Technical Field

[0001] This application belongs to the field of image display, and particularly relates to an image display method and device for a front camera. Background Art

[0002] When going out, since it is inconvenient to carry a mirror with you, users can turn on the front camera of the electronic device to act as a mirror. That is, the user unlocks the electronic device, clicks to start the camera application, and adjusts the camera application to the front shooting mode, so as to use the picture displayed in the front shooting mode as a mirror.

[0003] However, in the above method, when the user uses the front camera as a mirror, the user needs to perform multiple operations to trigger the electronic device to display the picture in the front shooting mode, so as to use this picture as a mirror. Moreover, when the user uses the front camera as a mirror, other users can see the picture displayed on the electronic device. Therefore, there is a risk of leakage of the user's privacy information; thus, the convenience and security of the user using the front camera function of the electronic device are relatively poor. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide an image display method and device for a front camera, which can solve the problem of relatively poor convenience and security of the user using the front camera function of the electronic device.

[0005] In a first aspect, the embodiments of this application provide an image display method for a front camera. The image display method for the front camera includes: when the electronic device is in the screen-off state, if the information obtained through the camera of the electronic device meets the first preset condition, display the shooting picture of the front camera on the screen, and cover a black mask layer with a target transparency on the shooting picture.

[0006] In a second aspect, the embodiments of this application provide an image display device for a front camera. The image display device for the front camera includes: a display module. The display module is used to, when the electronic device is in the screen-off state, if the information obtained through the camera of the electronic device meets the first preset condition, display the shooting picture of the front camera on the screen, and cover a black mask layer with a target transparency on the shooting picture.

[0007] In a third aspect, the embodiments of this application provide an electronic device. The electronic device includes a processor and a memory. The memory stores a program or instruction that can run on the processor. When the program or instruction is executed by the processor, the steps of the method described in the first aspect are implemented.

[0008] Fourthly, an embodiment of the present application provides a readable storage medium, on which a program or instruction is stored, and when the program or instruction is executed by a processor, the steps of the method described in the first aspect are implemented.

[0009] Fifthly, an embodiment of the present application provides a chip, which includes a processor and a communication interface. The communication interface is coupled to the processor, and the processor is used to run a program or instruction to implement the method described in the first aspect.

[0010] Sixthly, an embodiment of the present application provides a computer program product, which is stored in a storage medium and is executed by at least one processor to implement the method described in the first aspect.

[0011] In the embodiment of the present application, when the electronic device is in the screen-off state, the distance between the user's face and the screen of the electronic device can be obtained through the front camera. Thus, when the distance between the user's face and the screen of the electronic device is less than or equal to the first threshold, the electronic device can display the captured image of the front camera in the screen-off state, and a black mask layer with a target transparency is covered on the captured image of the front camera. In this solution, when the distance between the user's face and the screen of the electronic device is less than or equal to the first threshold, the electronic device determines / considers that the user needs to use the front camera function of the electronic device, for example, to view the user's image through the front camera.

[0023] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0024] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order different from those illustrated or described herein, and the objects distinguished by "first", "second", etc. generally belong to the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0025] Next, in conjunction with the accompanying drawings, the image display method for a front camera provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0026] When going out, since it is inconvenient to carry a mirror with you, when the user needs to use a mirror, the user can unlock the electronic device, start an application with a shooting function in the electronic device (such as a camera application), and adjust the camera application to the front shooting mode, so as to display the current facial state of the user in real time through the shooting preview interface captured by the front camera, thus acting as a mirror for use.

[0027] However, in the existing solutions, when the user uses the front camera to act as a mirror, the user needs to perform multiple operations on the electronic device to trigger the electronic device to display the shooting preview interface captured by the front camera, which makes the steps that the user needs to operate rather cumbersome, and the electronic device needs to consume more time to respond to the multiple operations of the user, resulting in poor convenience when the user uses the front camera function of the electronic device.

[0028] In the embodiments of the present application, when the electronic device is in the screen-off state, the electronic device can obtain the distance between the user's face and the screen of the electronic device through the front camera. Thus, when the distance between the user's face and the screen of the electronic device is less than or equal to the first threshold, the electronic device can display the shooting screen of the front camera in the screen-off state, and cover a black mask layer with a target transparency on the shooting screen captured by the front camera. In this solution, when the distance between the user's face and the screen of the electronic device is less than or equal to the first threshold, the electronic device determines / considers that the user needs to use the front camera function of the electronic device, for example, to view the user's image through the front camera. At this time, the electronic device can directly display the shooting screen of the front camera, enabling the user to clearly view the shooting screen of the front camera, reducing the operations that the user needs to perform, and reducing the time consumed by the user's operations; covering a black mask layer with a target transparency on the shooting screen captured by the front camera reduces the risk of leakage of the user's privacy information while enabling the user to clearly view the shooting screen; thereby improving the convenience and security of the user when using the front camera function of the electronic device.

