The information of each pixel gone out onto display, and physics video memory is the important component of video card, and display chip has been handled
Pixel data can be saved in after pixel data in physics video memory, then read out pixel from physics video memory by digital analog converter
Data simultaneously convert digital signals into analog signal, are finally come out by the screen display of mobile device.In the embodiment of the present invention, when
Pixel data can be saved in physics video memory by display chip after having handled pixel data, therefore can pass through the physics of mobile device
It is buffered in the pixel value for getting pixel in physics video memory in preset sampling time section according to preset sampling time interval.
In some embodiments of the invention, the clocking method of sampling time section and every sampling time interval timing touch
The mode that hair step 101 starts to perform can specifically be realized by timer come clocked flip, for example, sampling time section is 1s,
Sampling time interval is 20ms, then when the timer time of sampling time section starts, timer just triggers step 101 every 20ms
Perform once.
102nd, according in the judgement of the pixel value of the pixel value of the pixel of above-mentioned first frame and the pixel of above-mentioned second frame
State whether physics video memory changes.
Wherein, step 103 is performed when above-mentioned physics video memory changes.
In embodiments of the present invention, the sampling time before a sampling time interval is obtained by step 101 statistics
Collect data content in the physics video memory of mobile device for the pixel of the first frame pixel value, the sampling time interval it
It is the pixel value of the pixel of the second frame, Ran Hougen that sampling time afterwards, which collects data content in the physics video memory of mobile device,
Judge whether physics video memory changes according to the pixel value of the pixel of the first frame and the pixel value of pixel of the second frame.Its
In, in the embodiment of the present invention when physics video memory changes, digital analog converter reads out pixel data simultaneously from physics video memory
Analog signal is converted digital signals into, screen-picture will produce change when finally being come out by the screen display of mobile device,
Therefore whether the embodiment of the present invention is changed by physics video memory and gets the screen-picture of mobile device and display whether to become
Change, so as to be changed the statistics of number to the frame per second of mobile device, and according to sampling time section so as to calculating mobile device
Real time frame rate, refer to the description of subsequent embodiment.It should be noted that in embodiments of the present invention according to above-mentioned first frame
The pixel value of the pixel of the pixel value of pixel and above-mentioned second frame judge above-mentioned physics video memory whether change have it is a variety of
Implementation, for example, can be collected respectively for two sampling times before and after a sampling time interval
The pixel value of pixel is compared frame by frame, can also be for being adopted at one so as to get whether physics video memory changes
The pixel value for the pixel that two sampling times before and after sample time interval collect respectively carries out summation inspection code
Compare, so as to get whether physics video memory changes, specifically can flexibly be set with application scenarios in actual applications, this
Place for illustrative purposes only, does not limit.
It should be noted that in some embodiments of the invention, in step 102 when above-mentioned physics video memory becomes
Step 103 is performed during change, refers to the description of subsequent step.In addition, when above-mentioned physics video memory does not change, it is necessary to again
Triggering step 101 performs again, and what is simply got with the increase of the timer time of timer is between the latter sampling time
The pixel value of the pixel for the frame that sampling time before and after collects.
103rd, when above-mentioned physics video memory changes, the frame per second statistical value of above-mentioned mobile device is increased into a statistics step
It is long.
Wherein, by the judgement whether to be changed to physics video memory, show so as to get the screen-picture of mobile device
Show whether changed, for example, the screen-picture of mobile device, which is shown, when physics video memory changes is become
