Fig. 1 is a flowchart illustrating a method for adjusting screen brightness according to an embodiment of the present invention.
A method for adjusting screen brightness, a screen is arranged on a mobile terminal, the method comprises:
s1: acquiring the visual field direction of human eyes;
s2: acquiring the spatial position of human eyes;
s3: acquiring the visual field range of human eyes according to the visual field direction and the space position;
s4: acquiring the illumination intensity in the visual field range;
s5: and adjusting the brightness of the screen according to the illumination intensity.
In the invention, the mobile terminal can be an intelligent device such as a mobile phone, a tablet, an intelligent watch, a sports bracelet and the like.
In step S1, the visual field direction of the human eye can be represented by a ray, the starting point is the midpoint of the line between the two eyes of the user, and the starting point extends to the direction the user looks at.
In step S2, when the user uses the mobile terminal, the eyes are always located in front of the screen, and the spatial position of the eyes can be obtained by acquiring the linear distance between the eyes and the screen and combining the known visual field direction of the eyes.
In step S3, the visual field range of the human eye is a three-dimensional space formed by projecting the spatial position of the human eye as a starting point in the visual field direction of the human eye within a certain range. Thus, after determining the spatial position and the viewing direction of the human eye, the viewing range of the human eye can be determined. In this embodiment, the spatial position of the human eye is represented by the midpoint of the line between the two eyes.
The present embodiment limits the above-mentioned certain angle range. Specifically, referring to fig. 2, taking an example when human eyes are looking straight, a certain angle range of the present embodiment is defined as: the visual field angle of the human eyes on the vertical plane is-40 degrees to +30 degrees and the visual field angle of the human eyes on the horizontal plane is-30 degrees to +30 degrees by taking the visual field direction as a reference. Within this range of angles, the human eye has the ability to distinguish colors.
In step S4, the illumination intensity within the visual field of human eyes when the user uses the mobile terminal is collected. Specifically, generally, the illumination intensity in each direction centered on the mobile terminal can be acquired by a light sensor provided on the mobile terminal. According to the invention, on the basis of knowing the visual field range of human eyes, the specific direction of the visual field range of human eyes on the mobile terminal can be analyzed and obtained, the illumination intensity in the direction is obtained by using the optical sensor arranged on the mobile terminal, and the illumination intensity information in other directions obtained by the optical sensor is abandoned, so that the illumination intensity in the visual field range of human eyes can be obtained. In other embodiments, an environment forming environment image in the field of view can be captured by the rear camera, and then the brightness of the environment image is analyzed to obtain the illumination intensity in the field of view.
In step S5, the brightness of the screen is adjusted according to the collected illumination intensity. In one embodiment, the brightness of the screen is adjusted to be consistent with the collected illumination intensity; in other embodiments, a relational mapping table of screen brightness and illumination intensity is set according to a preset rule, each illumination intensity value can find a screen brightness value corresponding to each illumination intensity value in the relational mapping table, and then the brightness of the screen is adjusted to be consistent with the screen brightness value corresponding to the illumination intensity value according to the collected illumination intensity value. For example, in one embodiment, in order to allow the human eye to clearly see what is displayed on the screen, the screen brightness value is greater than the illumination intensity value, and the difference between the two varies with the magnitude of the illumination intensity value, the greater the difference. In other embodiments, the screen brightness value may be set in proportion to the illumination intensity value. The relationship between the screen brightness value and the illumination intensity value is not limited in the invention.
The embodiment provides a method for adjusting screen brightness, wherein the screen is a screen of a mobile terminal. According to the invention, the visual field range of human eyes is determined by acquiring the spatial position and the visual field direction of the human eyes of the user, and then the brightness of the screen of the mobile terminal is adjusted according to the acquired illumination intensity in the visual field range, so that the brightness of the screen is adaptive to the ambient illumination intensity in the visual field range of the human eyes, the screen brightness is prevented from being too high or too dark, the effect of accurately adjusting the screen brightness is achieved, and great effects are achieved in the aspects of preventing eye fatigue of the user, maintaining eye health of the user and improving user experience.
