In this embodiment, the brightness adjusting method of the mirror is applied to a mirror, the mounting shell is provided with a mounting space and a mounting opening communicated with the mounting space, the lens covers the mounting opening, and the LED lamp is arranged around the mounting opening; the circuit board is arranged in the mounting space, and the acquisition device is arranged on the surface of the mounting shell; the collecting device is electrically connected with the circuit board, and the LED lamp is electrically connected with the circuit board.
The brightness adjusting method of the mirror comprises the following steps:
step S1, controlling the acquisition device to acquire environmental parameters;
the acquisition device is used for acquiring surrounding environment parameters, such as brightness parameters, color parameters and the like. The acquisition device may be composed of a single sensor or may be composed of a plurality of sensors, such as a brightness sensor, a color sensor, and the like. When the LED lamp of the mirror is powered on, the display brightness of the LED lamp of the mirror is displayed when the LED lamp is powered off for the last time, meanwhile, the acquisition device acquires the environmental parameters in real time and transmits the acquired environmental parameters to the circuit board of the mirror so as to be analyzed and processed by the processor in the circuit board.
Step S2, determining a first adjusting voltage according to the environmental parameter, and adjusting the display brightness of the LED lamp according to the first adjusting voltage;
the first adjusting voltage is used for being output to the LED lamp so as to adjust the brightness of the LED lamp. The processor analyzes and processes the received environment parameters and generates first adjusting voltage corresponding to the received environment parameters, for example, the value of the color parameter in the environment parameters is obtained, and then the first adjusting voltage corresponding to the value of the color parameter is determined according to the corresponding relation between the value of the color parameter and the first adjusting voltage; or acquiring the value of the brightness parameter in the environmental parameter, and determining the first adjusting voltage corresponding to the value of the brightness parameter according to the corresponding relation between the value of the brightness parameter and the first adjusting voltage. The circuit board outputs the first adjusting voltage to the LED lamp so as to adjust the display brightness of the LED lamp. The processor can generate the corresponding first regulating voltage by changing the duty ratio of the output pulse signal.
Specifically, in an embodiment, step S2 includes:
step S21, determining a voltage regulation gear corresponding to the environmental parameter;
in this embodiment, a plurality of voltage adjustment gears are set in the circuit in advance, and if the voltage adjustment gears are different, the voltages output to the LED lamp are different, for example, the voltage adjustment gears are divided into a high gear, a medium gear, and a low gear; if the voltage regulating gear is high, the voltage output to the LED lamp is 5V; if the voltage adjusting gear is a middle gear, the voltage output to the LED lamp is 4.5V; if the voltage adjusting gear is low, the voltage output to the LED lamp is 4V, and the like. And after the environmental parameters are obtained, determining the corresponding voltage regulating gear according to the environmental parameters. For example, taking an environmental parameter as an example of the brightness parameter, storing a corresponding relationship between the brightness parameter and the voltage adjustment gear in a storage device of the circuit board in advance, extracting the brightness parameter from the environmental parameter after obtaining the environmental parameter, calculating a value of the brightness parameter, and determining the voltage adjustment gear corresponding to the brightness parameter of the environmental parameter according to the corresponding relationship between the value of the brightness parameter and the voltage adjustment gear.
Specifically, step S21 includes:
step S211, determining a preset brightness range in which the brightness parameter value of the environment parameter is located;
in this embodiment, after obtaining the environmental parameter, the brightness parameter in the environmental parameter is extracted, and a preset brightness range in which the value of the extracted brightness parameter is located is determined, where the preset brightness range may be preset and stored in the storage device.
Step S212, according to the corresponding relation between the preset brightness range and the voltage adjusting gear, determining the voltage adjusting gear corresponding to the preset brightness range.
And after the preset brightness range in which the extracted brightness parameter value is positioned is determined, determining a voltage regulating gear corresponding to the preset brightness range according to the corresponding relation between the preset brightness range and the voltage regulating gear. For example, if the preset brightness range is a to B, the voltage regulation gear is high, if the preset brightness range is B to C, the voltage regulation gear is medium, and if the preset brightness range is C to D, the voltage regulation gear is low.
