Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.
An embodiment of an optical compensation method comprises the following steps:
referring to fig. 2, the optical compensation method of the present invention includes the steps of:
first, step S1 is executed to detect the ambient light illuminance of the smart mirror.
Then, step S2 is performed to obtain the light transmittance of the preset frequency range. The light transmittance is the transmittance of light in a preset frequency range when the light passes through the back surface of the semi-transparent and semi-reflective mirror of the cosmetic mirror from the front surface.
Next, step S3 is executed to generate a compensation luminance parameter according to the ambient light illuminance and the light transmittance.
Then, step S4 is executed to control the light supplement light source to emit compensation light to the side where the front surface of the half mirror of the intelligent mirror is located, where the brightness parameter of the compensation light is a compensation brightness parameter, and the frequency of the compensation light is a preset frequency range.
In summary, in this embodiment, the light compensation method of the present invention can generate the fill-in luminance parameter that is positively correlated to the ambient illuminance of the intelligent mirror and the transmittance of the light in the preset frequency range when the light passes through the back surface from the front surface of the half mirror of the intelligent mirror, so as to control the fill-in light source to emit the compensation light with the luminance parameter as the fill-in luminance parameter and the frequency range as the preset frequency range to the side of the front surface of the half mirror, thereby making up the loss of the light in the preset frequency range when the reflected light of the ambient light from the face of the user enters the half mirror, and making the color temperature of the light seen by the eyes of the user more consistent with the color temperature of the light reflected by the actually and normally used total reflector, thereby improving the user experience.
Preferably, the intelligent mirror of the present embodiment may be an intelligent mirror with a display function, such as a makeup mirror or a cosmetic mirror.
In the above step S1, the ambient light illuminance of the cosmetic mirror may be detected by various means, such as by an illumination sensor disposed on the cosmetic mirror, for example, the ambient light illuminance detected by the illumination sensor may be 1000Lux (Lux) at this step.
In the step S2, the transmittance of the light in the preset frequency range passing through the back surface of the half mirror of the cosmetic mirror from the front surface thereof may be a fixed value set in advance, for example, the transmittance may be 50%, and optionally, the preset frequency range may be a visible light frequency range (380 to 750THz), or may be a certain frequency range (e.g., 400 to 600THz) within the visible light frequency range.
As shown in fig. 3, generating a compensation brightness parameter according to the ambient light illuminance and the light transmittance includes:
step S31, in a light emitting state of the light supplement light source, obtaining a luminance at a first preset position in a light emitting region of the light supplement light source, where the luminance is a luminance parameter of the light supplement light source when the luminance is an ambient luminance.
And step S32, generating a compensation brightness parameter according to the luminous brightness parameter and the light transmittance, wherein the compensation brightness parameter is positively correlated with the luminous brightness parameter and the transmittance.
As for step S31, fig. 4 is a schematic view of an application scenario for obtaining the light-emitting brightness parameter of the light supplement light source according to the embodiment of the present invention, as shown in fig. 4, the light supplement light source L1 may be placed in a darkroom in advance, the light supplement light source L1 is turned on, the illuminance sensor S1 is disposed at a first preset position in the light-emitting region Y1 of the light supplement light source L1, the light supplement light source L1 is controlled to emit light within a range of the given light-emitting brightness parameter at the brightness parameter, and a given illuminance range corresponding to the given light-emitting brightness parameter range detected by the illuminance sensor S1 is recorded to obtain the corresponding relationship between the illuminance and the light-emitting brightness parameter in advance, so as to conveniently obtain the light-emitting brightness parameter in step S31. Wherein, the given light-emitting brightness parameters in the given light-emitting brightness parameter range correspond to the given illuminances in the given illuminance range one by one.
It should be emphasized that, for the indoor, the light environment in the local area (the area where the cosmetic mirror and the face of the user are located) is generally uniform, and for the supplementary light source L1, after the supplementary light source L1 emits light, the difference between the light condition at the light emitting point and the light condition at the position of the face is large, so that in step S31, when the illuminance at the first position of the supplementary light source L1 is the ambient illuminance, the light emitting parameter of the supplementary light source L1 is obtained, which is beneficial to more accurately generating the compensation luminance parameter in step S32, and is beneficial to controlling the supplementary light source L1 to emit compensation light more consistent with the actual light loss in step S4.
Optionally, the distance from the first preset position to the light emitting point of the fill-in light source L1 may be set according to the distance from the cosmetic mirror to the human face in a general application scene, for example, the distance from the first preset position to the light emitting point of the fill-in light source may be 50 cm.
In addition, the type and the range of the given light-emitting luminance parameter can be set according to an actual use scenario, for example, the given light-emitting luminance parameter can be the luminous flux of the light supplement light source L1, the unit of the luminous flux is lm (lumen ), the range of the given luminosity parameter can be 25-100 lm, and the given illuminance corresponding to the range of the given luminosity parameter is 500-4000 Lux.
With the above-described step S32, in generating the compensation luminance parameter from the light emission luminance parameter and the light transmittance, the compensation luminance parameter may be determined according to a first preset formula, which is expressed as formula (1):
B＝X×F×a (1)
wherein, B is a compensation brightness parameter, X is an adjustment coefficient, F is a brightness parameter, a is a light transmittance, and the adjustment coefficient is any value between 0.5 and 2.
Specifically, when the compensation luminance parameter is generated according to the emission luminance parameter and the transmittance, the compensation luminance parameter may be generated according to a first preset formula, where the first preset formula may be: b is a compensation luminance parameter, X is an adjustment coefficient, F is a light emission luminance parameter, and a is a transmittance, and the adjustment coefficient may be any value between 0.5 and 2. For example, if the transmittance obtained in step S2 is 50%, the light emission luminance parameter obtained in step S31 is 1000Lux, and the selected adjustment coefficient is 1, then in step S32, the compensation luminance parameter calculated according to the first preset formula is 500 lm.
After the compensation brightness parameter is generated, and the preset frequency range obtained in step S2 is 380 to 750THz, the light supplement light source can be controlled to emit compensation light with a brightness parameter of 500lm and a frequency range of 380 to 750THz to the front side of the half mirror when the step S4 is executed.
In this embodiment, the light supplement light source L1 includes a light supplement component disposed around the half mirror on the intelligent mirror. As can be seen, the light supplement light source L1 of the present embodiment includes a light supplement component disposed around the half mirror on the cosmetic mirror.

