Description

Technical Field

[0001] The present disclosure relates to the field of mobile terminal technology, and in particular to a method and device for adjusting screen color temperature, an electronic device, and a computer-readable storage medium. Background Art

[0002] With the development of smart terminal devices, more and more people are using smart terminal devices, and terminal devices play an increasingly important role in people's lives. Watching videos, reading e-books, browsing web pages, playing electronic games, etc. are inseparable from the operation of the terminal device screen. The terminal device can be a mobile phone, tablet computer, etc. For users who often use terminal devices for entertainment activities, the brightness and color temperature of the terminal display screen have the most direct impact on users.

[0003] Color temperature is a temperature measurement method. The concept of color temperature is based on a fictitious black object that emits different colors of light when heated to different temperatures, and the object appears in different colors. Different color temperatures also directly affect human physiology and psychology. For example, high color temperature can improve attention and is suitable for reading and working; low color temperature with a yellowish tint gives people a warm and soft feeling, which can soothe the mood and is suitable for relaxation. In the display, the higher the color temperature value, the bluer the color is, which belongs to the cold tone, while the lower the color temperature value, the redder the color is, which belongs to the warm tone. In the display process of terminal equipment, color temperature is a very important factor. A comfortable color temperature can make the screen consistent with the surrounding environment, so that users can effectively reduce visual fatigue during use, and fit the real color of the image, bringing a better viewing experience. Therefore, users need to adjust the color temperature of the screen during use.

[0004] At present, the screen color temperature of terminal devices is usually adjusted manually by users or by setting a specific time. When the mobile terminal is in multiple different environmental conditions in a short period of time, the screen color temperature cannot be adjusted in time, thereby reducing the visual experience of the mobile terminal.

[0036] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0037] When the characteristics of light in the external environment change, users will have different feelings about the color temperature of the screen. For example, when the screen color temperature is cold, users will feel more glare in a dark environment at night than in an environment with strong sunlight. Therefore, in order to meet the actual needs of users, it is necessary to obtain light information in different environments as a reference for adjusting the screen color temperature.

[0038] In some current technologies, the color temperature of some terminal devices still needs to be adjusted manually. This solution is simple and unintelligent. It only adjusts the color temperature in different time periods and cannot interact with the surrounding environment. Some terminals use color temperature sensors to sense the color temperature of ambient light. However, when the color temperature sensor is used as the basis for adjusting the color temperature of the screen, the color temperature value often jumps due to sensor defects and abnormal fluctuations in the ambient color temperature during the use of scene changes, affecting the user's visual experience. The color temperature sensor is often set in one direction of the terminal device, such as the back of the mobile phone. It is easily affected by special lighting conditions such as strong light and shadows in a single direction, resulting in a deviation between the obtained ambient color temperature value and the actual environment, and the screen is adjusted to an inappropriate color temperature, causing users to feel obvious discomfort when watching.

[0039] In order to solve the above problems, the present invention provides a screen color temperature adjustment method 10. Figure 1 The screen color temperature adjustment method 10 is applied to a terminal device, the terminal device includes a screen and a color temperature sensor, and the screen color temperature adjustment method 10 includes steps S11 to S13, which are described in detail below:

[0040] Step S11, determining color temperature data through a color temperature sensor.

[0041] When the terminal device is in the screen-on state, the ambient light of the current environment is obtained through the color temperature sensor, and the color temperature data is obtained according to the ambient light value; wherein the color temperature sensor can be an infrared-based color temperature sensor or other sensor that can measure color temperature, and the present disclosure does not limit this. After receiving the ambient light, the color temperature sensor performs spectroscopic processing on the ambient light to obtain the infrared ratio of the ambient light; and calculates the ambient color temperature value of the ambient light according to the infrared ratio.

[0042] In one embodiment, the terminal device includes multiple color temperature sensors respectively arranged in different directions; determining color temperature data through the color temperature sensors includes: obtaining sub-color temperature data of corresponding directions through the multiple color temperature sensors respectively; and determining the color temperature data based on all the sub-color temperature data.

