Description

Technical Field

[0001] This application relates to the field of projector technology, and in particular to a projector control method, device, electronic device, and readable storage medium. Background Technology

[0002] In recent years, with the continuous development of technology, desktop projector technology has become increasingly mature. Desktop projectors are typically placed on a flat table. Specifically, a laser module in the desktop projector emits a laser beam that projects onto the projection area. When a user taps on the projection area with their finger, the fingertip reflects the laser, forming a light spot. This light spot is captured by an infrared camera module in the desktop projector, and by locating the light spot, the corresponding coordinates can be found on the projected content to generate a corresponding response.

[0003] However, in environments with strong natural light, when a user performs a click operation in the projection area, the infrared camera module captures photos with too much ambient light, affecting the recognition of light spots in the photos and resulting in low accuracy of light spot recognition. Summary of the Invention

[0006] The ambient light intensity is collected based on the ambient light sensor, and it is verified whether the ambient light intensity is greater than a first preset light intensity.

[0007] If the ambient light intensity is found to be greater than the first preset light intensity, the projection content of the projection module and the display content of the display screen will be swapped.

[0008] If the ambient light intensity is found to be no greater than the first preset light intensity, the display brightness of the screen and the projection brightness of the projection module are adjusted according to the ambient light intensity, wherein both the display brightness and the projection brightness are positively correlated with the ambient light intensity.

[0014] If no user-triggered operation on the information confirmation identifier is detected within a preset period, then the step of replacing the projection content of the projection module and the display content of the display screen is executed.

[0015] If a user triggers an operation on the information confirmation identifier within a preset period, then the step of determining the trigger status of the information confirmation identifier based on the user's trigger operation on the information confirmation identifier is executed.

[0017] Verify whether the ambient light intensity is less than a preset reference light intensity, wherein the reference light intensity is less than the first preset light intensity;

[0018] If the ambient light intensity is found to be less than the reference light intensity, the projected content of the projection module and the displayed content of the display screen are restored to their state before the image content replacement.

[0019] Optionally, before the step of replacing the projected content of the projection module with the displayed content of the display screen, the projector control method further includes:

[0020] Verify whether the ambient light intensity is greater than a second preset light intensity, wherein the second preset light intensity is greater than the first preset light intensity;

[0021] If the ambient light intensity is found to be no greater than the second preset light intensity, then the step of replacing the image content of the projection module and the display content of the screen is executed;

[0022] If the ambient light intensity is found to be greater than the second preset light intensity, the projection screen of the projection module is turned off to stop the projection module from projecting the content, and the display screen is split into a first display area and a second display area.

[0023] The display content is displayed on the first display area, and the projected content is displayed on the second display area.

[0024] Optionally, both the first display area and the second display area are provided with area size adjustment indicators, and the projector control method further includes:

[0025] In response to a user's touch gesture triggered by adjusting the size of the area, the sliding direction and sliding distance of the touch gesture are obtained;

[0026] Based on the sliding direction and sliding distance of the touch gesture, determine the adjustment direction and adjustment size of the first display area or the second display area;

[0027] Based on the adjustment direction and the adjustment size, the display area size of the first display area or the second display area is adjusted on the display screen.

[0028] Optionally, the step of adjusting the display brightness of the screen and the projection brightness of the projection module according to the ambient light intensity includes:

[0029] Based on the ambient light intensity, find the target display brightness corresponding to the display screen and the target projection brightness corresponding to the projection module;

[0030] The display brightness of the screen is adjusted to the target display brightness, and the projection brightness of the projection module is adjusted to the target projection brightness.

[0033] The first adjustment module is used to replace the projection content of the projection module and the display content of the display screen if the ambient light intensity is found to be greater than the first preset light intensity.

[0034] The second adjustment module is used to adjust the display brightness of the display screen and the projection brightness of the projection module according to the ambient light intensity if the ambient light intensity is not greater than the first preset light intensity. The display brightness and the projection brightness are both positively correlated with the ambient light intensity.

[0035] This application also provides an electronic device, which is a physical device, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the steps of the projector control method as described above.

[0038] This application provides a projector control method. First, based on the ambient light intensity collected by the ambient light sensor in the desktop projector, the method verifies whether the ambient light intensity is greater than a first preset light intensity. If the ambient light intensity is greater than the first preset light intensity, it indicates that the ambient light intensity has a significant impact on the light spot recognition of the projection area. In this case, the projected content of the projection module in the desktop projector needs to be replaced with the displayed content on the screen. The user can then interact directly on the screen, eliminating the need for light spot recognition. Conversely, if the ambient light intensity is not greater than the first preset light intensity, it indicates that the ambient light intensity has a smaller impact on the light spot recognition of the projection area. In this case, adjusting the projection brightness of the projection module increases the light in the projection area captured by the infrared camera module when capturing light spots, thereby improving the accuracy of light spot recognition in environments with strong natural light. Simultaneously, adjusting the display brightness of the screen ensures the display effect in environments with strong natural light, thus solving the technical problem of low accuracy in light spot recognition of desktop projectors in environments with strong natural light.