In an embodiment of the method for adjusting screen brightness, the step S1 of obtaining the visual field direction of human eyes includes:
s1.1: acquiring the screen orientation of a screen;
s1.2: acquiring the inclination direction of human eyes relative to a screen;
s1.3: and determining the visual field direction of human eyes according to the orientation and the inclination direction of the screen.
When a user uses the mobile terminal to carry out interaction, human eyes look at the screen, but the visual field direction of the human eyes is not necessarily perpendicular to the surface of the screen, and has a certain inclination angle with the screen, and the inclination angle can be changed at any time.
In step S1.1, the present embodiment first determines the screen orientation of the screen, where the screen orientation is set to be perpendicular to the front side of the screen.
In step S1.2, the direction of the inclination of the human eye with respect to the screen is expressed with reference to the screen orientation of the screen, which can be expressed by two angle values. Referring to fig. 3, a schematic diagram of a tilt direction of a human eye M with respect to a screen N is shown, wherein a rectangular coordinate system is established with a point on the screen N as an origin, a short side of the screen N as an X-axis, a long side as a Y-axis, and a direction perpendicular to the screen N as a Z-axis. The direction of the Z axis is the screen orientation of the screen N, and the inclination direction of the human eyes M relative to the screen N can be represented by a first inclination angle α and a second inclination angle β. The first inclination angle alpha is an included angle between a first human eye M 'of the human eye M mapped on the ZY plane and the screen orientation (Z axis), and the second inclination angle beta is an included angle between a second human eye M' of the human eye M mapped on the ZX plane and the screen orientation (Z axis). When the values of the first inclination angle α and the second inclination angle β are both 0, the visual field direction of the human eye is perpendicular to the screen, that is, the visual field direction of the human eye is just opposite to the screen orientation of the screen at the moment.
In step S1.3, the visual field direction of the human eye can be calculated by the acquired screen orientation of the screen and the inclination direction of the human eye relative to the screen.
In the method for adjusting screen brightness according to an embodiment of the present invention, the mobile terminal is provided with a gravity sensor and a direction sensor, and the step S1.1 of obtaining the screen orientation of the screen includes:
s1.1.1: acquiring a vertical turning angle of a screen through a gravity sensor;
s1.1.2: and acquiring the horizontal rotation angle of the screen through a direction sensor.
In the present embodiment, referring to fig. 4, the screen orientation of the screen of the mobile terminal may be represented by a vertical flip angle α 'and a horizontal rotation angle β' of the screen. Where c denotes a vertical plane in space, α 'denotes the vertical turning angle of the screen, and β' denotes the horizontal turning angle of the screen. After determining the vertical flip angle α 'and the horizontal rotation angle β', the screen orientation of the screen may be determined.
In step s1.1.1, the vertical flip angle α' of the screen is obtained by providing a gravity sensor in the mobile terminal. The gravity sensor arranged in the mobile terminal adopts an elastic sensitive element to manufacture a cantilever type displacer and an energy storage spring manufactured by the elastic sensitive element to drive an electric contact, so that the conversion from the gravity change to the electric signal is completed. Gravity sensors operate on the principle of the piezoelectric effect. The so-called piezoelectric effect is "the phenomenon that external force applied to the crystal for heteropolar crystals without symmetry centers changes the polarization state of the crystal in addition to deforming the crystal, and establishes an electric field inside the crystal, and the medium is polarized due to mechanical force action is called positive piezoelectric effect". The gravity sensor utilizes the characteristic that the crystal is deformed due to acceleration in the gravity sensor. Since this deformation generates a voltage, the acceleration can be converted into a voltage output by simply calculating the relationship between the generated voltage and the applied acceleration.
In step S1.1.2, a horizontal rotation angle β' of the screen is acquired by providing an orientation sensor in the mobile terminal. The direction sensor of the present embodiment may be a compass or a gyroscope.
In the method for adjusting the screen brightness according to an embodiment of the present invention, a front camera is disposed on the screen. Step S1.2 of obtaining the tilt direction of the human eyes with respect to the screen includes:
s1.2.1: shooting human eyes through a front camera to form a first image;
s1.2.2: acquiring an imaging position of a human eye in a first image;
s1.2.3: and calculating the inclination direction of the human eyes relative to the screen according to the imaging position.