[0029] The embodiments of the present application provide a method for displaying an image of a front camera. Figure 1 The flowchart of a method for displaying an image of a front camera provided by the embodiments of the present application is shown. As Figure 1 shown, the method for displaying an image of a front camera provided by the embodiments of the present application may include the following steps 201 and 202.

[0030] Step 201: When the electronic device is in the screen-off state, the electronic device obtains information through the camera of the electronic device.

[0031] Optionally, in a scenario of an embodiment of the present application, when the electronic device is in the screen-off state, the electronic device can turn on the front camera and run the front camera function in the background to collect / capture images in real time through the front camera, so as to obtain the captured images of the front camera.

[0032] Optionally, in another scenario of an embodiment of the present application, when the electronic device is in the screen-off state, the electronic device can turn on the front camera and the rear camera, and run the front camera function and the rear camera function in the background to collect / capture images in real time through the front camera, so as to obtain the captured images of the front camera, and collect / capture images through the rear camera, so as to obtain the captured images of the rear camera.

[0033] Optionally, in an embodiment of the present application, when the electronic device is in the screen-off state and before the electronic device obtains information through the camera of the electronic device, the user can input to the screen-off mirror control in the settings application, or the user can input to the physical button / physical button combination of the electronic device to trigger the electronic device to turn on the screen-off mirror mode. In the screen-off mirror mode, if the electronic device detects that the electronic device is in the screen-off state, then the electronic device can turn on the camera of the electronic device to obtain information through the camera of the electronic device.

[0034] Step 202: If the information obtained by the electronic device through the camera of the electronic device meets the first preset condition, then display the captured image of the front camera on the screen, and overlay a black mask layer with a target transparency on the captured image.

[0035] In an embodiment of the present application, the above first preset condition is that the distance between the user's face captured by the front camera and the screen of the electronic device is less than or equal to a threshold.

[0036] Optionally, in an implementation manner of an embodiment of the present application, when the distance is less than or equal to the first threshold, the electronic device can display the captured image of the front camera on the screen in the screen-off state, and overlay a black mask layer with a target transparency on the captured image. Specifically, the electronic device can first overlay a first layer on the screen in the screen-off state, that is, the layer for displaying the captured image of the front camera, and then overlay a second layer on this layer, that is, the black mask layer with the target transparency.

[0037] Optionally, in another implementation manner of the embodiments of the present application, when the distance is less than or equal to the first threshold, the electronic device may display the captured image of the front camera on the screen in the lit screen state, and overlay a black mask with a target transparency on the captured image. Specifically, the electronic device may run the front camera in the foreground, that is, display / jump to the shooting interface of the front camera, so as to display the captured image of the front camera in the shooting interface, and overlay a black mask with a target transparency on the entire shooting interface.

[0038] Optionally, in the embodiments of the present application, the above-mentioned target transparency may be any one of the following: the transparency preset by the user, the default transparency of the electronic device system, and the transparency determined according to the number of users detected by the cameras (front and rear cameras) of the electronic device (the more users, the lower the transparency).

[0039] Optionally, in the embodiments of the present application, after the electronic device overlays a black mask with a target transparency on the captured image, the color information (such as color saturation, color brightness, etc.) of the captured image displayed on the screen may be suppressed, so that while displaying the captured image of the front camera, the off-screen state of the electronic device can be simulated.

[0040] Optionally, in an implementation manner of the embodiments of the present application, in combination with Figure 1 , as Figure 2 shown, the above step 202 may be specifically implemented by the following steps 202a and 202b.

[0041] Step 202a: The electronic device obtains the distance between the user's face and the screen of the electronic device through the front camera of the electronic device.

[0042] Optionally, in the embodiments of the present application, the electronic device may detect whether the captured image of the front camera contains a user face image. When the captured image of the front camera contains a user face image, the electronic device may obtain the distance between the user's face and the screen of the electronic device through the front camera.

[0043] Optionally, in the embodiments of the present application, the electronic device may match the user face image included in the captured image of the front camera with a preset face image. When the two face images match, the electronic device may obtain the distance between the user's face and the screen of the electronic device through the front camera.