[0049] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example 1

[0051] In recent years, with the continuous development of technology, desktop projector technology has become increasingly mature. Desktop projectors are typically placed on a flat table. Specifically, a laser module in the desktop projector emits a laser beam that projects onto the projection area. When a user taps on the projection area with their finger, the fingertip reflects the laser, forming a light spot. This light spot is captured by an infrared camera module in the desktop projector, and by locating the light spot, the corresponding coordinates can be found on the projected content to generate a corresponding response.

[0052] However, in environments with strong natural light, when a user performs a click operation in the projection area, the infrared camera module captures photos with too much ambient light, affecting the recognition of light spots in the photos and resulting in low accuracy of light spot recognition.

[0053] As an example, Figure 1 This is a schematic front view of the structure of a desktop projector used in an embodiment of this application. Figure 2 This is a schematic perspective view of the structure of a desktop projector used in an embodiment of this application, such as... Figure 1 and Figure 2 As shown, the desktop projector includes a projector and camera module mounting area 1, a display screen 2, a laser module 3, an infrared camera module 4, a projection module 5, an RGB (Red, Green, Blue) camera module 6, a motherboard 7, a projection area 8, and a camera module 9. The camera module 9 includes a camera and an ALS (Ambient Light Sensor). The display screen 2 is a touch-screen display that allows user interaction. The display screen 2 displays content A, and the projection area 8 displays content B. This example does not limit the structure of the desktop projector, and the projector control methods mentioned below are not limited to this desktop projector.

[0054] Based on this, this application proposes a projector control method according to a first embodiment, applied to a desktop projector. The desktop projector includes an ambient light sensor, a display screen, and a projection module. Please refer to... Figure 3 The projector control method includes:

[0055] Step S10: Collect ambient light intensity based on the ambient light sensor, and verify whether the ambient light intensity is greater than a first preset light intensity;

[0056] It should be noted that the ambient light sensor is used to sense the light conditions of the surrounding environment. The desktop projector can be equipped with one ambient light sensor or multiple ambient light sensors. This embodiment does not make a specific limitation on this. The first preset light intensity refers to the light intensity corresponding to the maximum projection brightness of the projection module.

[0057] As an example, when the desktop projector is equipped with multiple ambient light sensors, the step of collecting ambient light intensity based on the ambient light sensors includes: obtaining the sub-ambient light intensity collected by each ambient light sensor, calculating the average ambient light intensity based on each sub-ambient light intensity, and using the average ambient light intensity as the ambient light intensity. Alternatively, the sub-ambient light intensity that appears most frequently among the sub-ambient light intensities can be used as the ambient light intensity. This example does not specifically limit this.

[0058] Step S20: If the ambient light intensity is found to be greater than the first preset light intensity, the projection content of the projection module and the display content of the display screen are swapped.

[0059] It should be noted that the projected content refers to the image content that needs to be projected onto the projection area, while the displayed content refers to the image content that needs to be displayed on the display screen.

[0060] As an example, two storage data packets can be set. The first storage data packet stores the relevant projection parameters of the projection content projected by the projection module. The projection parameters may include the projection screen size, projection screen resolution, etc. The second storage data packet stores the relevant display parameters of the display screen displaying the content. The display parameters may include the display screen size, display screen resolution, etc. In this case, the step of replacing the image content of the projection content of the projection module and the display content of the display screen includes: extracting the first storage data packet from the data storage area of ​​the projection module and the second storage data packet from the data storage area of ​​the display screen; moving the second storage data packet from the data storage area of ​​the display screen to the data storage area of ​​the projection module; and moving the first storage data packet from the data storage area of ​​the projection module to the data storage area of ​​the display screen, so as to replace the image content of the projection content of the projection module and the display content of the display screen.

[0061] As another example, the projection content of the projection module and the display content of the display screen can be replaced by changing the communication addresses of the projection module and the display screen. The projection module is a first communication address, which corresponds to the projection content, and the display screen is a second communication address, which corresponds to the display content. In this case, the step of replacing the projection content of the projection module and the display content of the display screen includes: adjusting the communication address of the projection module from the first communication address to the second communication address, and adjusting the communication address of the display screen from the second communication address to the first communication address, so as to replace the projection content of the projection module and the display content of the display screen. This example does not have specific limitations.