[0043] By setting up multiple color temperature sensors, we can avoid the problem that when using a single sensor, the collected ambient color temperature data is not accurate enough and cannot reflect the overall color temperature due to sensor defects and large changes in ambient color temperature in the same scene. This helps to quickly collect color temperature data in multiple directions, making the color temperature data closer to the current real environment.

[0044] Among them, the color temperature sensor can be set on the back and front of the terminal device, and collect sub-color temperature data in the corresponding direction at the same time. After obtaining all the sub-color temperature data, the color temperature data in different directions are weighted, and the color temperature data on the back of the device has a higher weight. The user's line of sight when watching the screen is consistent with the environmental direction of the color temperature sensor on the back. When calculating the overall color temperature data, the color temperature data on the back is given priority, and combined with the color temperature data on the front, a more reasonable ambient color temperature value can be obtained.

[0045] Step S12, determining color temperature adjustment data based on the color temperature data and according to the ambient color temperature reference range, wherein the color temperature adjustment data is within the ambient color temperature reference range.

[0046] In the process of adjusting the color temperature, especially when the color temperature in the current environment is very different, the color temperature data is prone to change in the same scene due to different screen orientations. When the screen color temperature changes significantly, it will cause discomfort to the user when watching the screen. In order to avoid color temperature fluctuations, the present disclosure sets an ambient color temperature reference range, maps the range with the collected real-time color temperature data, and ensures that all values ​​of the changes caused by the color temperature data in the same environment can be mapped within the current ambient color temperature reference range, so that the color temperature adjustment in the current scene is more gentle and meets the user's eye needs.

[0047] Step S13, adjusting the color temperature of the screen based on the color temperature adjustment data.

[0048] Among them, the color temperature data can be mapped to the color temperature adjustment data through calculation. There is a preset correspondence between different color temperature data and different color temperature parameters, which is realized through mapping calculation. For example, the stronger the current color temperature, the lower the corresponding warmth level of the light environment, and the lower the corresponding color tone adjustment data, while the higher the current color temperature, the higher the corresponding warmth level of the dark environment, and the higher the corresponding color tone adjustment data.

[0049] like Figure 2 As shown, the present disclosure also provides another screen color temperature adjustment method 20, see Figure 3The screen color temperature adjustment method 20 is applied to a terminal device. The terminal device includes a screen and a color temperature sensor, and also includes an acceleration sensor. The screen color temperature adjustment method 20 includes steps S21 to S24, which are described in detail below:

[0050] Step S21, determining color temperature data through a color temperature sensor.

[0051] As described in the above embodiment, when the terminal device is in the screen-on state, the ambient light of the current environment is obtained through the color temperature sensor, and the color temperature data is obtained according to the ambient light value;

[0052] Step S22: Acquire the ambient color temperature reference range through the acceleration sensor and the color temperature sensor.

[0053] The accelerometer can measure the acceleration caused by gravity and calculate the tilt angle of the device relative to the horizontal plane. The accelerometer can sense the current direction of movement of the device, making it easier to collect different orientation information of the device when picking up or moving the device.

[0054] In one embodiment, if Figure 3 As shown, in step S22, obtaining the ambient color temperature reference range through the acceleration sensor and the color temperature sensor includes: step S221, confirming multiple orientations of the terminal device through the acceleration sensor, and obtaining the first color temperature data corresponding to each orientation through the color temperature sensor; step S222, determining the ambient color temperature reference range based on all the first color temperature data.

[0055] The scene change or use process is often accompanied by the movement of the device, and the acceleration sensor can monitor the direction of the device's movement. Combined with the color temperature sensor, it can record the color temperature data in the current direction. The combination of the acceleration sensor and the color temperature sensor can effectively obtain multi-directional data and obtain the overall color temperature data in the current environment that is closer to the real light. The multi-directional ambient color temperature data can be used to obtain a reasonable ambient color temperature reference range, avoiding data collection deviations caused by abnormal color temperature in a single direction.

