Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one.
The screen projection control method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, fig. 1 is a flowchart of a screen projection control method provided in an embodiment of the present application, and is applied to an electronic device. As shown in fig. 1, the method may include the steps of:
step 11: after the electronic equipment is connected with the display terminal, the target brightness value of the screen projection content is obtained.
In the embodiment of the application, the display terminal is specifically a screen projection display terminal and is used for displaying screen projection contents. After the screen-casting event is triggered, the electronic equipment can be connected with the display terminal in a wireless mode or in a wired mode. For example, the electronic device may establish a connection with the display terminal through a wireless network, such as WiFi; or the electronic equipment can be connected with the display terminal through a USB data line.
Optionally, the screen shot content may include, but is not limited to, video, photos, text content, and the like.
Optionally, when the electronic device acquires the target brightness value of the screen projection content, the target brightness value may be acquired by detecting the brightness of the environment, or may be acquired by manual setting, which is not limited herein.
Step 12: and adjusting the brightness of the screen projection content by using the target brightness value to obtain target display content.
It can be understood that after the target brightness value of the screen projection content is obtained, the electronic device can adjust the brightness of the screen projection content, so that the target display content projected to the display terminal can realize the effect of brightness change when the display terminal displays the target display content.
Step 13: and transmitting the target display content to the display terminal.
In the embodiment of the application, the display terminal is used for displaying the target display content, that is, the display terminal displays the target display content after receiving the target display content. As for the transmission mode of the target display content, the transmission can be performed through a wireless data transmission medium, and the transmission can also be performed through a wired data transmission medium.
Note that the display terminal in the embodiment of the present application may be a large screen display without an automatic brightness adjustment function. In this way, in the screen projection application, the brightness sensing capability of the electronic equipment is utilized, and the capability of automatically adjusting the brightness of the large screen display without the brightness automatic adjustment function can be given.
According to the screen projection control method, after the electronic equipment is connected with the display terminal, the target brightness value of the screen projection content can be obtained, brightness adjustment is conducted on the screen projection content by means of the target brightness value, the target display content is obtained, the target display content is transmitted to the display terminal, and the target display content is displayed by the display terminal. Therefore, the screen projection content with the adjusted brightness can be transmitted to the display terminal to be displayed, so that the display effect of the screen projection content on the display terminal can be ensured even if the display terminal does not have the brightness adjustment function, and the display effect of the screen projection content is improved.
In the embodiment of the present application, the electronic device may have a photosensitive unit, such as a light sensor, to perform ambient light brightness detection. The process of acquiring the target brightness value of the screen-projected content may include:
the method comprises the steps that electronic equipment obtains a first environment light brightness value of a current environment; for example, a first ambient light brightness value may be obtained by performing ambient light brightness detection on a current environment by the photosensitive unit;
the electronic equipment determines a target brightness value corresponding to the first ambient light brightness value according to the corresponding relation between the preset ambient light brightness and the content brightness value.
Therefore, by means of the acquired brightness value of the current environment and the corresponding relation between the preset environment brightness and the content brightness value, the target brightness value matched with the current environment can be accurately acquired, the screen projection content is further adjusted according to the target brightness value, and the effect that the brightness of the screen projection content displayed on the display terminal is adjusted along with the change of the environment can be achieved.
It should be noted that the correspondence between the environmental light brightness and the content brightness value may be a correspondence table, and is pre-stored in the electronic device, so as to directly determine the content brightness value corresponding to the current environmental light brightness. For the corresponding relation table, when the ambient light brightness is in different ranges, the corresponding content brightness values are different and can be set based on actual requirements. Alternatively, the correspondence between the environmental light brightness and the content brightness value may be a relationship function, so as to obtain the content brightness value by calculation according to the environmental light brightness. The relation function may be set based on actual requirements, such as a straight line function.
For example, taking an electronic device as a mobile phone and a display terminal as a television without a brightness adjustment function as an example, assuming that a current backlight brightness value of the television is X, a brightness value of a current environment obtained by the mobile phone is relatively low, and screen projection content displayed in the television needs to be adjusted, the mobile phone may obtain a brightness value obtained by detecting ambient brightness of a photosensitive unit, obtain a target brightness value Y of the screen projection content, and perform brightness adjustment, i.e., scaling display brightness, on the screen projection content by using the target brightness value Y, directly send an obtained data packet of the screen projection content to the television after adjustment, and directly display the screen projection content with the brightness adjusted to achieve an effect of adjusting the brightness along with the environment. It is particularly emphasized that the backlight brightness value X of the television set does not change during this process.
In one embodiment, the electronic device may set a selectable switch option that, when turned on, may adjust the brightness of the projected content without changing color by obtaining light-sensitive brightness information, such as an ambient light brightness value. If the projection screen display terminal has the function of automatically adjusting the brightness, the switch option can be selected to be closed; or when the color effect of the compressed screen projection content is not ideal due to the hardware of the electronic equipment, the switch option can be selected to be closed, so that better compatibility is realized.
In another embodiment, because the electronic device, such as a mobile phone, is flexible to move, when the electronic device is used to adjust the brightness of the content displayed on the large-screen display by projecting the screen, the orientation of the light-sensitive unit of the electronic device can be kept consistent with the visual field of human eyes, so that the brightness in the visual field covered by the eyes can be more accurately sensed, and the accuracy of brightness adjustment can be improved.
In addition, considering that the backlight brightness value of the electronic device may change with the change of the ambient light, and the display terminal may not have the automatic brightness adjustment function, the electronic device may correct the brightness value of the screen projection content by using a difference between the backlight brightness value of the electronic device changing with the ambient light and the backlight brightness value of the display terminal, so as to achieve an effect that the screen projection content on the display terminal changes with the ambient light.
