Referring to fig. 1 and fig. 2 together, an embodiment of the present application provides a backlight control method S100 for a notebook computer 200, where the notebook computer 200 includes a keyboard 213.
The method S100 includes:
step S1, determining the color value of the environment light of the environment where the notebook computer is located;
in step S1, when the environment of the notebook computer is a bar, the source of the ambient light of the environment of the notebook computer may be a lighting lamp, an atmosphere lamp, etc. of the bar. When the environment of the notebook computer is a cinema, the source of the ambient light of the environment of the notebook computer may be a movie screen. When the environment of the notebook computer is outdoor, the source of the ambient light of the environment of the notebook computer may be the sun. The color of the ambient light, i.e. the color that the ambient light is projected on the notebook computer. The color value, i.e. the code representing the corresponding color in the notebook computer, is, for example, hexadecimal color code, # FFB6C1 represents light pink and # FFC0CB represents pink.
Step S2, controlling the backlight color of the keyboard according to the color value of the ambient light.
In step S2, the backlight color of the keyboard is controlled by the color value of the ambient light, and the backlight color of the keyboard can be adjusted to be the opposite color of the ambient light, so as to improve the contrast between the backlight and the ambient light, thereby facilitating the user to use the keyboard in the ambient light. For example, if the color represented by the color value of the ambient light is red, the backlight color of the keyboard is controlled to be cyan, and cyan is the reverse color of red. For another example, if the color represented by the color value of the ambient light is green, the backlight color of the keyboard is controlled to be purple, and purple is an opposite color of green.
The backlight selectable colors of the keypad may include red, yellow, blue, green, cyan, blue, violet, and the like. If the backlight selectable colors of the keyboard do not have the color opposite to the color of the ambient light, the backlight colors of the keyboard can be controlled to be presented as the colors close to the color opposite to the color of the selectable colors. For example, if the color of the ambient light is blue, the color of the blue phase inverse is orange, and the selectable backlight color of the keyboard does not include orange, the backlight of the keyboard is controlled to be yellow or red in the selectable backlight color, the yellow and the red are closer to orange, whether the orange color is reddish or yellowish is further determined, if the orange color is reddish, the backlight of the keyboard is controlled to be red, and if the yellow color is yellowish, the backlight of the keyboard is controlled to be yellow.
Compared with the prior art, in the backlight control method S100 provided in the embodiment of the present application, the backlight color of the keyboard can be adjusted to the opposite color of the ambient light by determining the color value of the ambient light of the environment where the notebook computer is located and controlling the backlight color of the keyboard according to the color value of the ambient light, so as to improve the contrast between the backlight and the ambient light, and facilitate a user to use the keyboard in the ambient light, thereby implementing a backlight control method for diversification of backlight display of the keyboard.
In some embodiments of the present application, the notebook computer 200 includes an audio/video input unit 212 and a display unit 216, the audio/video input unit 216 is disposed at the display unit 212, and the display unit 212 is rotatable with respect to the keyboard 213.
The display unit 212 may be a display screen.
The keypad 213 is within a visual field of the av input unit 212. The audio/video input unit 212 may be a camera.
Step S1, the determining the color value of the ambient light of the environment where the notebook computer is located includes: acquiring an image containing the keyboard image through the audio and video input unit; positioning the area of the keyboard image in the image; and determining the color value of the ambient light of the environment where the notebook computer is positioned according to the color value of the positioned image area.

In some embodiments of the present application, the calibration color chart 210 covers four corners of the keyboard 213, which facilitates identifying the boundary of the keyboard 213 image.
In some embodiments of the present application, the color of the color check card 210 is not black, and the color of the keyboard 213 is black.
The capturing the position of the checking color card image in the image comprises: the keyboard image and the check color card image are both in a preset area of the image, and the non-black image in the preset area of the image is identified so as to capture the position of the check color card image in the image.