[0056] In one embodiment, in step S222, the ambient color temperature reference range is determined based on all the first color temperature data, including: determining the upper limit of the ambient color temperature reference range based on the maximum value of all the first color temperature data; and determining the lower limit of the ambient color temperature reference range based on the upper limit. Usually, the maximum value of the data in the ambient color temperature can better reflect the current color temperature environment, and it is set as the upper limit. According to the preset range, the lower limit of the ambient color temperature is set so that the ambient color temperature has a reasonable and accurate range. When an abnormal color temperature change is detected, the corresponding data is mapped to the value in the ambient color temperature reference range, and the color temperature data is adjusted based on the mapped value.

[0057] In one embodiment, determining the ambient color temperature reference range according to all the first color temperature data in step S222 includes: recording user preference settings and obtaining user preference data; and determining the ambient color temperature reference range according to all the first color temperature data and the user preference data.

[0058] During the color temperature adjustment process, due to the preferences of some users, the screen color temperature will be manually adjusted according to their own perceptions. The corresponding environmental data will be recorded during each adjustment process. When the current environment is close to the environment when the user adjusted, the ambient color temperature reference range will be set based on the current environmental data and user preference data. This is more in line with the user's usage habits, avoids multiple manual adjustments during user use, and improves the user experience.

[0059] In one embodiment, if Figure 4 As shown, step S22 also includes: step S223 obtaining the current location area; step S224 if the current location area is indoors, obtaining the ambient color temperature reference range of the current location area through the acceleration sensor and the color temperature sensor.

[0060] When a user uses a terminal device indoors, the use environment is relatively stable and the use time is longer than that in an outdoor environment. Therefore, in this embodiment, when it is detected that the current location area is indoors, the color temperature is adjusted by combining an acceleration sensor and a color temperature sensor. On the one hand, when the device is outdoors, the outdoor lighting conditions are relatively stable, the light intensity is easier to detect, and the ambient color temperature value does not change significantly. On the other hand, when the user is outdoors, frequent scene switching and movement may occur, which will cause the acceleration sensor to continue working and consume more power. Therefore, in this embodiment, only when it is detected that the current location area is indoors, the ambient color temperature reference range of the current location area is obtained.

[0061] In one embodiment, the current location area is obtained in step S223, and further includes: confirming the current location area through a positioning system and / or an acceleration sensor of the terminal device. The location area can be obtained by using a positioning system to determine whether the current user is indoors, or by determining whether the acceleration sensor is in continuous motion to determine whether the user is outdoors. The present disclosure is not limited to this method for obtaining the location area.

[0062] Step S23, determining color temperature adjustment data based on the color temperature data and according to the ambient color temperature reference range, wherein the color temperature adjustment data is within the ambient color temperature reference range.

[0063] By setting the ambient color temperature reference range, the range is mapped with the collected real-time color temperature data to ensure that all values ​​of the changes caused by the color temperature data in the same environment can be mapped within the current ambient color temperature reference range.

[0064] Step S24, adjusting the color temperature of the screen based on the color temperature adjustment data

[0065] The color temperature adjustment data is obtained according to the environment, and the color temperature value of the terminal device's screen is adjusted, which improves the flexibility and accuracy of determining the ambient color temperature value, enhances the user's viewing experience and the true color restoration of the terminal device's images.

[0066] In one embodiment, the method further includes: setting an adjustment threshold; collecting color temperature data at a fixed frequency or by determining whether the device is moving, and comparing the color temperature data collected at the last moment; if the change value of the color temperature data is greater than the adjustment threshold, adjusting the color temperature of the screen. In order to avoid unnecessary power consumption caused by too frequent adjustment of the screen color temperature, the method of setting an adjustment threshold is used in this embodiment to control whether the screen needs to adjust the color temperature. The color temperature data can be re-acquired by fixing the frequency or determining whether the device is moving, and compared with the last collected data, to further determine whether the color temperature environment has changed, thereby avoiding frequent detection and adjustment of the color temperature and saving power of the terminal device.

[0067] Some methods or steps in the above embodiments correspond to some methods or steps in the embodiment of the aforementioned screen color temperature adjustment method 10. The specific functional effects have been described and will not be repeated here.
