart devices such as robots. Interaction mainly includes two parts: signal input and output. The most common way of signal output is to use images to represent various information.

Generally speaking, in order to interact with people, one method is to set a display screen on the robot, so that the input and output of signals can be realized through touch. But the disadvantage of this method is that it can only interact with people at close range. People can only see the content on the screen or touch the screen when they walk in front of the robot. Another method is to use a projector to project the information you want the user to see onto a screen or wall, so that the user can see the relevant information from a longer distance. But if you can't find a suitable projection surface, or the ambient light is too strong, the projection effect of the projector will be greatly affected.

It can be seen that screen display and projection display have their own advantages and disadvantages. How to combine screen display and projection display so as to have the advantages of both display methods has become an urgent problem to be solved at this stage.

In a specific implementation process, the projection device 110 may be a projector, the driving device 130 may be a motor, and the projection screen 120 may be driven by the driving device 130 to move (for example: move up and down, or move left and right, or flip).

In the specific implementation process, as shown in FIG. 1, when the projection screen 120 moves to the first position in front of the projection device 110 (for example: the position directly in front of the lens of the projection device 110), the electronic device 100 enters the first working mode (that is: screen display mode), the projection screen 120 can project images on the projection screen 120 .

In a specific implementation process, when the electronic device 100 is in the first working mode, the projection screen 120 projects an image on the back of the projection screen 120 through “rear projection”, and the user can see the image from the front of the projection screen 120 .

In a specific implementation process, the projection screen 120 is a semi-transparent baffle, and its light transmittance is 50% to 60%, (for example: high transmittance LowE glass with a light transmittance of 50% to 60% can be used), so that When the projection device 110 projects an image on the projection screen 120 , the user can see the image on the front of the projection screen 120 , but the user cannot see the internal structure of the electronic device 100 through the projection screen 120 .

In the specific implementation process, as shown in FIG. 2, when the projection screen 120 moves to the second position (ie: any position except the first position), the electronic device 100 enters the second working mode (ie: projection display mode) , the projection screen 120 can project an image on an imaging object 200 , wherein the imaging object 200 is located outside the electronic device 100 .

For example, the second position may be any other position except the position directly in front of the lens of the projection device 110, for example, it may be the left front, right front, directly behind, left rear, right rear, upper, lower of the projection device 110 lens wait.

In a specific implementation process, the imaging object 200 is an object outside the electronic device 100 (for example: a wall, or a curtain, etc.). The surface of the imaging object 200 should be as flat as possible, so as to obtain a better projection effect.

In the embodiment of the present application, the electronic device 100 has two working modes (namely: screen display mode and projection display mode), and a driving device 130 drives the projection screen 120 to move, thereby switching the working mode of the electronic device 100 . Therefore, it effectively solves the technical problem that the screen display and the projection display cannot be combined in the prior art, and realizes the technical effect of combining the screen display and the projection display so as to have the advantages of both display modes.

The control device 140 is further configured to send a first control command to the drive device 130 when the light intensity is greater than or equal to a preset intensity, and send a second control command to the drive device 130 when the light intensity is less than a preset intensity.

In the specific implementation process, when the light intensity of the current environment is too strong (ie: the current environment is too bright), if the electronic device 100 adopts the second working mode (ie: projection display mode), the imaging effect will be affected, and the user cannot A clear image is seen on the imaging object 200 . Therefore, when the light intensity of the current environment is too strong, the control device 140 can send a first control instruction to the driving device 130, thereby controlling the electronic device 100 to enter the first working mode (ie: screen display mode), so as to control the projection device 110 to display the The image is projected on the projection screen 120, thereby ensuring that the user can see a clear image.

Therefore, when the surface roughness of the imaging object 200 is low, the control device 140 can send a first control command to the drive device 130, thereby controlling the electronic device 100 to enter the first working mode (ie: screen display mode), so as to control the projection device 110 The image is projected on the projection screen 120, so that the user can see a clear image.

In a specific implementation process, when the surface finish of the imaging object 200 is relatively high (that is, relatively flat), the electronic device 100 can use the second working mode (ie: projection display mode), so as to project an image onto the imaging object 200 , so that the user can see a large-size image on the imaging object 200, which meets the viewing needs of multiple users and users at a long distance.

As an optional implementation manner, the control device 140 is also used for:

In a specific implementation process, the user can control the electronic device 100 to enter different working modes through different body movements or facial expressions.

For example, the first preset action may be "clasping fists with both hands", and the second preset action may be "separate hands". When the action occurs, it will enter the first working mode, and if it is collected that the user makes an action of "separating the hands", it will enter the second working mode.

For another example, the first preset action can be "smile", and the second preset action can be "close your eyes". , then enter the first working mode; if it is collected that the user makes an action of "closing eyes", then enter the second working mode.

Here, the first preset action and the second preset action may have many situations, and no examples will be given here.

As an optional implementation manner, the electronic device 100 further includes:

A touch panel (for example: a capacitive touch panel or a resistive touch panel), covered on the outer surface of the projection screen 120, and connected to the control device 140;

The control device 140 is further configured to obtain a user's touch operation on the touch panel when the electronic device 100 is in the first working mode, and send a second control command to the drive device 130 when the touch operation satisfies a preset condition.