Although the keyboard and the display unit can rotate relatively, the keyboard image is always within a preset area in the image no matter how far the keyboard rotates relative to the display unit, that is, the keyboard image is always within a general area range of the image. By setting the preset area, the capture range of the keyboard image and the check color card image in the image can be reduced, and the capture efficiency can be improved. The contrast between the keyboard and the backlight can be improved by setting the color of the keyboard to black, wherein, although the color of the keyboard is set to black, the keyboard inevitably has light reflection, and when the brightness value of the ambient light exceeds a threshold value, the color of the ambient light projected on the keyboard is basically the color of the ambient light, and the color of the backlight still needs to be adjusted to improve the contrast between the backlight and the ambient light. The position of the image of the color card in the image can be quickly and accurately captured and verified by identifying the non-black image in the preset area.
In some embodiments of the present application, the analyzing the color value of the located image area to determine the color value of the ambient light of the environment in which the notebook computer is located comprises: and determining the color value of the environment light of the environment where the notebook computer is located according to the color of the inspection color card image.

In some embodiments of the present application, the test color chip 210 is white in color.
In contrast to setting the check color card to be another color, after the ambient light is projected on the check color card, the original color of the ambient light is superimposed on the color of the check color card to form a superimposed color, for example, the color of the check color card is yellow, the original color of the ambient light is red, the superimposed color of yellow and red is orange, and by setting the color of the check color card to be white, the color presented by the projection of the ambient light on the check color card is the color of the ambient light, which does not need to be calculated by the superimposed color.
In some embodiments, the color chart 210 forms a plurality of color chart frames 2100 to divide the keyboard 213 into a plurality of keyboard 213 regions, each of the color chart frames 2100 covering a boundary of a corresponding one of the keyboard 213 regions.
Determining the color value of the ambient light of the environment where the notebook computer is located according to the color of the inspection color card image comprises determining the color value of the ambient light of a corresponding keyboard area according to the color of each color card frame image;
step S2, the controlling the backlight color of the keyboard according to the color value of the ambient light includes controlling the backlight color of a corresponding one of the keyboard regions according to the color value of the ambient light of each corresponding one of the keyboard regions.
The colors of different parts of the ambient light projected in different keyboard areas may be different, and the keyboard is divided into a plurality of keyboard areas, and the color value of the ambient light of the corresponding keyboard area is determined according to the color of the corresponding color card frame image so as to control the backlight color of the corresponding keyboard area, thereby further improving the contrast between the keyboard backlight and the ambient light.
In some embodiments, the calibration chart 210 is attached to the keyboard 213.

The sensing unit 214 may detect a current state of the notebook computer 200, such as an open/close state of the notebook computer 200, a position of the terminal, whether contact with a user, a direction of the terminal, or acceleration/deceleration of the notebook computer 200, to generate a sensing signal for controlling an operation of the terminal. In addition, whether the power supply unit supplies power or whether an external device is connected to the interface unit may be sensed. The sensing unit may include, for example, a touch sensor and a proximity sensor. The touch sensor is a sensor for detecting a touch operation. For example, the touch sensor may have the form of a touch film, a touch sheet, or a touch unit.
The touch sensor may have an interlayer structure (hereinafter, referred to as a "touch screen") together with the display unit. The touch sensor may be configured to convert a pressure applied to a specific portion of the display unit or a change in capacitance generated at the specific portion of the display unit into an electrical input signal. The touch sensor may be configured to detect not only a position and an area of a touch but also a pressure of the touch. When there is a touch input on the touch sensor, a signal (or signals) corresponding thereto is sent to the touch controller. The touch controller processes the signal(s) and then sends corresponding data to the controller. Thus, the controller may determine which region of the display unit is touched.
A proximity sensor refers to a sensor for detecting the presence of an object approaching a predetermined detection surface or existing in the vicinity using a force in an electromagnetic field or infrared light without mechanical contact. In addition, proximity sensors have a longer lifetime and higher utility than contact sensors.
Examples of the proximity sensor include a transmission type photosensor, a direct reflection type photosensor, a mirror reflection type photosensor, a high-frequency oscillation type proximity sensor, a capacitance type proximity sensor, a magnetic proximity sensor, and an infrared light proximity sensor. When the touch screen is capacitive, the touch screen is configured to detect the proximity of a pointer by a change in an electric field due to the proximity of the pointer. In this case, the touch screen (touch sensor) may be classified as a proximity sensor.