[0044] Optionally, in the embodiments of the present application, the electronic device may, according to the real-time captured image of the front camera, establish a spatial coordinate system through 3D measurement technology, respectively obtain the spatial coordinate positions of the user's face and the screen of the electronic device in the space, and calculate the distance between the user's face and the screen of the electronic device in the space according to the two spatial coordinate positions.

[0045] Step 202b: When the distance is less than or equal to the first threshold, the electronic device displays the captured image of the front camera on the screen, and covers the captured image with a black mask layer having a target transparency.

[0046] In the embodiment of the present application, the above-mentioned target transparency is a preset transparency.

[0047] Optionally, in the embodiment of the present application, while the electronic device displays the captured image of the front camera on the screen, it can generate a black mask layer having the same size as the screen and the target transparency, and cover it on the displayed captured image, so that the finally displayed image on the screen is the captured image covered with the black mask layer, thereby enabling the image displayed by the electronic device in the off-screen mirror mode to simulate the image displayed by the electronic device in the ordinary off-screen state in terms of color. It should be noted that the image displayed in the off-screen mirror mode refers to the image captured by the front camera of the electronic device in real time, and the image displayed in the ordinary off-screen state refers to the image shown by using the off-screen as a mirror, so the former has better clarity than the latter.

[0048] Exemplarily, taking the electronic device as a mobile phone as an example. As Figure 3 shown in (a) of, when the mobile phone detects that the distance between the user's face and the mobile phone screen is less than or equal to the first threshold, the mobile phone can display the real-time captured image of the front camera on the screen, and simultaneously generate a black mask layer with a target transparency of 50%, and cover it on the real-time captured image displayed on the screen, to obtain the image shown in (b) of Figure 3 , that is, the finally displayed image on the screen is the captured image covered with the black mask layer. It can be understood that the covered black mask layer of the mobile phone does not affect the clarity of the real-time captured image of the front camera displayed on the mobile phone screen, but reduces the brightness of the real-time captured image, so that while the user can clearly view the captured image of the front camera displayed on the mobile phone screen, the user's privacy is protected from being leaked.

[0049] Optionally, in another implementation manner of the embodiment of the present application, in combination with Figure 1 , as Figure 4 shown, the above-mentioned step 202 can be specifically implemented by the following step 202c and step 202d.

[0050] Step 202c: The electronic device obtains the distance between the user's face and the screen of the electronic device through the front camera of the electronic device, and obtains the number of target users within the first range through the front camera and the rear camera of the electronic device.

[0051] In the embodiment of the present application, the above-mentioned first range is the shooting range of the front camera and the rear camera.

[0052] It can be understood that the number of users in the above first range is the sum of the number of users in the captured image of the front camera and the number of users in the captured image of the rear camera.

[0053] Optionally, in the embodiment of the present application, the electronic device obtains the captured image of the front camera through the front camera, so that the number of users in the captured image of the front camera can be obtained through face recognition technology according to the captured image of the front camera.

[0054] Optionally, in the embodiment of the present application, the electronic device obtains the captured image of the rear camera through the rear camera, so that the number of users in the captured image of the rear camera can be obtained through people counting technology according to the captured image of the rear camera.

[0055] Optionally, in the embodiment of the present application, after "obtaining the number of target users in the first range through the front camera and the rear camera of the electronic device" in the above step 202c, the image display method of the front camera provided by the embodiment of the present application further includes the following step 301.

[0056] Step 301: When the distance is less than or equal to the first threshold and the number of target users is less than or equal to the second threshold, if the orientation of the target user relative to the electronic device meets the second preset condition, the electronic device displays the captured image of the front camera on the screen.

[0057] In the embodiment of the present application, the above second preset condition includes at least one of the following: the included angle value between the position where the target user is located and the screen of the electronic device is outside the target included angle range, and the distance between the target user and the electronic device is greater than or equal to the third threshold; the target included angle range is the visual angle range of the user with respect to the screen.

[0058] It can be understood that when the number of users is less than or equal to the second threshold, the electronic device determines that the current environment where the user is located is an environment with very few people, that is, there are very few users around the user. At this time, if the orientation of the target user relative to the electronic device meets the second preset condition, that is, due to the influence of the included angle or the distance between the position where the target user is located and the electronic device, the target user cannot directly view the screen of the electronic device, the electronic device can directly display the captured image of the front camera on the screen, without covering the black layer with the target transparency on the captured image, so that the user can clearly view the captured image of the front camera, and at the same time, there is no need to worry about other users viewing the captured image of the front camera, thereby reducing the risk of user privacy leakage.