[0062] Step S30: If the ambient light intensity is found to be no greater than the first preset light intensity, then adjust the display brightness of the display screen and the projection brightness of the projection module according to the ambient light intensity, wherein the display brightness and the projection brightness are both positively correlated with the ambient light intensity.

[0063] This application provides a projector control method. First, based on the ambient light intensity collected by the ambient light sensor in the desktop projector, the method checks whether the ambient light intensity is greater than a first preset light intensity. If the ambient light intensity is greater than the first preset light intensity, it indicates that the ambient light intensity has a significant impact on the light spot recognition in the projection area. In this case, the projected content of the projection module in the desktop projector needs to be replaced with the displayed content on the screen. The user can then interact directly on the screen, eliminating the need for light spot recognition. Conversely, if the ambient light intensity is not greater than the first preset light intensity, it indicates that the ambient light intensity has a smaller impact on the light spot recognition in the projection area. In this case, adjusting the projection brightness of the projection module increases the light in the projection area captured by the infrared camera module when capturing light spots, thereby improving the accuracy of light spot recognition in environments with strong natural light. Simultaneously, adjusting the display brightness of the screen ensures the display effect in environments with strong natural light, thus solving the technical problem of low accuracy in light spot recognition by desktop projectors in environments with strong natural light.

[0064] In one possible implementation, the step of replacing the projected content of the projection module with the displayed content of the screen includes:

[0065] Step E21: Obtain the projection screen elements and projection screen coordinate system of the projected content, and obtain the display screen elements and display screen coordinate system of the displayed content;

[0066] Step E22: Swap the projected image elements and the displayed image elements, and simultaneously swap the projected image coordinate system and the displayed image coordinate system, so as to replace the projected content of the projection module and the displayed content of the display screen.

[0067] In this implementation, by simultaneously exchanging the projection screen elements of the projected content and the display screen elements of the pre-display content with the display screen coordinate system, the original display content can adapt to the size of the projection area after the screen content of the projection module and the display content of the display screen are replaced.

[0068] In one possible implementation, before the step of replacing the projected content of the projection module with the displayed content of the screen, the projector control method further includes:

[0069] Step S21: Display pop-up information on the projection screen of the projection module, wherein the pop-up information is located in a pop-up bar with an information confirmation icon.

[0070] It should be noted that this pop-up message is used to confirm whether the user agrees to the replacement of the screen display content and the projection content of the projection module.

[0071] As an example, the pop-up information displayed on the projection screen of the projection module can be displayed in the center of the projection screen, at a preset display position, or at any position on the projection screen. This example does not impose any specific limitations on this.

[0072] Step S22: Based on the user's triggering operation on the information confirmation identifier, determine the triggering state of the information confirmation identifier, wherein the triggering state includes a confirmation state and a cancellation state;

[0073] It should be noted that the trigger operation refers to the user's operation on the information confirmation mark. The trigger state includes a confirm state and a cancel state. The confirm state is used to indicate to the user that they accept the replacement of the screen content displayed on the display screen and the projection content projected by the projection module. The cancel state is used to indicate to the user that they do not accept the replacement of the screen content displayed on the display screen and the projection content projected by the projection module.

[0074] Step S23: If the trigger state is verified to be the determined state, then the step of replacing the projection content of the projection module and the display content of the display screen is executed.

[0075] In this embodiment, before replacing the content displayed on the screen and the content projected by the projection module, a pop-up window needs to be displayed on the projection screen of the projection module. The pop-up window contains a confirmation indicator to indicate whether the user accepts the replacement of the content displayed on the screen and the projection screen. The triggering state of the confirmation indicator is determined based on the user's action on it. If the triggering state is confirmed, it means the user accepts the replacement, and the replacement operation is performed. By displaying the pop-up window on the projection screen, the user is promptly alerted that the ambient light intensity significantly affects the light spot recognition in the projection area, and the user is instructed to take appropriate action. This overcomes the influence of ambient light intensity on light spot recognition, improving the accuracy of light spot recognition in environments with strong natural light.

[0076] In one possible implementation, before the step of determining the triggering state of the information confirmation identifier based on the user's triggering operation on the information confirmation identifier, the projector control method further includes:

[0077] Step S221. If no user-triggered operation on the information confirmation identifier is detected within a preset period, then the step of replacing the projection content of the projection module and the display content of the screen is executed;

[0078] Step S222: If a user trigger operation on the information confirmation identifier is detected within a preset period, then the step of determining the trigger status of the information confirmation identifier based on the user's trigger operation on the information confirmation identifier is executed.

