Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
Referring to fig. 1, fig. 1 is a flowchart of a light supplement method for shooting according to an embodiment of the present invention, where the method provided in this embodiment can be applied to an electronic device, as shown in fig. 1, and includes the following steps:
The shooting preview interface can be obtained through a camera of the electronic device, the shooting preview interface is generally displayed on a display screen of the electronic device, and the camera and the display screen can be located on the same side.
Wherein, the preview image in the shooting preview interface can be gathered through the camera on the electronic equipment and obtained, and this camera can be the leading camera or the rear camera of electronic equipment, promptly: the preview image in the shooting preview interface can be an image acquired by a front camera or an image acquired by a rear camera.
It should be noted that the electronic device in the embodiment of the present invention may have a multi-surface display screen (when having two-surface screens, the electronic device may be referred to as a dual-surface screen electronic device), and each display screen may be configured with a corresponding camera.
And step 102, adjusting the display parameters of the light compensation layer.
The working principle of the embodiment of the invention can be expressed as follows:
the shooting preview interface comprises the light supplement layer, and the display parameters (such as transparency, brightness or display color and the like) of the light supplement layer are adjusted, so that the illumination intensity or color temperature of the light supplement layer irradiating the shooting object (the shooting object can be an object in the environment where the electronic equipment is located, for example, the shooting object can be located in the direction facing the screen on which the shooting preview interface is displayed) can be adjusted, the purpose of supplementing light for the shooting object is achieved, the brightness of the shooting object (such as a human face) in the preview image acquired by the electronic equipment through the camera can be adjusted, and the display effect of the preview image is enhanced. Note that the preview image may be an image displayed on the shooting preview interface, for example: the shooting preview interface comprises a preview layer, the light supplement layer can be displayed on the preview layer in an overlapped mode, and the preview image can be an image displayed on the preview layer.
It should be noted that the specific types of the finishing layer and the preview layer are not limited herein, for example: the light-compensating layer and the preview layer can be two layers respectively, or the light-compensating layer and the preview layer can be two windows respectively.
The principle of the light supplement layer for supplementing light to the shooting object can be described as follows:
when the shading layer is not arranged, the shooting preview interface usually displays a preview image, and when the brightness of the environment where the electronic equipment is located is dark (such as night without lighting), the preview image is usually a black image; after the light supplementing layer is added, the light supplementing layer can be white or other colors (generally not black), so that light emitted by the light supplementing layer can illuminate a shooting object (such as a face of a user), the display brightness of the shooting object in a preview image is enhanced, and the light supplementing layer completes light supplementing on the shooting object. Of course, the display colors of the light supplement layers are different, the light supplement effect on the shooting object is different, meanwhile, the transparency of the light supplement layers is different, and the light supplement effect on the shooting object is also different. In the embodiment of the invention, the adjustment of the light supplement effect of the shot object can be completed by adjusting the display parameters (such as transparency, color or display brightness) of the light supplement layer.
In addition, the light-compensating layer and the preview layer may be generated at the same time, or of course, the preview layer may be generated first and then the light-compensating layer may be generated. For example: referring to fig. 2, the electronic device displays a preview layer 201, and does not display a touch-up layer; referring to fig. 3, the electronic device displays a touch-up layer 202 on a preview layer 201, where the touch-up layer 202 is indicated by oblique lines in fig. 3.
In addition, as an optional implementation manner, the preview layer may also be displayed on the light supplement layer in a superimposed manner, so that the light supplement effect can be achieved, and meanwhile, the light supplement effect can be achieved on the preview image on the preview layer.
The specific type of the display parameter is not limited herein, and for example: the display parameters may include at least one of transparency, display color, and display brightness.
For example: when the display parameters include transparency, and when the display brightness of the external environment where the electronic device is currently located is low (lower than a brightness threshold, for example, the brightness threshold may be 500 nit), that is, the external environment may be considered as a dark environment, and the display brightness of the light supplement layer may be a fixed value, and only the transparency of the light supplement layer may be reduced (for example, the transparency may be reduced by 10%), so that the illumination intensity of the light supplement layer on the photographic object is enhanced, thereby enhancing the light supplement effect on the photographic object, and further causing the electronic device to obtain a preview image through the camera, where the brightness of the photographic object in the preview image is higher, thereby enhancing the display effect of the preview image. It should be noted that, while the transparency is turned down, the display brightness of the screen of the electronic device may also be increased, so that the light supplement effect on the photographic subject may be further enhanced.
