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 method for detecting a relative position according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
In this embodiment, the display screen for displaying the image of the first predetermined color may be a liquid crystal display screen, or may also be a display screen made of light emitting diodes. The displaying of the image of the first predetermined color may be controlling a preset area of a display screen of the terminal device to display the image of the first predetermined color. And the preset area may be any area on the display screen of the terminal device, such as the upper side, the lower side, the left side or the right side of the display screen, and the like. Of course, other positions on the display screen may be used besides these positions, and the embodiment of the present invention is not limited thereto. The first predetermined color may be red, blue or some other color, etc.
And 102, receiving the visible light penetrating from the display screen through the color recognition sensor, and acquiring light ray information of different color light rays in the visible light.
In this embodiment, the color recognition sensor receives visible light transmitted by the display screen, and the visible light may include light directly receiving external environment, light emitted by the display screen of the terminal device, light reflected by an obstacle, and the like. The light information may be an intensity value or a wavelength of the light, and may also include other information of the light, which is not limited in the embodiment of the present invention.
In this embodiment, the preset area may be some areas around the color recognition sensor, so that the color recognition sensor can better receive the light emitted from the preset area and the light reflected by the obstacle. When the preset area is disposed around the color recognition sensor, it may be an annular area, or may also be a rectangular frame-shaped area, and the like, and the embodiment of the present invention is not limited thereto.
In this embodiment, there may be a plurality of implementation manners for determining that the external object and the terminal device are in the close state or the far state according to the light ray information of the first predetermined color light ray and the light ray information of the second predetermined color light ray obtained by the color identification sensor. For example: determining that the external object is close to or far away from the terminal equipment according to the light intensity values of the first preset color light and the second preset color light; or it may be determined that the external object is in a close state or a far state with respect to the terminal device according to a relationship between the light intensity values of the first predetermined color light and the second predetermined color light, and so on. In addition, other parameters may be added to make a more accurate determination, and the embodiment of the present invention is not limited thereto.
In this embodiment, the overlapping range of the wavelengths of the first predetermined color light and the second predetermined color light is smaller than or equal to the preset wavelength range, so that the influence between the first predetermined color light and the second predetermined color light can be reduced, and thus, more accurate detection can be performed in the process of whether an object is approaching.
For better understanding of the whole process, reference may be made to fig. 2, where fig. 2 is a schematic structural diagram of a terminal device according to an embodiment of the present invention. As shown in fig. 2, fig. 2 includes an object 10 to be detected, a glass cover plate 11, a display screen 12, a light shielding foam 13 and a color recognition sensor 14, a preset area M on the display screen 12 is an annular area around the color recognition sensor 14, and the area can be self-illuminated by the display screen 12. The light emitted from the predetermined area M is indicated by an arrow in fig. 2, and the light reflected by the object 10 can be detected by the color recognition sensor 14. Therefore, the terminal equipment can determine that the external object is close to or far away from the terminal equipment according to the light ray information of the light rays with different colors.
In the prior art, a distance sensor needs to be arranged on a terminal device to detect a distance, and an ambient light sensor also needs to detect light, so that the cost of the terminal device is high. In the embodiment, only one color recognition sensor is needed to be arranged on the terminal device, so that the function of the distance sensor can be realized, and the color recognition sensor can also detect the ambient light, so that the distance sensor and the ambient light sensor are not needed to be arranged, and the cost is saved for the terminal device. Moreover, the color recognition sensor can be arranged below the display screen, and the screen occupation ratio of the terminal equipment can be improved.
In the embodiment of the present invention, the terminal 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.
The method for detecting the relative position displays an image with a first preset color; receiving the visible light transmitted from the display screen through the color recognition sensor, and acquiring light ray information of different color light rays in the visible light; and determining that an external object and the terminal equipment are in a close state or a far state according to the light ray information of the first preset color light ray and the light ray information of the second preset color light ray acquired by the color identification sensor, wherein the wavelength overlapping range of the first preset color light ray and the second preset color light ray is less than or equal to a preset wavelength range. Therefore, the function of the distance sensor can be realized through one color recognition sensor, and the color recognition sensor can also detect light, so that the functions of the distance sensor and the ambient light sensor can be completed through one color recognition sensor, and the cost of the terminal equipment is saved.
Referring to fig. 3, fig. 3 is a flowchart of a method for detecting a relative position according to an embodiment of the present invention. The main difference between this embodiment and the previous embodiment is that in the method, it is determined that the external object and the terminal device are in the close state or the far state according to the change value of the first light intensity value, the change value of the second light intensity value, and the ratio. As shown in fig. 3, the method comprises the following steps:
In this embodiment, the display screen for displaying the image of the first predetermined color may be a liquid crystal display screen, or may also be a display screen made of light emitting diodes. The displaying of the image of the first predetermined color may be controlling a preset area of a display screen of the terminal device to display the image of the first predetermined color. And the preset area may be any area on the display screen of the terminal device, such as the upper side, the lower side, the left side or the right side of the display screen, and the like. Of course, other positions on the display screen may be used besides these positions, and the embodiment of the present invention is not limited thereto. The first predetermined color may be red, blue or some other color, etc.
In this embodiment, the color recognition sensor receives visible light transmitted by the display screen, and the visible light may include light directly receiving external environment, light emitted by the display screen of the terminal device, light reflected by an obstacle, and the like. The light information includes light intensity values so that some judgment can be made according to the light intensity values. Of course, the light information may include some other information of the light besides the light intensity value, so as to perform more accurate determination, and the like, and the embodiment of the present invention is not limited thereto.
In this embodiment, the first light intensity value of the first predetermined color light is obtained, and the variation value of the first light intensity value is determined, so that subsequent determination can be performed according to the first light intensity value and the variation value of the first light intensity value.