[0079] In this embodiment, if no user trigger operation on the information confirmation identifier is detected within a preset period, the user is assumed to accept the replacement of the display content on the screen and the projection content on the projection module. The operation of replacing the display content on the screen and the projection content on the projection module can be directly executed. However, if a user trigger operation on the information confirmation identifier is detected within the preset period, the operation of determining the trigger status of the information confirmation identifier based on the user's trigger operation will proceed normally. This avoids the technical problem of low accuracy of light spot recognition under the ambient light intensity caused by the user not triggering the information confirmation identifier for a long time, thus ensuring the normal operation of the projector control process.

[0080] In one possible implementation, after the step of replacing the projected content of the projection module with the displayed content of the screen, the projector control method further includes:

[0081] Step E21: Verify whether the ambient light intensity is less than a preset reference light intensity, wherein the reference light intensity is less than the first preset light intensity;

[0082] It should be noted that this reference light intensity is used to determine whether the projected content of the projection module and the displayed content of the screen can be restored to their state before the image content was replaced.

[0083] Step E22: If the ambient light intensity is found to be less than the reference light intensity, then the projected content of the projection module and the displayed content of the display screen are restored to their state before the image content replacement.

[0084] In this embodiment, after replacing the display content on the screen and the projection content on the projection module, it is necessary to verify whether the ambient light intensity is less than a preset reference light intensity to determine whether it is necessary to restore the projection content on the projection module and the display content on the screen to their state before the content replacement. If the ambient light intensity is less than the reference light intensity, it indicates that there is a stable operating effect in the projection area of ​​the projection module. In this case, the projection content on the projection module and the display content on the screen are restored to their state before the content replacement. This embodiment overcomes the technical problem that when the ambient light intensity is near the first preset light intensity, the projection content on the projection module and the display content on the screen are repeatedly replaced, affecting the projection and display effects, and thus affecting the user experience.

[0085] To avoid the influence of ambient light intensity on the light spot position recognition, users need to manually increase the projection brightness of the projection area. This requires multiple adjustments and tests to achieve a projection brightness where the light spot position recognition is unaffected by the current ambient light intensity, resulting in low efficiency in brightness adjustment. Similarly, to avoid the influence of ambient light intensity on the display screen's display effect, users also need to manually increase the display brightness of the display area, requiring multiple adjustments to determine the optimal display brightness under that ambient light intensity. This also leads to low efficiency in display brightness adjustment.

[0086] In one possible implementation, the step of adjusting the display brightness of the screen and the projection brightness of the projection module based on the ambient light intensity includes:

[0087] Step S31: Based on the ambient light intensity, find the target display brightness corresponding to the display screen and the target projection brightness corresponding to the projection module;

[0088] It should be noted that the target display brightness refers to the display brightness that the display screen needs to achieve to ensure that the display effect of the display screen is not affected by the ambient light intensity; the target projection brightness refers to the projection brightness that the projection module needs to achieve to ensure that the projection effect of the projection module is not affected by the ambient light intensity.

[0089] As an example, a database can be set up to record the correspondence between the ambient light intensity and the target display brightness, as well as the correspondence between the ambient light intensity and the target projection brightness. In this case, the step of finding the target display brightness corresponding to the display screen and the target projection brightness corresponding to the projection module based on the ambient light intensity includes: using the ambient light intensity as an index, searching the database for the target display brightness corresponding to the display screen and the target projection brightness corresponding to the projection module.

[0090] Step S32: Adjust the display brightness of the display screen to the target display brightness, and adjust the projection brightness of the projection module to the target projection brightness.

[0091] In this embodiment, the target display brightness of the display screen and the target projection brightness of the projection module under the ambient light intensity are determined by searching. The display brightness of the display screen and the projection brightness of the projection module are then adjusted to the target display brightness. This enables an automated adjustment process for both the display and projection brightness without human intervention. Furthermore, the search method allows for rapid matching of the required display brightness of the display screen and the required projection brightness of the projection module under the ambient light intensity, further improving the adjustment efficiency of both display and projection brightness.

[0092] Example 2

[0093] Based on the first embodiment of this application, in another embodiment of this application, the same or similar content as in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 4 Before the step of replacing the projected content of the projection module with the displayed content of the screen, the projector control method further includes:

[0094] Step A10: Verify whether the ambient light intensity is greater than the second preset light intensity, wherein the second preset light intensity is greater than the first preset light intensity;

[0095] Step A20: If the ambient light intensity is found to be no greater than the second preset light intensity, then the step of replacing the projection content of the projection module and the display content of the display screen is executed.

