Embodiment one

FIG. 1 shows the first implementation process of the method for adjusting screen brightness provided by Embodiment 1 of the present invention. For ease of description, only parts related to the present invention are shown.

In the embodiment of the present invention, the method is applied to a smart terminal, and the smart terminal includes a touch screen or screen. The intelligent terminal includes, but is not limited to, a mobile phone, a pocket computer (Pocketpersonal Computer, PPC), a palmtop computer, a personal digital assistant (Personal Digital Assistant, PDA), etc., preferably a smart phone, a tablet computer, etc. An eye tracking system is also installed on the smart terminal.

As shown in Figure 1, the method includes:

In step S101, the user's eyeball activity information is acquired.

In the embodiment of the present invention, the user's eye activity information is preferably acquired through eye tracking technology, so as to determine the target the eye is looking at. The eye tracking system uses low-power infrared light to irradiate the user's eyeball at a high speed, and then the sensor captures the light reflected from different parts such as the pupil, iris, and cornea, and then analyzes it with a preset algorithm to determine the target of the eyeball.

In step S102, the focus area of the user's eyeballs on the screen of the smart terminal is acquired according to the eyeball activity information.

Preferably, in the embodiment of the present invention, the focus point of the user's eye on the screen of the smart terminal is obtained first through eye tracking technology; then, according to the focus point, a preset range centered on the focus point on the screen is determined, and the The preset range acts as the focus area. Wherein, the focus area is preferably a circular area, a square area or a rectangular area centered on the focus point.

In step S103, adjust the brightness of the focused area on the screen to the first display brightness, and adjust the brightness of the remaining areas on the screen to the second display brightness.

Wherein, the rest area is an area on the screen except the focus area.

In the embodiment of the present invention, after the focus area of the user's eyeball activity is obtained, and thus the area that the user is currently focusing on on the screen is obtained, the brightness of the focus area is adjusted to the first display brightness, and the screen is divided by the The brightness of other areas outside the focused area is adjusted to be the second display brightness. Preferably, the first display brightness is higher than the second display brightness, so that the focus area where the user's eyes are located is brighter than the non-focus area, which helps the user to concentrate on the screen area they are looking at; and The brightness of other areas on the screen except the focus area is reduced, which can reduce the power consumption of the smart terminal and prolong the standby time of the smart terminal.

The embodiment of the present invention adjusts the brightness of different areas on the screen of the smart terminal based on the focus information of the user's eyeballs; by acquiring the user's eyeball activity information; according to the eyeball activity information, the focus area of the user's eyeballs on the smart terminal screen is obtained; The brightness of the focus area is the first display brightness, and the brightness of the remaining areas on the adjustment screen is the second display brightness; wherein, the remaining areas are areas on the screen except the focus area; thereby realizing different display on the screen The brightness adjustment of the area greatly reduces the power consumption of the display or touch screen, and helps the user to concentrate on the area of the screen that he is looking at.

Embodiment two

FIG. 2 shows a second implementation flow of the method for adjusting screen brightness provided by Embodiment 2 of the present invention. For ease of description, only parts related to the present invention are shown.

In order to improve the accuracy of determining the focus area of the user's eyeballs, the embodiment of the present invention determines whether the user is looking at the area on the screen of the smart terminal by detecting the focus time of the user's eyeballs. For details, refer to the description of the embodiment in FIG. 2 .

As shown in Figure 2, the method includes:

In step S201, the user's eye movement information is acquired through eye tracking technology.

In step S202, the focus point of the user's eyeballs on the screen of the smart terminal is acquired according to the eyeball activity information.

In step S203, a preset range centered on the focus point on the screen is determined according to the focus point, and the preset range is used as a focus area.

In step S204, the dwell time of the user's eyeballs on the focus area is calculated.

In step S205, it is judged whether the residence time is greater than a preset threshold.

Wherein, the preset threshold is obtained according to actual test experiments, and is preferably 0.5 seconds. In this embodiment of the present invention, timing starts from the focus point of the user's eye on the screen of the smart terminal obtained through eye tracking technology. If you are looking at the focus area of the screen, execute step S206; otherwise, the time interval between the acquisition of the focus point and the first subsequent focus point that is not within the focus area is less than the preset When the threshold is exceeded, it is determined that the user is not looking at the screen. At this time, return to step S201 to reacquire the focus area of the user's eyeball.

In step S206, when the dwell time is greater than a preset threshold, the brightness of the focused area on the screen is adjusted to a first display brightness, and the brightness of other areas on the screen is adjusted to a second display brightness.

Preferably, since the focus point is obtained, if the user's focus point remains within the range of the focus area within the time period corresponding to the preset threshold (such as 0.5 seconds), then the time corresponding to the preset threshold has passed After a period of time (eg: 0.5 second after the focus point is acquired), adjust the brightness of the focused area on the screen to the first display brightness, and adjust the brightness of the remaining areas on the screen to the second display brightness. Wherein, the first display brightness is higher than the second display brightness, so that the brightness of the focused area of the screen is set higher than that of the non-focused area according to the focus of the user's eyeballs, so that the user can concentrate on the screen area that the user is looking at and effectively reduce the power consumption of the smart terminal, which is beneficial to prolong the standby time of the smart terminal.