The above implementation principles are illustrated by way of example: when the transparency of the light supplementing layer is low, the quantity of light rays irradiating the user through the light supplementing layer is small, namely most of the light rays supplementing the light rays of the user are the light rays on the light supplementing layer, when the transparency of the light supplementing layer is high, the light rays displaying the preview images on the preview layer can supplement the light rays of the user through the light supplementing layer, and the preview images on the preview layer are usually dark (the brightness of the external environment is dark), so that the light supplementing effect of the user is poor.
In addition, after the light supplement layer completes light supplement on the shooting object, the shooting object (for example, a person) can change the shooting posture according to the needs of the shooting image, and adjust the functions of beauty or filter and the like, so that the preview image acquired by the electronic equipment presents a better display effect.
Certainly, when the display brightness of the environment where the electronic device is located is higher (higher than the brightness threshold), that is, the environment where the electronic device is located may be regarded as a bright environment, at this time, when the electronic device acquires the preview image, light supplement is not needed, so that the transparency of the light supplement layer may be increased (for example, the transparency may be increased by 100%), so that the light supplement layer does not affect the normal display of the preview image.
It should be noted that the electronic device may adjust the display parameters of the light-compensating layer according to an input instruction of a user, for example: the input instruction may be a voice instruction, and certainly, may also be a touch instruction for a control on the shooting preview interface, and the specific type is not limited herein.
In addition, the electronic device may also automatically adjust the display parameters of the light-compensating layer according to the environmental parameters of the current external environment, for example: when the brightness of the external environment is high, the electronic device may increase the transparency of the light supplement layer according to the illumination intensity of the external environment (or may decrease the display brightness of the electronic device or may not adjust the display brightness of the electronic device); when the brightness of the external environment is low, the electronic equipment can lower the transparency of the light supplement layer according to the illumination intensity of the external environment, and meanwhile, the display brightness of the electronic equipment can be increased.
In addition, the electronic equipment can also adjust the color of the light supplementing layer, and the light supplementing effect on the shot object is different due to different color temperature values of light emitted by different colors, so that the light supplementing effect on the shot object can be enhanced by adjusting the display color of the light supplementing layer, and the display effect of the preview image acquired by the electronic equipment through the camera is further enhanced.
The display color of the light-compensating layer can be adjusted according to the color temperature value of the environment where the electronic device is located, for example: when the color temperature value of the environment is low, the display color of the light supplement layer can be automatically switched to yellow light, and the display color of the light supplement layer can be switched to white light under other conditions. Therefore, the display color of the light supplementing layer can be adjusted in a self-adaptive manner according to different color temperature values of the environment, and the light supplementing effect of the light supplementing layer on the shot object is enhanced.
In addition, as an optional implementation manner, the display color of the light supplement layer may be switched according to the brightness value of the environment, that is, when the environment of the electronic device is a bright environment, the display color of the light supplement layer may be adjusted to be a relatively cold color; when the environment of the electronic equipment is a dark environment, the display color of the light supplement layer can be adjusted to be a warmer color, so that the display color of the light supplement layer can be adjusted according to the difference between a bright environment and the dark environment, and the light supplement effect on the shot object can be further enhanced. The following examples illustrate:
when the illuminance (representing the luminous flux received by the surface of the shot body in unit area) is within the range of 0-300, the display color of the light compensation layer can be a warm color system color, so that light compensation is performed; the display color of the light supplementing layer can be a cold color system color within the range of 300-500, so that light supplementing is performed; if it is more than 500, the light-compensating layer is not displayed. The unit of illuminance is lux (lux). Meanwhile, the illuminance and the brightness value are different parameters for representing the lighting condition of the environment in which the electronic device is located.
In an embodiment of the present invention, the electronic Device may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
In the embodiment of the invention, the shooting light supplement method comprises the following steps: displaying a shooting preview interface, wherein the shooting preview interface comprises a light supplementing layer; and adjusting the display parameters of the light compensation layer. Therefore, the shooting preview interface comprises the light supplementing layer, and light of the light supplementing layer can be irradiated on the shot object, so that the display brightness of the shot object in the image acquired by the camera is enhanced, and the display effect of the image is further enhanced.
Referring to fig. 4, fig. 4 is a flowchart of a light supplement method for shooting according to an embodiment of the present invention. The main differences between this embodiment and the previous embodiment are: the electronic equipment can adjust the display parameters of the light compensation layer according to the acquired environmental parameters of the environment. As shown in fig. 4, the method comprises the following steps:
The shooting preview interface can be obtained through a camera of the electronic device, the shooting preview interface is generally displayed on a display screen of the electronic device, and the camera and the display screen can be located on the same side.