[0096] Step A30: If the ambient light intensity is found to be greater than the second preset light intensity, the projection screen of the projection module is turned off to stop the projection module from projecting the projection content, and the display screen is split into two screens to obtain a first display area and a second display area.

[0097] As an example, the step of splitting the display screen to obtain a first display area and a second display area can be to split the display screen vertically to obtain a first display area and a second display area, or to split the display screen horizontally to obtain a first display area and a second display area, or to split the display screen diagonally. This example does not specifically limit this step.

[0098] Step A40: Display the display content on the first display area and display the projected content on the second display area.

[0099] In this embodiment, before replacing the display content on the screen and the projection content on the projection module, it is first necessary to check whether the ambient light intensity is greater than the second preset light intensity to determine whether the projection effect of the projection module will be too poor due to the influence of the ambient light intensity. If the ambient light intensity is not greater than the second preset light intensity, it means that the projection effect of the projection module will not be too poor due to the influence of the ambient light intensity, and the display content on the screen and the projection content on the projection module are replaced. If the ambient light intensity is greater than the second preset light intensity, it means that the projection effect of the projection module will be too poor due to the influence of the ambient light intensity, and the projection image of the projection module needs to be turned off to stop the projection module from continuing to project. The display screen is then split into a first display area and a second display area. The display content that is already displayed on the screen is displayed in the first display area, and the projection content that was originally displayed on the projection module is displayed in the second display area, thereby overcoming the technical problem of poor projection effect caused by excessive ambient light intensity.

[0100] For example, please refer to Figure 1 and Figure 5Initially, display screen 2 shows image content A, while projection area 8 shows image content B. When the ambient light intensity is detected to be greater than the second preset light intensity, the display screen is divided into the first display area (corresponding to...). Figure 5 (left side) and second display area (corresponding to) Figure 5 (to the right of the first display area) Display content A in the first display area and display content B in the second display area.

[0101] In one possible implementation, both the first display area and the second display area are provided with area size adjustment indicators, and the projector control method further includes:

[0102] Step B10: In response to a touch gesture triggered by the user's adjustment of the area size indicator, obtain the sliding direction and sliding distance of the touch gesture;

[0103] It should be noted that the sliding direction can be any direction. Taking a rectangular display screen as an example, the sliding direction can be parallel to the short axis of the display screen, parallel to the long axis of the display screen, or parallel to the diagonal of the display screen. This embodiment does not make specific limitations in this regard. The endpoint of the touch gesture can be within the display area of ​​the display screen or at the edge of the display area of ​​the display screen. This embodiment does not make specific limitations in this regard.

[0104] Step B20: Determine the adjustment direction and adjustment size of the first display area or the second display area based on the sliding direction and sliding distance of the touch gesture;

[0105] Step B30: Adjust the display area size of the first display area or the second display area on the display screen according to the adjustment direction and the adjustment size.

[0106] In this embodiment, firstly, in response to a user's touch gesture triggered by the area size adjustment indicator, the sliding direction and sliding distance of the touch gesture are obtained. Then, the adjusted display area size is determined based on the sliding direction and sliding distance. This embodiment sets area size adjustment indicators on the first display area and the second display area respectively, allowing the user to freely adjust the display area size of the first and second display areas, thereby improving the flexibility of display area size adjustment.

[0107] To aid in understanding the technical concept or principle of this application, a specific embodiment is provided:

[0108] Taking the display screen showing video content (e.g., video calls) and the projection module projecting interactive content (e.g., reading, drawing, etc.) as an example, the projector control flow in this specific embodiment is as follows:

[0109] 1. When the user uses the projector, the environmental sensor continuously monitors the ambient light and sends the detected ALS value (corresponding to the ambient light intensity) back to the motherboard chip for processing.

[0110] 2. When the ALS value is less than the critical value b (corresponding to the first preset light intensity mentioned above), the motherboard sends a command to remind the user. After the user confirms the exchange of content between the projection part (corresponding to the projection module mentioned above) and the display part (corresponding to the display screen mentioned above), the content of the projection part and the display part is exchanged. That is, the video content that should be displayed on the display screen is displayed through the projection module; the interactive content that should be displayed on the projection module is displayed through the display screen. At this time, the user watches the video in the projection area and interacts with the projector through the touch screen in the display area of ​​the display screen.

[0111] 3. When the ALS value is greater than the critical value c (corresponding to the second preset light intensity mentioned above), the motherboard sends a command to turn off the projection screen and remind the user to move to a place with weaker light to continue using the projector.