In step s1.2.1, since the front-facing camera is disposed on the screen, the tilt direction of the human eye relative to the screen is substantially equal to the tilt direction of the human eye relative to the front-facing camera, and the tilt direction of the human eye relative to the screen can be analyzed and calculated according to the position of the human eye on the imaging plane of the front-facing camera. When the user uses the terminal, the visual field direction of human eyes is towards the screen, so that the front camera can capture the human eyes of the user. The front camera shoots human eyes to form a first image.
In step S1.2.2, since there are two eyes of the user, two eyes will appear in the first image, and the embodiment performs face recognition on the first image by using a face recognition technology, further determines the specific positions of the two eyes in the first image, and then determines the midpoint of the connecting line of the positions of the two eyes as the imaging position of the eyes in the first image.
In step S1.2.3, by analyzing the imaging position of the human eye in the first image, the tilt direction of the human eye relative to the screen, that is, the first tilt angle α and the second tilt angle β can be obtained by the AI algorithm.
Thus, in an embodiment of the invention, in step S1.3, the direction of the field of view of the human eyes is determined by the screen orientation of the screen and the direction of the inclination of the human eyes with respect to the screen. Specifically, the visual field direction of the human eye is determined as: the vertical inclination angle is alpha '-alpha and the horizontal inclination angle is beta' -beta relative to a vertically placed screen.
In the method for adjusting screen brightness according to an embodiment of the present invention, the step S2 of obtaining a spatial position of a human eye includes:
s2.1: acquiring the area ratio of human eyes in the first image;
s2.2: judging the distance between the human eyes and the screen according to the area ratio;
s2.3: and determining the space position of the human eyes according to the visual field direction and the distance.
In step S2.1, according to the imaging principle, the area ratio of the human eye in the imaging picture is smaller when the human eye is farther away from the camera, and the area ratio of the human eye in the imaging picture is larger when the human eye is closer to the camera. Therefore, in this embodiment, the face recognition is performed on the first image first, and then the area ratio of the two eyes in the first image is determined.
In step S2.2, the distance of the human eye from the screen can be calculated according to the area ratio of the human eye in the first image.
In step S2.3, the spatial position of the human eye may be determined from the distance between the human eye and the screen and the direction of the field of view of the human eye. And taking the front camera as an origin, and taking the position reached by moving the distance to the visual field direction of the human eyes as the space position of the human eyes.
In the method for adjusting the screen brightness of the embodiment of the invention, the mobile terminal is provided with a front camera and a rear camera; the visual field range comprises a first visual field range in front of the screen and a second visual field range behind the screen; the step S4 of acquiring the illumination intensity in the field of view includes:
s4.1: acquiring a first illumination intensity B1 in a first visual field range through the front camera;
s4.2: and acquiring a second illumination intensity B2 in a second visual field range through the rear camera.
In the present embodiment, the illumination intensity in the visual field range of the human eye includes a first illumination intensity B1 and a second illumination intensity B2.
In one embodiment of the invention, optical sensors are arranged on the front camera and the rear camera of the mobile terminal. Specifically, generally, the light intensity in each direction in front of the screen can be acquired by the light sensor provided on the front camera, and the light intensity in each direction behind the screen can be acquired by the light sensor provided on the rear camera. In the invention, on the basis of knowing the visual field range of human eyes, the specific position of the first visual field range in front of the screen and the specific position of the second visual field range in back of the screen can be analyzed and obtained, then the front camera is utilized to obtain the first illumination intensity of the first visual field range in the specific position in front of the screen and the second illumination intensity of the second visual field range in the specific position in back of the screen, and then the illumination intensity in the visual field range of human eyes can be obtained through a preset calculation rule.
Further, the step S5 of adjusting the brightness of the screen according to the illumination intensity includes:
s5.1: adding the first illumination intensity B1 and the second illumination intensity B2 according to a certain weight to obtain target brightness B;
s5.2: the brightness of the screen is adjusted to the target brightness B.
