detailed description

In order to facilitate the understanding of those skilled in the art, the present application is further described below in conjunction with the accompanying drawings, and is not intended to limit the scope of the application.

Referring to FIG. 1 , an embodiment of the present application provides a terminal control method, where the method includes: step 200 and step 400.

In step 200, in a case where the terminal is placed with the screen facing up, an image corresponding to the target placement area is acquired.

In the embodiment of the present application, a terminal provided with one side as a screen and one side as a non-screen material as an example is taken as an example. The front-facing position means that the terminal is placed with the screen facing upward. In addition, the terminal may also be a terminal having a display screen on both sides, or a terminal having other display screen setting modes.

In step 400, the acquired image is displayed through the screen.

With the terminal control method provided by the present application, when the terminal is placed in standby, the image corresponding to the target placement area can be obtained according to the placed position, thereby increasing the degree of integration between the terminal and the environment, and the terminal can reduce the exposure loss of the terminal through the above solution. The risk can also meet the needs of today's users to personalize the terminal.

In the step 200, the acquiring an image corresponding to the target placement area includes: acquiring an initial background image by using a camera; the shooting range of the initial background image includes the target placement area; and acquiring a height h of the terminal from the target placement area An angle θ (such as the camera angle of view FOE in FIG. 3); determining, according to the acquired height h and the angle θ, an image of a partial region in the initial background image as an image corresponding to the target placement region.

For example, an exemplary calculation is:

Determining the image of a partial region in the initial background image includes:

Obtaining the length a of the initial background image captured by the background image, a=2*h*tan(θ/2);

Obtaining an image length range b of the target placement area; wherein, in the initial background image, the image length range of the target placement area is taken from the middle, and the ratio is b/(a/2);

The calculation method on the width is similar to the length b method; for example:

Obtaining the length c of the initial background image captured by the background image, c=2*h*tan(θ/2);

Obtaining an image length range d of the target placement area; wherein, in the initial background image, the image length range of the target placement area is taken from the middle, and the ratio is d/(c/2);

The area whose length b is d is the image area corresponding to the target placement area, that is, the position M area occupied by the terminal in FIG.

In step 200, after the image corresponding to the target placement area is acquired, the blurring process is performed on the boundary of the image corresponding to the target placement area.

The method further includes: step 300 and step 500.

In step 300, the color value corresponding to the target placement area is obtained.

In step 500, the acquired color values are displayed by a color changeable material in the bezel area.

The method further includes: obtaining a color value corresponding to the target placement area when the terminal is placed with the back side facing up; and displaying the acquired color value by the color changeable material on the back side of the terminal.

The color value corresponding to the target placement area is obtained by: acquiring an initial background image by using a camera; the shooting range of the initial background image includes the target placement area; determining the initial background image according to the acquired height h and the angle The image of the partial area is an image corresponding to the target placement area; wherein the angle is determined by the angle of view of the camera; and the color value corresponding to the target placement area is obtained according to the image corresponding to the target placement area.

The method for obtaining the color value is: calculating an average value of color values of all the pixel points in the image corresponding to the target placement area, and using the average value as the color value corresponding to the target placement area.

The mobile phone camouflage method provided by the present application is applicable to all terminal products. In the embodiment of the present application, when the terminal product starts the camouflage mode, the current bearing surface image is taken, and the calculation, image processing, and processing are performed according to parameters such as the background image taken, the position of the terminal when shooting, the camera angle of view, and the screen size of the terminal. The image and color values are presented in an optimized manner on at least one of the screen, the bezel, and the back cover. The optimization includes such parts: First, the liquid crystal display (LCD) brightness is appropriately reduced according to the surrounding environment, and the environment is consistent with the surrounding environment, so that the terminal and the loader are integrated, and the power saving effect is achieved. At the same time, in order to save power, it is also possible to reduce the main frequency by appropriate means; secondly, for a terminal with a bezel, the bezel and the back cover of the terminal back cover are treated like the back cover, that is, if they are LCD or other displayable colors According to the color value and the surrounding environment, the color value is adjusted appropriately on the frame and the back cover of the terminal. Thirdly, since the material that can display the color is generally expensive, the temperature can also be selected. The color-changing terminal housing uses some applications in the background of the terminal to make the mobile phone rise to the corresponding temperature, and the color change is controlled by the difference in temperature. Through the application, the risk of loss of terminal exposure can be reduced, and the requirements of personalized terminals of today's users can also be met.

The following description is made in conjunction with an exemplary implementation scenario.

Referring to FIG. 2, an embodiment of the present application provides a terminal control method, including: step S101 to step S108.