And step S22, controlling the circuit board to generate a first regulating voltage corresponding to the voltage regulating gear.
After the voltage regulating gear is determined, a first regulating voltage corresponding to the voltage regulating gear is determined according to the corresponding relation between the voltage regulating gear and the first regulating voltage. For example, if the voltage adjustment gear is high, the first adjustment voltage output to the LED lamp is 5V; if the voltage adjusting gear is a middle gear, the first adjusting voltage output to the LED lamp is 4.5V; if the voltage adjustment gear is low, the first adjustment voltage output to the LED lamp is 4V, and the like.
Step S3, after the LED lamp displays according to the display brightness corresponding to the first adjusting voltage, collecting the image information displayed by the lens;
in this embodiment, can be at indoor installation image acquisition device, for example camera, and image acquisition device can be connected with the circuit board communication through communication module, for example 4G module, WIFI module or bluetooth module etc.. After the LED lamp displays with the display brightness corresponding to the first adjusting voltage, the processor further controls the image acquisition device to acquire the image information displayed in the lens, namely controls the camera or the camera to shoot the image currently displayed in the lens, and acquires the image information acquired by the image acquisition device. By collecting the image information displayed in the lens, whether the user state displayed in the lens is the best display state after the brightness of the LED lamp is adjusted is judged, namely, whether the overall effect of the user in the mirror, such as skin color, brightness and the like, is the best display state after the brightness of the LED lamp is adjusted is judged.
And step S4, determining a second adjusting voltage according to the image information, and adjusting the display brightness of the LED lamp according to the second adjusting voltage.
After the image information acquired by the image acquisition device is obtained, the processor determines a second adjustment voltage according to the acquired image information, for example, the gray value of the image is calculated according to the acquired image information, then the second adjustment voltage is determined according to the gray value of the image, and then the brightness of the LED lamp is adjusted again according to the second adjustment voltage, so that the brightness of the LED lamp is closest to the actual requirement of a user, and the user looks into a mirror at the brightness, so that the display effect is optimal.
Optionally, in an embodiment, step S4 includes:
step S41, obtaining preset feature information from the image information, and determining a second adjustment voltage according to the preset feature information.
The preset feature information may be face feature information of a user in the image information, wearing feature information of the user, and may also be environmental feature information around the user. In this embodiment, the preset feature information may be obtained from the image information according to actual needs, and the second adjustment voltage may be determined according to the obtained preset feature information. For example, if the mirror is mainly used for making up by a user, the preset feature information may be face feature information in an image, and the second adjustment voltage is determined according to the face feature information, so that after the LED lamp is displayed at the display brightness corresponding to the second adjustment voltage, the making-up effect of the user in the mirror is optimal.
Optionally, in an embodiment, referring to fig. 3, step S41 includes:
step S411, obtaining face feature information and wearing feature information of a user from the image information;
in this embodiment, the preset feature information is face feature information of a user in the image and wearing feature information of the user. After the image information acquired by the image acquisition device is obtained, the face characteristic information and the wearing characteristic information of the user are extracted from the image.
Step S412, calculating the gray value of the face feature information and the gray value of the wearing feature information;
the gray value refers to the color depth of a pixel point in an image, namely the RGB value of the image, and each pixel point of the image has a corresponding RGB value. In this embodiment, after the image information acquired by the image acquisition device is obtained, a part of the image about the facial features of the user and a part of the image about the wearing features of the user in the image are determined, and then the average gray value of the part of the image about the facial features of the user and the average gray value of the part of the image about the wearing features of the user are calculated. Specifically, the RGB values of each pixel point in the partial image of the user face feature may be calculated first, then the calculated RGB values of each pixel point are accumulated to obtain the total RGB value of the partial image of the user face feature, and then the ratio between the total RGB value and the total number of pixels of the partial image of the user face feature is calculated to obtain the average gray value of the partial image of the user face feature. The average gray value of the portion of the image of the user wearing feature in the image is calculated in the same manner.