For example, fig. 11 is a schematic diagram of a real-time image of the front side of the half mirror according to an embodiment of the present invention, as shown in fig. 11, the pixels of the real-time image M1 may be 50 × 50, and the control device may find a pixel region C1 where the face contour F1 is located from the real-time image M1 through a face recognition algorithm, and use the center position of the pixel region C1 as the face center of the user.
In this step, with continued reference to fig. 11, the control means may take the center position of the real-time image M1 as the real-time image center, and specify a real-time direction D1 from the real-time image center to the user's face center based on the center position of the real-time image M1 and the center position of the pixel region C1.

With continued reference to fig. 11, after determining the center position of the real-time image M1 to the center position of the pixel region C1, the real-time distance between the two positions may be counted, and optionally, the real-time distance may be the number of pixels before the two positions, and assuming that the counted number of pixels may be 25, the real-time distance may be determined to be 25 pixels, and when the given distance is 10 pixels, the real-time distance may exceed the given distance.
In step 2042B, when the real-time distance exceeds the given distance, the fill-in light source L1 is controlled to swing along the real-time direction, so that the real-time distance is smaller than the given distance.
With reference to fig. 11, when the real-time distance from the center of the real-time image M1 to the center of the pixel region C1 exceeds a given distance, it indicates that the face of the user and the light supplement component 14 disposed around the half mirror 13 are deviated from the face of the user to some extent, at this time, the control device may control the light supplement light source L1 to swing along the real-time direction D1, so that the center of the real-time image M1 on the front side of the half mirror 13 and the center of the pixel region C1 are gradually close to each other, and thus the light emitted by the light supplement light source L1 is more intensively irradiated on the face of the user, and the user experience is further improved.
It should be noted that, in fig. 11, only the pixel of the real-time image M1 is taken as an example, and the given distance is taken as 10 pixels, alternatively, the pixel of the real-time image may also be adaptively set according to actual needs, for example, the pixel of the real-time image may also be 1000 × 1000 or 5000 × 5000, and the given distance may be 200 pixels or 1000 pixels, which is not limited in the embodiment of the present invention.

In step 2042B, the control device can adjust the horizontal swing of the housing 23 by controlling the rotation of the first rotating device 19, so as to drive the light supplement light source (the light supplement light source can include the light supplement component 25 and/or a display screen arranged on the back of the half-transmitting half-reflecting mirror 24) to swing left and right, and the control device can also control the second rotating device 22 to rotate, so as to drive the light supplement light source to swing up and down, so as to realize that the light supplement light source emits the compensation light toward the position of the face of the user.