In step S101, a request for the user to initiate the masquerading mode is received, which may be by way of, but not limited to, a menu, a gesture, and a shortcut key.

In step S102, an image taken by the user above the position where the terminal is expected to be placed is acquired, and may be, but not limited to, a button, a gesture, a shortcut key, and the like. If the terminal is facing up, take a picture with the rear camera; if the terminal is facing up, use the front camera to take a picture.

In step S103, the bearer image is stored in a specific area.

In step S104, the distance between the camera terminal and the carrier is detected and recorded.

In step S105, the position occupied by the terminal in the captured surface image of the carrier is calculated according to parameters such as the angle of view of the camera, the distance between the terminal and the surface of the carrier, and the size of the terminal screen.

For calculations, see the method shown in 3: where h is the distance from the surface of the terminal.

As shown in FIG. 3, according to the camera view angle FOE and the distance h of the surface of the terminal carrier, the image area of the surface of the carrier can be calculated, and according to the screen size of the terminal, the position area of the image projected by the terminal onto the surface of the carrier can be calculated, that is, The area of the image that will be covered after the terminal is placed on the carrier, as indicated by the area indicated by M in the figure.

In step S106, based on the output of the calculation system in S105, the image of the position area M occupied by the terminal is extracted from the surface image of the carrier stored in S103, and Gaussian blur or other blurring processing is performed on the image boundary.

In step S107, an optimal color value is calculated as a color value of the bezel or the back cover based on the surface image of the carrier. The optimal color value here can take the most color value directly, and other methods of calculating the optimal color value can also be used.

In step S108, if the terminal is face up, the image of the M area output by S106 is displayed on the terminal screen, and the optimal color value calculated by the frame S107 is displayed; if the terminal is the reverse side, the rear case is on the rear case. The optimal color value calculated by S107 is shown.

In step S108, the following optimization method is used: firstly, the LCD brightness is appropriately reduced according to the surrounding environment to ensure consistency with the surrounding environment, so that the terminal and the carrier are integrated, and the power saving effect is achieved, and at the same time, for the festival. Electricity, can also be reduced by appropriate frequency and other schemes; second, for the framed terminal, the frame and the back cover of the terminal back cover are treated the same, that is, if they are LCD or other material that can display color, then According to the color value processed above and the surrounding environment, the color value is appropriately adjusted and displayed on the frame and the rear cover of the terminal. Third, since the material that can display the color is generally expensive, the terminal housing with temperature change can also be selected. Using the terminal to run some applications in the background, the mobile phone is raised to the corresponding temperature, and the color change is controlled by the difference in temperature.

It is also possible to provide a heat-generating material or a heat-generating component in a portion close to the outer casing, thereby causing a change in color of the temperature-sensitive terminal casing by the heat-generating material.

Of course, if there are problems in other subsystems other than the display system and the screen image or border color value is not successfully obtained, we can also select the appropriate image or color value for display from the preset image library. It can also be used as an optional way to personalize the terminal.

After the above processing, the terminal screen, the frame, the back cover and the carrier are integrated, thereby reducing the risk of loss of exposure, and also meeting the needs of the personalized setting terminal of today's users.

Referring to FIG. 4, the terminal control apparatus provided by the embodiment of the present application may include four sub-modules: a photographing system, a distance detecting system, a computing system, and an image processing system.

In the shooting system, the user records the surface image of the carrier when taking pictures in the camouflage mode. When the phone is facing up, use the rear camera system and use the front camera system when the phone is facing up.

The distance detecting system detects the distance between the recording terminal and the surface of the carrier when the user takes a picture in the camouflage mode.

The computing system calculates the position occupied by the terminal in the image of the surface of the captured object according to parameters such as the angle of view of the camera, the distance between the terminal and the surface of the carrier, and the size of the terminal screen.

Image processing system, consisting of two parts,

One is screen image processing, that is, extracting an image of the position occupied by the terminal from the surface image of the carrier according to the output of the computing system, and performing Gaussian blur or other blurring processing on the image boundary;

The second is the border/back cover color value processing. If there is a color-changable border or back cover at the terminal, the optimal color value is calculated according to the surface image of the carrier as the color value of the border or the back cover. The optimal color value here can take the most color value directly, or other methods of calculating the optimal color value can be used.

The display system displays the image outputted by the first part of the image processing system on the screen, and sets the border or the back cover to the optimal color value calculated by the second part of the image processing system.

Of course, if there are problems in other subsystems other than the display system and the screen image or border color value is not successfully obtained, we can also select the appropriate image or color value for display from the preset image library. It can also be used as an exemplary way for a user to personalize the terminal.