In the specific implementation process, when the electronic device 100 is in the first working mode, it can project an interactive interface to the projection screen 120, and a button is displayed on the interactive interface. The electronic device 100 then enters the second working mode. Moreover, a physical button is also provided on the electronic device 100 . After the electronic device 100 enters the second working mode, if the control device 140 detects that the user triggers the physical button, it will control the electronic device 100 to return to the first working mode.

In addition, it is also possible to directly control the electronic device 100 to enter the first working mode or the second working mode by pressing the physical button. For example: when the electronic device 100 is in the first working mode, if the control device 140 detects that the user triggers the physical button, it will control the electronic device 100 to enter the second working mode; when the electronic device 100 is in the second working mode, if the control The apparatus 140 detects that the user triggers the physical button, and then controls the electronic device 100 to enter the first working mode.

In the specific implementation process, when the light intensity of the current environment is too strong (i.e. the current environment is too bright), if the self-balancing vehicle adopts the second working mode (i.e. projection display mode), the imaging effect will be affected, and the user cannot A clear image is seen on the imaging object 200 . Therefore, when the light intensity of the current environment is too strong, the control device 140 can send a first control instruction to the drive device 130, thereby controlling the self-balancing vehicle to enter the first working mode (ie: screen display mode), so as to control the projection device 110 to display the The image is projected on the projection screen 120, thereby ensuring that the user can see a clear image.

In the specific implementation process, when the light intensity of the current environment is weak (ie: the current environment is dark), the self-balancing vehicle can use the second working mode (ie: projection display mode), so as to project the image onto the imaging object 200, so that the user can see a large-size image on the imaging object 200, which meets the viewing needs of multiple users and long-distance users.

As an optional implementation, the self-balancing vehicle also includes:

An image acquisition device 160 (for example: a camera), connected to the control device 140, for collecting a third image including the imaging object 200, and providing the third image to the control device 140;

The control device 140 is also used to determine the surface roughness of the imaging object 200 based on the third image, and to send a first control command to the driving device 130 when the surface roughness is lower than a preset smoothness, and to send a first control command to the driving device 130 when the surface roughness is higher than or equal to the preset smoothness , send a second control command to the driving device 130 .

In the specific implementation process, if the surface finish of the imaged object 200 is low (ie: uneven), then if the self-balancing vehicle adopts the second working mode (ie: projection display mode), the imaging effect will be affected, and the user cannot A clear image is seen on object 200. Therefore, when the surface finish of the imaged object 200 is relatively low, the control device 140 can send a first control command to the driving device 130, thereby controlling the self-balancing vehicle to enter the first working mode (ie: screen display mode) to control the projection device 110 The image is projected on the projection screen 120, so that the user can see a clear image.

In the specific implementation process, when the surface finish of the imaging object 200 is relatively high (that is: relatively flat), the self-balancing vehicle can adopt the second working mode (ie: projection display mode), so as to project an image onto the imaging object 200 , so that the user can see a large-size image on the imaging object 200, which meets the viewing needs of multiple users and users at a long distance.

As an optional implementation manner, the control device 140 is also used for:

Gather the fourth image that comprises user's action (for example: body action, or expression action) by image acquisition device 160; Based on the fourth image, determine the user's action; When the user's action is the first preset action, send to the drive 130 sends a first control instruction; when the user's action is a second preset action, sends a second control instruction to the driving device 130 .

In the specific implementation process, the user can control the self-balancing vehicle to enter different working modes through different body movements or facial expressions.

For example, the first preset action can be "clasping fists with both hands", and the second preset action can be "hands apart". When the action occurs, it will enter the first working mode, and if it is collected that the user makes an action of "separating the hands", it will enter the second working mode.

For another example, the first preset action can be "smile", and the second preset action can be "close your eyes". , then enter the first working mode; if it is collected that the user makes an action of "closing eyes", then enter the second working mode.

Here, the first preset action and the second preset action may have many situations, and no more examples will be given here.

As an optional implementation, the self-balancing vehicle also includes:

A touch panel (for example: a capacitive touch panel or a resistive touch panel), covered on the outer surface of the projection screen 120, and connected to the control device 140;

The control device 140 is also used to obtain the user's touch operation on the touch panel when the self-balancing vehicle is in the first working mode, and send a second control instruction to the drive device 130 when the touch operation meets a preset condition.

In the specific implementation process, when the self-balancing vehicle is in the first working mode, an interactive interface can be projected to the projection screen 120, and a button is displayed on the interactive interface. If the control device 140 detects that the user triggers the button through the touch panel, then control The self-balancing car then enters the second working mode. Moreover, there is a physical button on the self-balancing vehicle. After the self-balancing vehicle enters the second working mode, if the control device 140 detects that the user triggers the physical button, it will control the self-balancing vehicle to return to the first working mode.

In addition, the self-balancing vehicle can be directly controlled to enter the first working mode or the second working mode by pressing the physical button. For example: when the self-balancing car is in the first working mode, if the control device 140 detects that the user triggers the physical button, it will control the self-balancing car to enter the second working mode; when the self-balancing car is in the second working mode, if the control The device 140 detects that the user triggers the physical button, and then controls the self-balancing vehicle to enter the first working mode.

At this time, the projection device 110 can Images are projected on the projection screen 120 .

In the specific implementation process, the second control instruction is used to control the driving device 130 to move the projection screen 120 to the second position in front of the projection device 110, so that the self-balancing vehicle can enter the second working mode. At this time, the projection device 110 can An image is projected on the imaging object 200 .

It should be noted here that step S201 and step S202 do not have a sequence, and are two parallel and independent steps.