[0059] Step 202d: When the distance is less than or equal to the first threshold and the number of target users is greater than the second threshold, the electronic device displays the captured image of the front camera on the screen and covers a black mask with a target transparency on the captured image.

[0060] In the embodiment of the present application, the above-mentioned target transparency is positively correlated with the number of target users.

[0061] Optionally, in the embodiment of the present application, the relationship between the above-mentioned target transparency and the number of users is as shown in Formula 1, that is, the electronic device calculates the target transparency of the black mask based on the number of users in the first range using Formula 1.

[0062] y1 = k1n + b1 Formula 1

[0063] Where y1 is the transparency of the black mask (i.e., the target transparency), n is the number of users, k1 is a fixed constant less than 0, and b1 is a preset fixed constant.

[0064] It should be noted that as the number of users obtained by the electronic device increases, the target transparency of the black mask decreases based on b1. That is, when the number of users is greater than the second threshold, the more users there are, the lower the transparency of the black mask displayed by the electronic device on the captured image of the front camera. When the target transparency is equal to a threshold value (for example, the target transparency is 20%), the value of the target transparency no longer decreases with the increase in the number of users to ensure the clarity of the captured image displayed by the electronic device for the user to view.

[0065] It should be noted that for the specific solution of the electronic device to display the captured image of the front camera on the screen and cover a black mask with a target transparency on the captured image, reference can be made to the description in the above embodiment, and details will not be elaborated here.

[0066] In the embodiment of the present application, the electronic device obtains the number of users in the first range through the front camera and the rear camera, and obtains the target transparency of the black mask based on the number of users. That is, the electronic device judges the current environment where the user is located by the number of users obtained. Thus, when the environment where the user is located is an environment with a large number of people, the electronic device can set the target transparency of the black mask to a lower value to reduce the detailed display of the captured image of the front camera, making it difficult for other users except the user to clearly view the captured image of the front camera, thereby protecting the user's privacy and enabling the user to better use the front camera function in different places.

[0067] In an embodiment of the present application, when the distance is less than or equal to the first threshold, if the number of users is greater than the second threshold, the embodiment of the present application may execute the above steps 202c and 202d. If the number of users is less than or equal to the second threshold, the embodiment of the present application may execute the above steps 202c and 301.

[0068] An embodiment of the present application provides an image display method for a front camera. When the electronic device is in the screen-off state, it can obtain the distance between the user's face and the screen of the electronic device through the front camera. Thus, when the distance between the user's face and the screen of the electronic device is less than or equal to the first threshold, the electronic device can display the captured image of the front camera in the screen-off state, and cover a black mask with a target transparency on the captured image of the front camera. In this solution, when the distance between the user's face and the screen of the electronic device is less than or equal to the first threshold, the electronic device determines / considers that the user needs to use the front camera function of the electronic device, such as viewing the user's image through the front camera. At this time, the electronic device can directly display the captured image of the front camera, enabling the user to clearly view the captured image of the front camera, reducing the operations that the user needs to perform, and reducing the time consumed by the user's operations; covering a black mask with a target transparency on the captured image of the front camera reduces the risk of leakage of the user's privacy information while enabling the user to clearly view the captured image; thereby improving the convenience and security of the user using the front camera function of the electronic device.

[0069] Optionally, in an embodiment of the present application, in combination with Figure 1 , as Figure 5 shown, after the above step 202, the image display method for the front camera provided by the embodiment of the present application further includes the following steps 401 and 402.

[0070] Step 401: When detecting a touch input on the first area of the screen by the user, the electronic device obtains the touch area and touch force of the first area.

[0071] Optionally, in an embodiment of the present application, the above touch input is any possible form of input such as a click input, a slide input, or a long press input by the user on the first area.

[0072] It should be noted that the above touch area is the area touched by the user's finger or other objects that can be sensed by the capacitive screen on the screen. The above touch force is the force applied by the user when performing a touch input on the screen of the electronic device.

[0073] Step 402: When the touch area of the first area is the first area, the electronic device adjusts the transparency of the second area in the black mask from the target transparency to the first transparency according to the touch force.

[0074] In the embodiment of the present application, the second area is the area in the black mask layer corresponding to the first area and having a positive correlation with the touch area of the first area; the first transparency is greater than the target transparency and has a positive correlation with the touch force.