It should be noted that the electronic device in the embodiment of the present invention may have a multi-surface display screen (when having two-surface screens, the electronic device may be referred to as a dual-surface screen electronic device), and each display screen may be configured with a corresponding camera.
The electronic equipment can acquire the environmental parameters of the environment through components such as a camera or a light sensor.
Alternatively, when the environment parameter includes an environment brightness value, then the display parameter may include transparency; when the environmental parameter includes a color temperature value, then the display parameter may include a display color.
For example: when the environment parameter includes an environment brightness value, the transparency of the light-compensating layer may be adjusted according to the environment brightness value, for example: referring to fig. 5, a light supplement layer 501 after adjusting transparency; when the environmental parameter comprises a color temperature value, the color of the light supplement layer can be adjusted according to the color temperature value.
It should be noted that, when adjusting the color of the light-compensating layer, the display brightness of the electronic device (i.e., the screen) may be adjusted together, and of course, the display brightness of the electronic device may not be adjusted, and the specific manner is not limited herein.
Optionally, when the environment parameter includes an environment brightness value, the display parameter may also include a display color, that is, the display color of the light-compensating layer may be adjusted according to the environment brightness value of the environment in which the electronic device is currently located. When the current environment of the electronic equipment is a bright environment, the light supplement layer can display the light in a cold color, and meanwhile, the electronic equipment can be controlled to emit light by adopting a cold light source; when the current environment of electronic equipment is the dark environment, the light filling layer can show with warm colour partially, simultaneously, can also control electronic equipment and adopt warm light source to shine partially. Like this, the light filling effect to the shooting object of reinforcing that can be further, simultaneously, can also make to present different colour display, reinforcing display effect on the electronic equipment.
Optionally, in a case that the environment parameter includes an environment brightness value, the display parameter includes transparency;
the adjusting the display parameters of the light compensation layer based on the environmental parameters comprises:
calculating the target transparency based on the environment brightness value and a preset brightness threshold value;
and adjusting the transparency of the light supplement layer to be the target transparency.
The specific manner of calculating the target transparency based on the environment brightness value and the preset brightness threshold is not limited herein.
For example: as an optional implementation manner, the environmental brightness value and the brightness threshold may be compared, when the environmental brightness value is greater than the brightness threshold, it may be calculated that the target transparency is equal to the first transparency, and then the current transparency may be increased to the first transparency (which is greater than the preset transparency); when the ambient brightness value is less than the brightness threshold, it may be calculated that the target transparency is equal to the second transparency, and then the current transparency may be reduced to the second transparency (less than the preset transparency).
It should be noted that, the increasing amplitude and the decreasing amplitude are not limited herein, for example: the greater the magnitude of the increase or the lesser the magnitude of the decrease as the ambient brightness value is closer to the brightness threshold; the greater the difference between the ambient brightness value and the brightness threshold, the greater the magnitude of the increase or the magnitude of the decrease.
Of course, as another alternative embodiment, the target transparency may also be calculated according to the ratio of the ambient brightness value to the brightness threshold, for example: when the ratio of the environmental brightness value to the brightness threshold value is 1, the target transparency is 100%; when the ratio of the environmental brightness value to the brightness threshold value is 0.5, the target transparency is 50%; when the ratio of the ambient brightness value to the brightness threshold is 2, the target transparency is 200%.
In the embodiment of the invention, the target transparency is calculated through the environment brightness value and the brightness threshold, so that the calculation result of the target transparency has correlation with the environment brightness value, the target transparency can more accurately reflect the brightness condition of the environment where the electronic equipment is located, the light supplement result of the shot object is more accurate, and the light supplement effect is better.
As an optional implementation manner, the calculating the target transparency based on the environment brightness value and a preset brightness threshold includes:
calculating the target transparency according to a preset formula T which is AxL/YxB;
wherein T is the target transparency, A is a constant, L is the ambient brightness value, Y is the brightness threshold, and B is 100%.
The specific value range of a is not limited herein, and can be summarized according to experiments. The specific values may be different under different experimental conditions.
The specific value of the brightness threshold is not limited here, for example: the brightness threshold may be 500 nits, and it should be noted that the ambient brightness value or the brightness threshold may be nit (nit) in the whole text.
The ambient brightness value may also be referred to as a current ambient brightness, and the brightness threshold value may also be referred to as a brightness critical value.
For example: the brightness threshold is 500 nits, a dark environment is defined when the environmental brightness value is less than 500 nits, and a bright environment is defined when the environmental brightness value is greater than or equal to 500 nits.