Specifically, B ═ η B1+ ξ B1. Wherein η + ξ ═ 1. In general, η ═ ξ ═ 0.5. The invention is not limited in this regard.
In the method for adjusting screen brightness according to another embodiment of the present invention, the method for adjusting screen brightness further includes:
s6: acquiring environmental colors in a visual field range;
s7: analyzing the tone attribute of the environment color;
s8: and adjusting the display tone of the screen according to the tone attribute of the environment color.
Specifically, the environmental color of the visual field can be classified into red, red orange, yellow orange, red violet, blue violet, blue-green, and the like. The hue attribute of ambient colors can be divided into warm and cool hues. Wherein, the hue attribute of warmer colors such as red, red orange, yellow orange, and red purple is warm hue, and the hue attribute of warmer colors such as blue, blue purple, and blue green is cool hue. And when the tone attribute of the ambient color is a cold tone, correspondingly adjusting the display tone of the screen to be a warm tone.
The method for adjusting the screen brightness can adjust the screen brightness according to the illumination intensity in the visual field range of human eyes, and can adjust the display tone of the screen according to the environment color in the visual field range, so that the display tone of the screen is adaptive to the environment color, the human eyes are further protected, and the experience of a user is improved.
Further, the mobile terminal comprises a rear camera;
the step S6 of acquiring the environmental color in the field of view includes:
s6.1: shooting through a rear camera to form a second image;
s6.2: acquiring a region of the visual field range of human eyes mapped in the second image;
s6.3: and judging the color in the area to be the environment color.
In step S6.1, when the user uses the mobile terminal, the visual field direction of the human eyes is oriented towards the screen, and therefore, the environmental object that can be captured by the rear camera of the mobile terminal certainly includes the environmental object within the visual field range of the human eyes. Therefore, the environment behind the mobile terminal is shot by the rear camera to form a second image.
In steps S6.2 and S6.3, the environmental objects present at least in some regions in the second image are environmental objects in the field of vision of the human eye. Therefore, after the visual field range of the human eyes is known, the area of the visual field range of the human eyes, which is mapped in the second image, can be captured through the relevant AI technology, and the picture color in the area is the environmental color in the visual field range of the human eyes.
Further, the step S7 of analyzing the hue property of the environment color includes:
s7.1: analyzing RGB three primary colors of the environment color;
s7.2: and judging the tone attribute of the environment color.
The RGB color scheme is a color standard in the industry, and various colors are obtained by changing three color channels of red (R), green (G) and blue (B) and superimposing the three color channels on each other, where RGB represents colors of the three channels of red, green and blue, and the color standard almost includes all colors that can be perceived by human vision, and is one of the most widely used color systems at present. The RGB color can be divided into 255 levels, 24-bit color is also used for identifying the environmental color, the photosensitive chip can collect relevant color information, and different colors can be obtained by RGB three colors according to different mixing ratios. For example, R (0) G (0) B (0) represents white, R (255) G (0) B (0) represents pure red, and R (0) G (0) B (0) represents black. Each of the ambient colors has a corresponding value in the range of R (0) G (0) B (0) -R (255) G (255) B (255).
In step S7.1, RGB analysis is performed on the environment color, and it can be determined which colors the environment color includes and the area ratio of each color in the above-mentioned region.
In step S7.2, the color attribute of the ambient color can be determined according to the color type and the area ratio in the acquired region. For example, if most colors in the region belong to warm colors, the color attribute of the environmental color is determined as warm tone, or alternatively, if a large area in the region is warm colors, the color attribute of the environmental color is determined as warm tone; otherwise, the color is judged to be cool.
Further, in step S8, if the color attribute of the ambient color is determined to be a warm tone, the display color tone of the screen is adjusted to be a warm tone, specifically, the color of the screen may be adjusted to be light orange; if the color attribute of the ambient color is judged to be a cool tone, the display tone of the screen is adjusted to be a cool tone, and specifically, the color of the screen may be adjusted to be light blue. The light orange and light blue are used for illustration, but the present invention is not limited thereto, and the user may set the color according to personal preference.