Step S413, calculating a gray value of the image information according to the gray value of the face feature information and the gray value of the wearing feature information;
after obtaining the average gray value of the part of the image related to the human face feature and the average gray value of the part of the image related to the wearing feature of the user in the image, calculating the gray value of the whole image according to the average gray value of the human face feature and the average gray value of the wearing feature, for example, taking 70% of the average gray value of the human face feature and 30% of the average gray value of the wearing feature to be added as the gray value of the image; or, taking the sum of 50% of the average gray value of the human face features and 50% of the average gray value of the wearing features as the gray value of the image, wherein the gray value can be set according to actual needs. In other embodiments, the RGB values of each pixel point in the acquired image may be calculated, the RGB values of each pixel point are added to obtain a total RGB value, and then the ratio of the total RGB value to the total number of pixels is calculated to obtain the gray value of the image information. The gray value of the image is calculated according to the gray value of the part of the image with the human face characteristics and the gray value of the part of the image with the wearing characteristics in the image information, and the brightness of the LED lamp is adjusted according to the gray value, so that the user looks like the mirror under the brightness, the makeup and wearing effects of the user are best seen, and the display brightness of the mirror is most close to the real requirements of the user.
Step S414, determining a second adjustment voltage according to the gray-level value of the image information.
After the gray value of the image information is obtained, the second regulating voltage is determined according to the gray value of the image.
Specifically, step S414 includes:
step S4141 performs a difference calculation on the gray value of the image information and a reference gray value to obtain a gray difference value;
the reference gray value is an ideal gray value of the image. After the gray value of the acquired image is obtained, the gray difference value between the gray value of the image and the ideal gray value is further calculated, so that a second adjusting voltage is determined according to the gray difference value, and the display brightness of the LED lamp is adjusted again through the second adjusting voltage, so that the display brightness of the LED lamp is closest to the real requirement of a user.
And step S4142, controlling the circuit board to generate a second regulating voltage corresponding to the gray difference value.
After obtaining the gray scale difference value, calculating a second adjustment voltage according to the gray scale difference value, for example, the second adjustment voltage corresponding to the gray scale difference value may be determined according to a correspondence relationship between the gray scale difference value and the second adjustment voltage; or, determining a preset gray scale range in which the gray scale difference value is located, and then determining a second adjusting voltage corresponding to the gray scale difference value according to the corresponding relation between the preset gray scale range and the second adjusting voltage.
According to the technical scheme of the embodiment, the first adjusting voltage is determined according to the environmental parameters, so that the brightness of the LED lamp is adjusted according to the first adjusting voltage, then the image information displayed in the lens under the display brightness is collected, the second adjusting voltage is determined according to the image information displayed in the lens, the display brightness of the LED lamp is adjusted again, the display brightness of the LED lamp is enabled to be closest to the real requirement of a user, the user looks into the mirror under the display brightness, and the overall effect of dressing and wearing is optimal.
In one implementation, referring to fig. 4, after step S3, the method further includes:
step S31, judging whether the image information contains the face feature information of the user;
after the LED lamp displays the image information by the first adjusting voltage, the image information displayed by the lens is obtained, and the processor further judges whether the collected image information contains human face characteristic information, namely whether a user looks into the mirror is judged.
Step S32, when the image information contains the face feature information of the user, determining a second regulating voltage according to the image information is executed;
the processor performs the step of determining a second adjustment voltage based on the image information when a user is looking into the mirror.
And step S33, when the image information does not contain the face feature information of the user, reducing the display brightness of the LED lamp.
When the image information does not contain the face feature information of the user, namely when no user uses the mirror, the processor outputs a control signal, for example, the duty ratio of the pulse signal is reduced to reduce the brightness of the LED lamp, or the LED lamp is turned off, so that the purpose of saving power consumption is achieved.
In this embodiment, after the display brightness of the LED lamp is adjusted according to the ambient brightness, the processor controls the image acquisition device to acquire image information displayed in the lens at this time, so as to determine whether a user is looking into the mirror currently, and if no user is looking into the mirror currently, the processor controls the LED lamp to display at a lower brightness, so as to achieve the purpose of saving power consumption.