When the environment brightness value is greater than or equal to 500 nits, the light compensation layer is in a bright environment, the target transparency of the light compensation layer can be adjusted to be 100% without light compensation, the light compensation layer is completely transparent, a user cannot see light compensation pictures, and the experience is not influenced. When the environmental brightness value is 0, the environment is in the darkest environment, and the target transparency is calculated to be 0, that is, the light supplement layer is completely opaque, and the light supplement is completely performed, it should be noted that when the target transparency is 0, the display brightness of the screen can be adjusted, and as an optional implementation manner, the display brightness of the screen can be adjusted to be the maximum value. Of course, as another alternative embodiment, the display brightness of the light-compensating layer may also be increased.
In the embodiment of the invention, the target transparency is calculated by the preset formula, so that the calculation mode of the target transparency is simpler and more convenient, and the calculation result is more accurate.
Optionally, after obtaining the environmental parameter of the environment in which the electronic device is located, the method further includes:
and adjusting the display brightness of the screen of the electronic equipment based on the environment parameter.
For example: when the environment parameter includes an environment brightness value, the display brightness of the screen may be increased after the transparency of the light compensation layer is decreased. In addition, when the environmental parameter includes a color temperature value, the display brightness of the screen can be improved similarly after the display color of the light compensation layer is changed from a cold color system to a warm color system according to the color temperature value.
Of course, the display brightness of the screen may also be turned down based on the environmental parameters.
In the embodiment of the invention, the display brightness of the screen can be adjusted, so that the illumination intensity irradiated on the shot object can be enhanced when the display brightness of the screen is increased, and the light supplement effect on the shot object is further enhanced.
Optionally, in a case that the environment parameter includes a color temperature value, the display parameter includes a display color; wherein the display color is associated with the color temperature value.
In this embodiment, since the color temperature values of the lights emitted by different colors are different, the light supplement effect on the photographic subject is also different, and thus, by adjusting the display color of the light supplement layer, the light supplement effect on the photographic subject can be enhanced, and the display effect of the preview image acquired by the electronic device through the camera is further enhanced. The display color of the light-compensating layer can be adjusted according to the color temperature value of the environment where the electronic device is located, for example: when the color temperature value of the environment is low, the display color of the light supplement layer can be automatically switched to yellow light, and the display color of the light supplement layer can be switched to white light under other conditions. Therefore, the display color of the light supplementing layer can be adjusted in a self-adaptive manner according to different color temperature values of the environment, and the light supplementing effect of the light supplementing layer on the shot object is enhanced.
In the embodiment of the present invention, through steps 401 to 403, since the electronic device can obtain the environmental parameters of the environment where the electronic device is located, and adjust the display parameters of the light compensation layer based on the environmental parameters, the electronic device can automatically adjust the display parameters of the light compensation layer, so that the intelligent degree of the electronic device can be enhanced, and the user experience can be further enhanced.
It should be noted that, after adjusting the display parameters of the light compensation layer, referring to fig. 6, after a preview image 601 is displayed on the shooting preview interface, the user may adjust the posture of the user, and the electronic device may acquire a target image, where the target image may be an image acquired by the light compensation layer from a shooting object (which may be the user) after completing light compensation, and may also be an image acquired by the user after completing the posture adjustment.
In addition, after the target image is acquired, the electronic device can continuously acquire the environmental parameters and continuously adjust the display parameters of the light compensation layer based on the environmental parameters.
Referring to fig. 7, fig. 7 is a flowchart of a light supplement method for shooting according to an embodiment of the present invention.

Each color indicator may represent a color, such as: the first color indicator 9012 may indicate yellow, the second color indicator 9013 may indicate light green, the third color indicator 9014 may indicate dark blue, and the fourth color indicator 9015 may indicate black.
Thus, the target color can be selected by moving the target sub-control to the area where the target color identifier is located, and the color of the light supplement layer can be switched to the target color.
In the embodiment of the invention, the target color is selected through the target sub-control and the color identifier, so that the diversity and the flexibility of the target color determination mode are improved.
Optionally, the preview interface further includes a preview layer, the light supplement layer is superimposed and displayed on the preview layer, and the light supplement layer includes a hollow area.
The hollow-out region may be a light filling layer region with a transparency greater than a preset threshold, see fig. 12, where fig. 12 includes a preview layer 1201 and a light filling layer 1202, where the light filling layer 1202 includes a hollow-out region 12022, and a preview image 12011 may be displayed on the preview layer 1201, and of course, the hollow-out region may also be a region where the light filling layer is not disposed, and a specific type is not limited herein.
