S101: performing statistics on the number of pixel points in the display data based on grayscale.
Herein, the grayscale refers to a level of shades that surface feature electromagnetic wave radiation intensity is represented on a black-white image, and it is a scale for dividing surface feature spectrum character.
The display data can be particularly data of a current frame of picture to be displayed in a mobile device.
It can be understood that the data of the current frame of picture to be displayed can be transmitted before being displayed. For example, the data is transmitted from a server terminal to a mobile device terminal, and is transmitted to a display screen via an interface of the mobile device used for receiving data.
In related art, the display data is generally transmitted by using a same resolution. However, the screen of the mobile device does not need to be always maintained at a high resolution in certain scenarios.
Therefore, there is proposed in the embodiment of the present disclosure to perform variable resolution transmission on the data displayed on the mobile device.
Generally, in a display picture corresponding to display data, grayscale for different pixel points are different. Therefore, for different display data, distribution of grayscale of all the pixel points in respective display data is also different. Therefore, statistics can be performed on the number of the pixel points in the display data based on the grayscale.
S102: adjusting an initial output resolution according to a result obtained from the statistics.
The initial output resolution may be a default resolution of the mobile device, or may be a resolution designated by a user for the mobile device, to which no limitation is made.
In the embodiment of the present disclosure, a grayscale threshold value can be set. Further, statistics are performed on the number of the pixel points in the display data whose grayscale value is greater than the grayscale threshold value, and statistics are performed on the number of the pixel points in the display data whose grayscale value is smaller than or equal to the grayscale threshold value, to obtain a statistical result.
Optionally, performing statistics on the number of the pixel points in the display data based on grayscale comprises: counting the number of pixels in the display data whose grayscale is smaller than or equal to the first grayscale threshold value, to obtain a first count; counting the number of pixels in the display data whose grayscale is greater than the first grayscale threshold value and smaller than or equal to a second grayscale threshold value, to obtain a second count, wherein the first grayscale threshold value is smaller than the second grayscale threshold value; counting the number of pixels in the display data whose grayscale is greater than the second grayscale threshold, to obtain a third count.
Herein, the first grayscale threshold value/the second grayscale threshold value can be predetermined.
The first scale gray threshold value/second grayscale threshold value can be set by factory programs of the mobile device in advance, or can be set by the user according to his/her own requirements, to which no limitation is made.
In the embodiment of the present disclosure, when statistical results belong to different statistical cases, different adjustments can be made to the initial output resolution.
S103: transmitting the display data according to an adjusted output resolution.
In the embodiment of the present disclosure, since statistics are performed on the number of the pixel points in the display data based on the grayscale, human eyes' physiological characteristics of being sensitive to the brightness can be utilized, in particular, a pixel grayscale statistical unit can be pre-configured in the mobile device to perform statistics on the number of the pixel points in the display data and distinguish the cases that do not need to display with a high resolution according to the statistical result, so as to change the resolution dynamically, change the amount of data transmitted from AP system in the mobile device to a TFT-LCD, thereby reducing the power consumption of the mobile device terminal system.
In the embodiment, by performing statistics on the number of the pixel points in the display data based on the grayscale, adjusting the initial output resolution according to the result obtained from the statistics, and transmitting the display data according to the adjusted output resolution, it is capable of reducing the system power consumption of the mobile device effectively.
By referring to
S201: counting the number of pixels in the display data whose grayscale is smaller than or equal to the first grayscale threshold value, to obtain a first count.
S202: counting the number of pixels in the display data whose grayscale is greater than the first grayscale threshold value and smaller than or equal to the second pixel gray threshold value, to obtain a second count, wherein the first grayscale threshold value is smaller than the second grayscale threshold value.
S203: counting the number of pixels in the display data whose grayscale is greater than the second grayscale threshold value, to obtain a third count.
Herein, a pixel grayscale statistical unit can be pre-configured in the mobile device, three counters are configured in the pixel grayscale statistical unit, and the three counters perform statistics on the number of the pixel points in the display data that have different grayscale values respectively.
