Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The screen color temperature adjusting method and apparatus according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a method for adjusting a color temperature of a screen according to an embodiment of the present invention. As shown in fig. 1, the method includes:
The eye physiological signals include positions of pupils and eyeballs of the user, in some possible embodiments, the positions of the eyeballs of the user are detected according to the infrared sensor, and in other possible embodiments, the eye physiological signals of the user can be determined according to the eye image information of the user, which is acquired by the camera.
It should be understood that the eye physiological signal of the user may determine whether the viewpoint of the user is focused on the screen, and when the viewpoint of the user is focused on the screen, it is determined that the user is actually using the terminal device.
And 102, recording the duration of the viewpoint on the screen when the viewpoint is on the screen.
It is emphasized that, considering that in practical applications, the eyes of the user may briefly leave the screen, for example, the user may speak up and around teammates while playing the game using the terminal device, but such brief departure should not be regarded as the user stopping using the terminal device, and therefore, the duration of the recording viewpoint on the screen in the embodiment of the present invention includes a case where the time difference between the departure of the viewpoint of the user from the screen and the return to the screen is short, for example, when the viewpoint of the user from the first second to the third second is concentrated on the screen, but the viewpoint of the user leaves the screen at the fourth second, and the viewpoint of the user is concentrated on the screen again at the fifth second, the viewpoint of the user from the first second to the fifth second is regarded as continuously concentrated on the screen for five seconds.
And 103, judging whether the duration exceeds a preset threshold or not, and starting to calculate a real-time difference value between the duration and the preset threshold when the duration exceeds the preset threshold.
And 104, determining a real-time blue light filtering proportion corresponding to the real-time difference value according to the real-time difference value, and adjusting the current color temperature of the screen according to the real-time blue light filtering proportion, wherein the implementation difference value and the real-time blue light filtering proportion are in a direct proportion relation.
Specifically, the duration that the user viewpoint is concentrated on the screen is judged, and when the duration exceeds a preset threshold, it indicates that the current eyes of the user should start to enter a fatigue state, and the color temperature of the screen starts to be adjusted, so that the eye fatigue of the user is reduced. Of course, in order to provide better service using such personalized service between users, in which different users have differences in the duration of their point of view focused on the screen when they reach a fatigue state, in one embodiment of the present invention, the identity information of the user is obtained, which includes the occupation, age, and sex of the user, and the preset threshold is determined according to the identity information of the user, for example, when the user is a child, the preset threshold is relatively low, and when the user's occupation is a computer worker, the preset threshold is relatively low.
The method includes the steps of acquiring identity information of a user in different application scenes, as a possible implementation mode, pre-storing corresponding relations between the identity information of the user and fingerprint information, acquiring fingerprint information input by the user when the user uses a terminal device, for example, acquiring fingerprint information input by the user when the user unlocks, inquiring the pre-stored corresponding relations according to the fingerprint information input by the user, and acquiring corresponding identity information.
Further, when it is determined that the eyes of the user start to enter a fatigue state, the blue light filtering proportion is gradually reduced, so that the eye fatigue of the user is relieved, the adaptability of the eyes of the user is improved, and the comfort is improved.
In an embodiment of the present invention, a corresponding relationship between the real-time difference and the brightness reduction value of the blue pixel is pre-established, the corresponding relationship is queried according to the real-time difference, the brightness reduction value of the blue pixel corresponding to the real-time difference is obtained, and the brightness value of the blue pixel is reduced according to the brightness reduction value.
However, after a part of the blue light B is filtered, since the brightness of the screen is formed by the ratio of RGB, when the color temperature is adjusted, a part of the blue light is filtered, and the brightness is inevitably reduced due to B reduction.
Thus, in one embodiment of the present invention, as shown in fig. 2, after the step 104, the method further comprises:
Specifically, the current screen brightness may be obtained according to the brightness sensor, and the lowest value of the screen brightness matched with the current environment brightness is determined according to the environment brightness, that is, when the environment brightness is low, the set lowest value of the screen brightness is relatively high in order not to damage the eyes of the user, otherwise, when the environment brightness is high, the set lowest value of the screen brightness is relatively low in order not to damage the eyes of the user, and in the actual execution process, the environment brightness and the adapted lowest value of the screen brightness may be determined according to a large amount of experimental data, or may be manually set in advance by the user.
Specifically, the brightness of the screen after the brightness value of the blue pixel is reduced is detected, and when the brightness of the screen is less than or equal to the lowest brightness value of the screen, the brightness value of the blue pixel is stopped being reduced to ensure the service quality.
In another embodiment of the present invention, in order to compensate for the loss of screen brightness after blue light is filtered, the screen contrast after color temperature adjustment is determined, and the screen definition is improved by setting a relatively high contrast. Because different blue light filters the proportion and needs different contrast corresponding to different screen brightness in order to make the screen show clearly, consequently, set up the contrast database that contains screen colour temperature behind the blue light filters the proportion and screen contrast relation in advance, and then, obtain the screen colour temperature after the colour temperature regulation according to the blue light filters the proportion, inquire the contrast database that prestores, acquire the screen contrast that corresponds with screen colour temperature and carry out the regulation of screen contrast.
In another embodiment of the present invention, in order to compensate for the loss of screen brightness after blue light filtering, the pixel brightness of the red light and the green light after color temperature adjustment is determined, that is, a database containing a correspondence relationship between a screen color temperature after blue light filtering proportion and an increase in the brightness of the green light and the red light is preset, and then, the screen color temperature after color temperature adjustment is obtained according to the blue light filtering proportion, a pre-stored database is queried, green light and red light brightness increase values corresponding to the blue light filtering proportion are obtained, and the pixel brightness of the red light and the green light is adjusted according to the green light and red light brightness increase values.
Considering that in some application scenarios, when a user uses a terminal device, a screen position where a function provided by the terminal device is located is relatively fixed, for example, as shown in fig. 3, when the user uses a small screen of the terminal device to play a video, the user only uses a screen area corresponding to an interface where a player is located, so that, in order to save electric power, it is also possible to determine a screen area occupied when the current application program provides a function service, adjust a blue light filtering ratio in the screen area, and directly reduce screen brightness to the lowest for other screen areas.
In some application scenarios, a user does not need to execute the screen color temperature adjusting method according to the embodiment of the present invention due to reasons such as work requirements, for example, when the user uses an office application program for office work, in order to avoid that screen brightness is reduced due to blue light filtering to affect office efficiency of the user, a white list application may be preset, the screen color temperature adjusting method according to the embodiment of the present invention is used only when the current application does not belong to a white list application, and in some possible examples, an application program identifier currently running, such as an application program icon or the like, is obtained, and it is determined that the current application program does not belong to a preset white list identifier, and the screen color temperature adjusting method according to the embodiment of the present invention is used.
To sum up, the screen color temperature adjusting method of the embodiment of the present invention obtains an eye physiological signal of a user, determines whether a viewpoint of the user is on a screen according to the eye physiological signal, records a duration of the viewpoint on the screen when the viewpoint is on the screen, determines whether the duration exceeds a preset threshold, and starts to calculate a real-time difference between the duration and the preset threshold when the duration exceeds the preset threshold, and further determines a real-time blue light filtering ratio corresponding to the real-time difference according to the real-time difference, and adjusts a current color temperature of the screen according to the real-time blue light filtering ratio, wherein the implementation difference is in direct proportion to the real-time blue light filtering ratio. From this, when confirming user's eye fatigue, improve the blue light filtration ratio gradually for the accommodation process of this kind of colour temperature can be adapted to people's eye on the basis of protecting people's eye, has improved people's eye comfort level, and the practicality is higher.