[0075] In the embodiment of the present application, the area of the black mask layer whose transparency is to be adjusted corresponds to the first area touched by the user. The size of the touch area determines the size of the area of the black mask layer whose transparency is to be adjusted, and the size of the touch force determines the transparency of the area of the black mask layer whose transparency is to be adjusted. Among them, the touch area has a positive correlation with the area of the black mask layer whose transparency is to be adjusted, that is, the larger the touch area, the larger the area of the black mask layer whose transparency is to be adjusted; the touch force has a positive correlation with the transparency of the area of the black mask layer whose transparency is to be adjusted, that is, the larger the touch force, the greater the transparency of the area of the black mask layer whose transparency is to be adjusted.

[0076] Optionally, in the embodiment of the present application, the electronic device may use Formula 2 to calculate the area of the area of the black mask layer whose transparency is to be adjusted according to the touch area, so as to adjust the transparency of the area of this size (i.e., the second area) in the black mask layer.

[0077] y2 = k2x2 + b2 Formula 2

[0078] Wherein, y2 is the area of the area of the black mask layer whose transparency is to be adjusted, x2 is the touch area of the first area, k2 is a fixed constant greater than 0, and b2 is a fixed constant.

[0079] Exemplarily, in combination with Figure 3 in (b), as shown in Figure 6 in (a), when the touch area of the user on the first area is the second area, the area of the area of the black mask layer whose transparency is to be adjusted corresponding to the touch area is smaller. As shown in Figure 6 in (b), when the touch area of the user on the first area is the third area, the area of the area of the black mask layer whose transparency is to be adjusted corresponding to the touch area is larger, where the second area is smaller than the third area.

[0080] Optionally, in the embodiment of the present application, the user can perform a left swipe input or a right swipe input on the screen of the electronic device, so that the electronic device adjusts the transparency of the black mask layer covering the captured image, so that the electronic device can better display the captured image of the front camera to meet the user's brightness requirement for viewing the captured image.

[0081] Optionally, in the embodiments of the present application, the electronic device may use Equation 3 to calculate the first transparency of the second area according to the touch force, so that the transparency of the second area is adjusted from the target transparency to the first transparency.

[0082] y3 = k3x3 + b3 Equation 3

[0083] Wherein, y3 is the first transparency of the second area, x3 is the touch force of the user on the first area, k3 is a fixed constant greater than 0, and b3 is the target transparency of the second area.

[0084] Exemplarily, in combination with Figure 3 in (b), as shown in Figure 7 in (a), when the touch force of the user on the first area is the first force value, the mobile phone can make a small adjustment (for example, 10%) on the basis of the target transparency; as shown in Figure 7 in (b), when the touch force of the user on the first area is the second force value, the mobile phone can make a large adjustment (for example, 30%) on the basis of the target transparency, wherein the first force value is less than the second force value.

[0085] In the embodiments of the present application, the electronic device may determine the area of the area where the transparency of the black mask layer is to be adjusted according to the touch area of the touch input of the user on the first area, and determine the transparency size of the area where the transparency of the black mask layer is to be adjusted according to the touch force, so as to accurately and quickly adjust the transparency of the area in the black mask layer, thereby improving the convenience and flexibility of the electronic device in adjusting the transparency, and at the same time making the display screen of the electronic device have diversity.

[0086] Optionally, in the embodiments of the present application, after the above step 402, the image display method of the front camera provided by the embodiments of the present application further includes the following steps 403 to 405.

[0087] Step 403: The electronic device displays a target mark in the second area.

[0088] In the embodiments of the present application, the above target mark is used to mark the second area with the first transparency in the black mask layer.

[0089] Optionally, in the embodiments of the present application, the electronic device may display the target mark in a preset shape, or display the target mark according to the shape of the second area. Wherein, the shape of the target mark may include, but is not limited to, at least one of the following shapes: circle, triangle, rhombus, and irregular shape.

[0090] Optionally, in the embodiments of the present application, after the electronic device adjusts the transparency of the second area, the user can input to the second area (such as click input or long - press input) so that the electronic device can display a target mark on the second area.

[0091] Step 404: The electronic device receives the first input from the user.

[0092] In the embodiments of the present application, the above - mentioned first input is an input for the user to drag the target mark from the second area to the third area in the black mask layer.

[0093] Step 405: In response to the first input, the electronic device adjusts the transparency of the third area from the target transparency to the first transparency.

[0094] It should be noted that the area of the above - mentioned third area is the same as the area of the second area.

[0095] Exemplarily, in combination with Figure 7 (b) in Figure 8 As shown, when the user moves the target mark from the second area (such as the mouth area) to the third area (such as the eye area), the mobile phone can use the position where the target mark moves as the center of the circle, and determine the area with the same area as the second area as the third area, so as to adjust the transparency of the third area to the first transparency of the second area.