For example, it can be assumed that the first grayscale threshold value is b, and the second grayscale value is a, wherein a is greater than b. Grayscale of all the pixel points in the data to be displayed currently can be traversed, and when grayscale of a pixel point is greater than a, a count value of a counter Counter_A is incremented by 1; when the grayscale is smaller than or equal to b, a count value of a counter Counter_C is incremented by 1; when the grayscale is between a and b, a count value of a counter Counter_B is incremented by 1. After the traversal ends up, the count value in the Counter_A is the number of the pixel points in the display data whose grayscale is greater than a, the count value in the Counter_B is the number of the pixel points in the image whose grayscale is greater than b and smaller than or equal to a, and the count value in the Counter_C is the number of the pixel points in the image whose grayscale is smaller than or equal to b.
Correspondingly, the count value in the Counter_C is a first count, the count value in the Counter_B is a second count, and the count value in the Counter_A is a third count.
S204: determining one statistical case, to which the result belongs, among a plurality of statistical cases, wherein the plurality of statistical cases include: a first statistical case, a second statistical case, a third statistical case, and a fourth statistical case. The first statistical case is that the first count is the maximum value of the three counts; the second statistical case is that the second count is the maximum value of the three counts and the second count is greater than or equal to a predetermined threshold value; the third statistical case is that the third count is the maximum value of the three counts; and the fourth statistical case is that the second count is the maximum value of the three counts and the second count is smaller than the predetermined threshold value.
Optionally, the predetermined threshold value is a product of a predetermined percentage value and the number of total pixels of the display data.
Optionally, the predetermined percentage value is ⅔.
S205: adjusting the initial output resolution according to the determined statistical case.
Optionally, the step of adjusting the initial output resolution according to the determined statistical case comprises: if the result is the first statistical case, the initial output resolution is adjusted into a first predetermined output resolution, and takes the first predetermined output resolution as an adjusted output resolution; if the result is the second statistical case, then the initial output resolution is not adjusted; if the result is the third statistical case, the initial output resolution is not adjusted; if the result is the fourth statistical case, the initial output resolution is adjusted into a second predetermined output resolution, and the second predetermined output resolution is taken as an adjusted output resolution.
Optionally, the initial output resolution is greater than the first predetermined output resolution or the second predetermined output resolution.
The first predetermined output resolution and the second predetermined output solution may be same or may be different.
For example, the AP system in the mobile device can compare and judge the size of the count values in the Counter_A, Counter_B, and Counter_C. When the count value of the Counter_A is the maximum value, that is, in all the pixel points of the display data corresponding to one image, the amount of the pixel points with grayscale greater than a is relatively lager, the AP system of the mobile device is set to output the display data with the initial output resolution, and usually this initial output resolution is a relatively high resolution. When the count value in the Counter_C is the maximum value, that is, in all the pixel points of the display data corresponding to one image, the amount of the pixel points with grayscale smaller than or equal to b is relatively lager, the AP system of the mobile device is set to transmit the display data by reducing the resolution, for example, adjusting the initial output resolution to the first predetermined output resolution which is pre-determined and smaller than the initial output resolution. When the count value in the Counter_B is the maximum value, and the count value in the Counter_B is greater than or equal to ⅔ of the number of total pixels of the display data, that is, in all the pixel points of the display data corresponding to one image, the amount of the pixel points with grayscale falling between the grayscale a and the grayscale b is relatively large, the initial output resolution is not adjusted. When the count value in the Counter_B is the maximum value, and the count value in the Counter_B is smaller than ⅔ of the number of total pixels of the display data, the initial output resolution can be adjusted to the second predetermined output resolution which is pre-determined and smaller than the initial output resolution.
Further, when the counter value in the Counter_B is the maximum value, and the counter value in the Counter_B is greater than or equal to ⅔ of the number of total pixels of the display data, that is, in all the pixel points of the display data corresponding to one image, the amount of the pixel points with grayscale falling between the grayscale a and the grayscale b is relatively large, a judgement may be made by detail information on the image. If there is little detail information on the image, the AP system of the mobile device is set to transmit the display data by reducing the resolution; otherwise, transmission of the display data is performed with the initial output resolution.
In the embodiment, by performing statistics on the number of pixel points in the display data based on the grayscale, adjusting the initial output resolution according to the result obtained from the statistics, and transmitting the display data according to the adjusted output resolution, it is capable of reducing the system power consumption for the mobile device effectively. By determining the statistical case to which the result belongs and adjusting the initial output resolution according to the determined statistical case, it is capable of adjusting the output resolution according to the actual situations, so that the display effect of the display data is guaranteed effectively while the adjustment flexibility is improved.