The proximity sensor detects a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement, etc.). Information corresponding to the detected proximity touch and the proximity touch pattern may be output on the touch screen.
The output unit 215 is used to generate an output related to a visual sense, an auditory sense, or a touch, and may include a sound output module, an alarm unit, and a haptic module.
The sound output module may output audio data received from the wireless communication unit or output audio data stored in the memory upon receiving a call signal in a call mode, a recording mode, a voice recognition mode, or a broadcast reception mode. The voice output module may output a voice signal (e.g., a voice of receiving a call signal, a voice of receiving a message, etc.) related to a certain function performed by the notebook computer 200. The sound output module may include a receiver, a speaker, or a buzzer.
The alarm unit outputs a signal for notifying the occurrence of an event of the terminal. Examples of events occurring in the notebook computer 200 include a call signal being received, a message being received, a key signal input, and a touch input. The alarm unit may output a signal other than a video signal or an audio signal, for example, a signal notifying occurrence of an event by vibration. The video signal or the audio signal may be output through the display unit or the sound output module. Thus, the display unit or the sound output module may be classified as a part of the alarm unit.
The haptic module generates various haptic effects that a user can feel. A typical example of a haptic effect generated by a haptic module is vibration. The intensity and pattern of the vibrations generated by the haptic module may be controlled. For example, different vibrations may be output synthetically or sequentially.
The haptic module may generate various haptic effects other than vibration, such as the effects of various stimuli: for example, an array of pins that move vertically with respect to the skin-contacting surface, air jet or suction through an orifice or suction hole, rubbing across the skin surface, contact of electrodes, or electrostatic forces and the use of elements that can absorb or release heat to reproduce the effects of cold and heat.
The haptic module can not only transmit a haptic effect by a direct touch but also implement a haptic effect by, for example, a muscle sense of a finger or an arm of a user. Two or more haptic modules may be provided according to the type of formation of the terminal.
The display unit 216 displays information processed by the notebook computer 900. For example, when the terminal is in a call mode, a User Interface (UI) or a Graphic User Interface (GUI) related to a call is displayed. When the terminal is in a video call mode or a photographing mode, photographed and/or received images, a UI or a GUI are displayed.
The display unit 216 may include at least one of a liquid crystal display unit (LCD), a thin film transistor liquid crystal display unit (TFT LCD), an organic light emitting diode display unit (OLED), a flexible display unit, and a three-dimensional (3D) display unit.
There may be two or more display units depending on the implementation form of the terminal. For example, in the terminal, the plurality of display units may be separately or integrally arranged on the surface, or respectively arranged on different surfaces.
The interface unit 217 performs a function of a path connecting all external devices to the terminal. The interface unit receives data from an external device, is supplied with power and transfers power to each element within the terminal, or transmits data within the terminal to the external device. For example, a wired/wireless headset port, an external charger port, a wired/wireless data port, a memory card port, a port for connecting to a device having an identification module, an audio input/output (I/O) port, a video input/output (I/O) port, and a headset port may be included in the interface unit.
The identification module is a chip storing various information for authenticating a user's access to the terminal, and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), and a Universal Subscriber Identity Module (USIM). A device having an identification module (hereinafter referred to as "identification device") may be manufactured in the form of a smart card. Thus, the identification device may be connected with the terminal via the port.
The interface unit may be used as a path for supplying power from the cradle to the terminal when the terminal is connected to an external cradle, or a path for transmitting various command signals input by a user through the cradle to the notebook computer. Various command signals or power input from the cradle may be used as a signal for identifying whether the terminal is properly mounted to the cradle.
The memory 218 may store programs for operating the controller and may temporarily store input/output data (e.g., address book, messages, still images, video, etc.). The memory may also store data related to various patterns of vibration and sound output when a touch input is applied to the touch screen.
The memory 218 may include at least one of the following types of storage media: flash memory type memory, hard disk type memory, micro multimedia card type memory, card type memory (e.g., SD or XD memory), Random Access Memory (RAM), Static Random Access Memory (SRAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), Programmable Read Only Memory (PROM), magnetic memory, magnetic disk, and optical disk.