In this embodiment, the second light intensity value of the second predetermined color light is obtained, and the variation value of the second light intensity value is determined, so that subsequent determination can be performed conveniently according to the second light intensity value and the variation value of the second light intensity value.
In this embodiment, a ratio of the first light intensity value to the second light intensity value is determined, so as to facilitate subsequent determination according to the ratio.
In this embodiment, the determining that the external object and the terminal device are in the close state or the far state according to the change value of the first light intensity value, the change value of the second light intensity value, and the ratio may be performed in various ways. For example: when the change value of the first light intensity value and the change value of the second light intensity value respectively represent that the first light intensity value is reduced and the second light intensity value is reduced, and the ratio is increased, determining that an external object is close to the terminal equipment; or, no matter how the first light intensity value and the second light intensity value change, as long as the ratio is within a range, it is determined that the external object is in a distant state from the terminal device.
In this embodiment, the overlapping range of the wavelengths of the first predetermined color light and the second predetermined color light is smaller than or equal to the preset wavelength range, so that the influence between the first predetermined color light and the second predetermined color light can be reduced, and more accurate judgment can be performed, thereby better determining that an external object and the terminal are in a close state or a far state.
Optionally, the determining that the external object and the terminal device are in the close state or the far state according to the variation value of the first light intensity value, the variation value of the second light intensity value, and the ratio includes:
determining that an external object is close to the terminal device under the condition that the change value of the first light intensity value and the change value of the second light intensity value respectively represent that the first light intensity value is reduced and the second light intensity value is reduced, the ratio is larger than a preset threshold value, and the change value of the first light intensity value is smaller than the change value of the second light intensity value;
and under the condition that the ratio is within a preset ratio range, determining that the external object is far away from the terminal equipment.
In this embodiment, when an object is close to the terminal device, that is, an external object is close to the terminal device, the first light intensity value and the second light intensity value are both reduced because the external object shields the light of the environment. However, since the preset area of the display screen displays the image with the first predetermined color, the light with the first predetermined color is reflected by an external object close to the terminal device, so that the first light intensity value has an extra increment, that is, the variation value of the first light intensity value is smaller than the variation value of the second light intensity value. At this time, when the ratio is greater than the preset threshold, it may be determined that the external object is in a close state with the terminal device.
In this embodiment, when the ambient light changes, the light information of the light detected by the color recognition sensor also changes. However, since the spectral components of the ambient light are varied and include the first predetermined color light and the second predetermined color light, the light intensity values of the first predetermined color light and the second predetermined color light may be increased or decreased simultaneously, but the ratio of the first light intensity value to the second light intensity value is substantially kept within a constant range, i.e., the predetermined ratio range. Therefore, when the ratio is within the preset ratio range, it can be determined that no external object is close to the terminal device, that is, it is determined that the external object and the terminal device are in a far state. Of course, when the first light intensity value is stable, it can also be determined that the environment is stable.
In this embodiment, it is determined that the external object and the terminal device are in the close state or the far state through the variation value of the first light intensity value, the variation value of the second light intensity value and the ratio, and the detection process is convenient. And the function of the distance sensor can be replaced by the color recognition sensor, so that the cost of the terminal equipment is saved.
Optionally, the preset wavelength range is 0.
In this embodiment, if the preset wavelength range is 0, it indicates that there is no overlapping range between the wavelengths of the first predetermined color light and the second predetermined color light, so that there is no interference between the first predetermined color light and the second predetermined color light, and the detection result is more accurate.
Optionally, the first predetermined color light is red light, and the second predetermined color light is blue light;
or, the first predetermined color light is blue light, and the second predetermined color light is red light.
In the present embodiment, a general color recognition sensor has three channels, R, G and B channels, respectively. The R channel is most sensitive to red light and least sensitive to blue light due to its respective spectral design; the B channel is most sensitive to blue light and least sensitive to red light. Each pixel of the display screen is divided into three sub-pixels of r, g and b, and the light-emitting spectrum of each pixel is also different. The spectra of the red and blue pixels are completely isolated, while the spectra of the R, g and B channels of the screen are similar to the spectral trends of R, G and B channels of the sensor, so that the R channel of the color recognition sensor is completely unaffected by the blue light of the screen, and the B channel of the color recognition sensor is completely unaffected by the red light of the screen.
Thus, according to the spectral design, light emitted by a red image in a preset area of the screen can be sensed by an R channel in the sensor, and a B channel is not influenced by the red image of the screen; or the light emitted by the blue image in the preset area of the screen can be sensed by the B channel in the sensor, and the R channel is not influenced by the blue image of the screen, so that the detection result is more accurate, and the misjudgment is reduced.
The method for detecting the relative position displays an image with a first preset color; receiving visible light penetrating from the display screen through the color recognition sensor, and acquiring light ray information of different color light rays in the visible light, wherein the light ray information comprises a light ray intensity value; acquiring a first light intensity value of the first preset color light acquired by the color identification sensor, and determining a change value of the first light intensity value; acquiring a second light intensity value of the second preset color light acquired by the color identification sensor, and determining a change value of the second light intensity value; determining a ratio of the first light intensity value to the second light intensity value; and determining that an external object and the terminal equipment are in a close state or a far state according to the change value of the first light intensity value, the change value of the second light intensity value and the ratio, wherein the wavelength overlapping range of the first preset color light and the second preset color light is smaller than or equal to a preset wavelength range. Therefore, the function of the distance sensor can be realized through one color recognition sensor, and the color recognition sensor can also detect light, so that the functions of the distance sensor and the ambient light sensor can be completed through one color recognition sensor, and the cost of the terminal equipment is saved.
