Embodiment
Below in conjunction with accompanying drawing more detailed description is carried out in preferred embodiment of the present invention.
Mobile phone photograph method for previewing of the present invention is applied to comprise the smart mobile phone of processor.This smart mobile phone is entering under the exposal model, and the size of the preview frame of taking pictures rate score can affect the battery of mobile phone power consumption.
As shown in Figure 1, use the mobile phone of the inventive method to include voltage detection module 12, processor resource control module 11 and preview resource control module 13.On this basis, 3 steps of realization the inventive method are as follows:
A, battery voltage detection module 12 detect battery of mobile phone voltage after receiving the mobile phone photograph instruction, and battery of mobile phone voltage testing result is sent to processor resource control module 11;
The cell voltage result that B, 11 pairs of processor resource control modules detect carries out analytic operation, and produces corresponding preview resource control signal, and signal is sent to preview resource control module 13;
C, preview resource control module 13 are carried out corresponding mobile phone photograph instruction for previewing according to preview resource control signal.
In conjunction with Fig. 2, the flow chart of an embodiment of mobile phone photograph method for previewing of the present invention is described, herein, smart mobile phone is for only comprising the single mode pattern of automatic mode.In other words, smart mobile phone only has automatic mode, and so-called automatic mode is to allow the frame per second setting meet the desired numerical value of curve shown in Figure 5.Such as Fig. 5, when cell voltage was in 3-3.4V, selecting frame per second was 12, and when cell voltage was in 3.4-3.5V, optimal frame rate was 13 ... when cell voltage was in 4.1-4.2V, optimal frame rate was 20.For realizing that the frame per second under the single automatic mode automatically arranges according to supply voltage, to in memory cell, preserve in advance a table of a frame per second-cell voltage relation, utilize this table, can be according to cell voltage, find corresponding frame per second what are, had such table can be more reasonable than the adjustment of direct basis cell voltage.And the relation of the voltage in this table and frame per second also can change according to the difference of voltage-electric weight relation (similar represent such as Fig. 4).
Fig. 2 implements in the flow chart of the inventive method, and the detection of cell voltage is had 9 grades, and every grade has a voltage range, and to the numerical value of a frame per second should be arranged, the numerical value among Fig. 2 embodiment represents it is corresponding with the curve of Fig. 5.The specific implementation process is as follows:
At frame S
0In, the residing scope of detection of handset cell voltage namely detects cell voltage, judges its residing scope, afterwards, and according to frame S
1The frame per second that middle memory cell prestores-cell voltage table is searched and obtained the preview frame per second, and is last, carries out this frame per second, thereby realizes frame per second and the cell voltage auto-associating of mobile phone photograph preview, reaches energy-saving effect.
In conjunction with Fig. 3, another embodiment of the present invention is described, in this embodiment, smart mobile phone can be provided with energy-conservation and automatic two kinds of patterns.The frame per second of automatic mode is to arrange according to voltage such as the first embodiment, and is energy-conservation especially such as needs, can be under energy saver mode, not tube voltage what frame per second is controlled at a predetermined numerical value.
With reference to figure 3, in frame S1, judge whether mobile phone is in energy saver mode, if the current energy saver mode that is in of mobile phone arranges frame per second and be preset value (for example 14); If the current automatic mode that is in of mobile phone afterwards, on frame S2, detects the residing scope of cell voltage, afterwards, according to frame S
3The frame per second of middle memory cell-cell voltage table is searched and is obtained the preview frame per second and implement this frame per second.This double mode frame per second design, the flexibility that has improved the energy-conservation aspect of mobile phone.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
