Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

Fig. 3 is a flowchart illustrating a screen control method according to an embodiment of the present invention, which is applied to a terminal to control a screen of the terminal, so as to improve user experience. As shown in fig. 3, the method comprises the steps of:

in step S300, a plurality of frames of consecutive pictures within a preset time period are acquired.

In this embodiment, the acquisition of the multi-frame picture may be performed by presetting a time period for extraction, that is, when the time reaches a certain time, the multi-frame continuous picture in the current time period may be extracted.

In step S302, a high-frequency dynamic region and a low-frequency dynamic region in the screen are determined according to the multi-frame continuous pictures.

In this embodiment, the screen is composed of a plurality of pixel points, and the position of each pixel point constitutes the range coordinate of the whole screen, that is, the distance between each pixel point is the minimum distance unit of the screen. Once the coordinates of the screen pixel points are obtained, the range and the size of any area of the screen can be obtained.

Specifically, the step of determining a high-frequency dynamic region and a low-frequency dynamic region in the screen according to the multi-frame continuous pictures specifically includes: analyzing the pixel change in the current screen through the multi-frame continuous pictures; if the pixel change in the current screen is larger than a preset value, determining the range of the pixel change larger than the preset value as a high-frequency dynamic area; and if the pixel change in the current screen is smaller than the preset value, determining the range of the pixel change smaller than the preset value as a low-frequency dynamic area. For the screen, the change of the pixel value of each pixel finally shows the change of the graph, and whether the current graph display is changed or not can be judged by detecting the change of the pixel value (namely, the RGB value). If the pixel value change of a certain area exceeds a certain preset value, the area is a frequently-changed area, namely the high-frequency dynamic area, otherwise, other areas of the screen are low-frequency dynamic areas.

In step S304, the on-screen coordinate ranges of the high-frequency dynamic region and the low-frequency dynamic region are calculated.

Specifically, firstly, the coordinates of the pixel points in the current screen, where the pixel change is greater than a preset value, are determined. Secondly, determining the coordinate range of the high-frequency dynamic region according to the pixel point coordinates of which the pixel change is larger than a preset value. And thirdly, determining the coordinate range of the low-frequency dynamic region according to the pixel point coordinate distribution of the current screen and the pixel point coordinates with the pixel change larger than the preset value, namely subtracting the pixel coordinates with the pixel change larger than the preset value in the screen from the size of the screen to form the coordinate range of the low-frequency dynamic region.

In step S306, the refresh frequency in the coordinate range of the high-frequency dynamic region and the refresh frequency in the coordinate range of the low-frequency dynamic region are adjusted according to a preset rule.

Specifically, the step of giving the region range of the visual central region and the refresh frequency different from each other to the region range of the edge region according to the preset rule specifically includes: calculating an area ratio of a region extent of the visual central region to the edge region extent; giving different refresh frequencies to the region range of the visual center region and the edge region range according to the area ratio. The step of giving the visual central area a different refresh frequency to the area extent of the visual central area and the edge area extent according to the area ratio may further include two embodiments as follows:

in the first embodiment, first, an optimal refresh frequency of a screen of the mobile terminal is obtained, where the optimal refresh frequency may be a highest frequency that can be supported by the screen; secondly, endowing the optimal refreshing frequency to the coordinate range of the high-frequency dynamic region; then, multiplying the highest refreshing frequency by the area ratio to obtain a first adjusting refreshing frequency; and finally, endowing the first adjusting and refreshing frequency to the coordinate range of the low-frequency dynamic region. In the present embodiment, in general, the area ratio is smaller than 1 when the coordinate range of the high-frequency dynamic range is smaller than the coordinate range of the low-frequency dynamic range. And if the coordinate range of the high-frequency dynamic region is larger than that of the low-frequency dynamic region, the area ratio is the area ratio of the coordinate range of the low-frequency dynamic region to that of the high-frequency dynamic region. Namely, the final effect is to ensure that the screen refresh frequency in the coordinate range of the high-frequency dynamic region is greater than the screen refresh frequency in the coordinate range of the low-frequency dynamic region.

In a second embodiment, the step of adjusting the refresh frequency in the coordinate range of the high-frequency dynamic region and the coordinate range of the low-frequency dynamic region according to the area ratio further includes: firstly, acquiring the current refreshing frequency of a screen of the mobile terminal; secondly, multiplying the current refreshing frequency by the area ratio to obtain a second adjusting refreshing frequency; then, multiplying the current refreshing frequency by the inverse proportion of the area ratio to obtain a third adjusting refreshing frequency; then, endowing the second adjustment refreshing frequency to the coordinate range of the low-frequency dynamic region; and finally, giving the third adjusting and refreshing frequency to the coordinate range of the high-frequency dynamic region. In this embodiment, the area ratio is less than 1. Namely, the technical effect of the final realization is that the screen refresh frequency in the coordinate range of the high-frequency dynamic region is higher than the refresh frequency in the coordinate range of the low-frequency dynamic region.

In step S308, content display is performed based on the adjusted refresh frequency.

In the present embodiment, the boundary region between the high-frequency dynamic region and the low-frequency dynamic region is determined according to the coordinate ranges of the high-frequency dynamic region and the low-frequency dynamic region; and performing mode feathering treatment on the boundary area. Because the difference of the refresh rate of the junction of the high-frequency refreshing area and the low-frequency refreshing area is large, the edge can flash, and the high-frequency and low-frequency boundary edge can be fuzzified in the screen, so that the feathering treatment is carried out on the boundary area of the high-frequency dynamic area and the low-frequency dynamic area, and the visual experience of the screen is better.

In addition, the screen control method further includes: and when the screen receives a screen-off instruction, restoring all ranges of the screen to the initial refreshing frequency. Specifically, when the user turns off the screen, an exit condition is given to the current screen control mechanism, that is, the refresh frequency setting on the screen is restored to the initial state.

Through implementing the above mode, can guarantee the best experience of user's vision, also reduced the consumption of whole screen simultaneously, and then promoted the holistic continuation of the journey power in terminal, promoted user experience.