Optionally, the process of acquiring the target brightness value of the screen-shot content may include:
the method comprises the steps that the electronic equipment obtains a difference value between a backlight brightness value of the electronic equipment and a backlight brightness value of a display terminal;
and the electronic equipment corrects the brightness value of the screen projection content by using the difference value to obtain a target brightness value of the screen projection content. The manner of this modification includes, but is not limited to, subtracting the difference from the brightness value of the projected content to obtain a target brightness value of the projected content. Of course, a corresponding adjustment coefficient may also be determined according to the difference, and a target brightness value of the screen projection content may be obtained according to the adjustment coefficient.
Therefore, the target brightness value of the screen projection content is obtained by means of the difference value between the backlight brightness value of the electronic equipment and the backlight brightness value of the display terminal, and the effect that the screen projection content on the display terminal changes along with the ambient light can be achieved when the screen projection content is adjusted according to the target brightness value.
In the embodiment of the application, the electronic device can have a function of manually adjusting the brightness. For example, when the user perceives that the brightness of the screen projection content needs to be adjusted, a control instruction can be input to the electronic device so that the electronic device can adjust the brightness of the screen projection content. The process of acquiring the target brightness value of the screen-projected content may include:
the electronic equipment receives a first input of a user; for example, the first input may be a sliding operation on a display interface of the electronic device, a pressing operation of a specific virtual key, a voice input, or the like;
the electronic device acquires a target brightness value of the screen projection content in response to the first input.
Therefore, by means of user input, the matched target brightness value can be accurately acquired, the screen projection content is further adjusted according to the target brightness value, and the brightness of the screen projection content displayed on the display terminal can meet the brightness requirement of the user.
In the embodiment of the present application, when the brightness of the screen projection content is adjusted, the brightness may be adjusted by correcting RGB three-channel values or channels related to brightness, which are respectively described as follows.
Optionally, the process of adjusting the brightness of the screen projection content may include:
the electronic equipment acquires a first coefficient, wherein the first coefficient is the ratio of a target brightness value to a first backlight brightness value of the electronic equipment;
and the electronic equipment corrects the RGB three-channel numerical value of each pixel point of the screen projection content by using the first coefficient to obtain the target display content.
Therefore, the brightness of the screen projection content is adjusted through the first coefficient, namely the brightness ratio, and the brightness of the screen projection content can be reduced on the premise of not changing the display color of the screen projection content.
It should be noted that the first backlight brightness value may be a maximum backlight brightness value of the electronic device, or a preset backlight brightness value. When the RGB three-channel value of each pixel of the screen projection content is corrected by using the first coefficient, the R channel value, the G channel value, and the B channel value of each pixel of the screen projection content may be multiplied by the first coefficient, respectively, to obtain the target display content.
For example, taking screen projection content in RGB format as an example, if the maximum backlight brightness value of the electronic device is L, the obtained target brightness value of the screen projection content is a (0< a < L), and the content of a certain pixel point of the screen projection content is white (R:255, G:255, C:255), then during brightness adjustment, the a/L is multiplied by the RGB three-channel numerical value of the pixel point to obtain corresponding new content (R:255a/L ). And after the RGB three-channel numerical value of each pixel point of the screen projection content is corrected by the a/L, the obtained target display content can be transmitted to the display terminal for displaying, at the moment, the brightness of the screen projection content is correspondingly reduced, but the display color cannot be changed.
It can be understood that, in the embodiment of the present application, besides the screen projection content in RGB format, brightness adjustment may be performed on screen projection content in other formats, and at this time, each channel does not need to be corrected, and only channels related to brightness, such as a brightness channel and a lightness channel, need to be adjusted to implement brightness scaling.
Optionally, the process of adjusting the brightness of the screen projection content may include:
the electronic equipment acquires a second coefficient, wherein the second coefficient is the ratio of the target brightness value to a second backlight brightness value of the electronic equipment;
and the electronic equipment corrects the channel value related to the brightness of the screen projection content by using the second coefficient to obtain the target display content.
Therefore, the brightness of the screen projection content is adjusted through the second coefficient, namely the brightness ratio, and the brightness of the screen projection content can be reduced on the premise of not changing the display color of the screen projection content.
It should be noted that the second backlight brightness value may be a maximum backlight brightness value of the electronic device, or a preset backlight brightness value. The second backlight brightness value may be the same as or different from the first backlight brightness value. When the value of the brightness-related channel of the projected content is corrected by using the second coefficient, the value of the brightness-related channel of the projected content may be multiplied by the second coefficient to obtain the target display content.
For example, taking the projection content in HSL (Hue, Saturation, brightness; Hue, Saturation, brightness)/HSV (Hue, Saturation, brightness; Hue, Saturation, Value) format as an example, if the maximum backlight brightness Value of the electronic device is L, and the target brightness Value of the projection content is a (0< a < L), then the luminance of the projection content obtained at this time may be correspondingly decreased by multiplying the L channel Value/V channel Value by a/L during the brightness adjustment, but the display color may not be changed.
As an alternative embodiment, a hardware framework diagram of the electronic device in the present application may be as shown in fig. 2. As shown in fig. 2, the electronic device may include a light sensing unit, a display & touch module, a processor, a memory, and a transmission medium. Wherein the light sensing unit performs ambient brightness detection and provides input parameters for content brightness adjustment, such as ambient light brightness values, to the processor. The display & touch module can display content/receive touch information while communicating touch-aware input information to the processor, including the function of manually adjusting brightness. The memory is connected with the processor and executes necessary data caching in the operation process of screen projection of the system. The transmission medium optionally comprises a wireless data transmission medium and a wired data transmission medium, and the transmission medium is mainly used for transmitting screen projection contents to the display terminal in the screen projection process.
