Fig. 2 is the structural representation of portable terminal of the present invention.
Embodiment
For making the object of the invention, technical scheme and advantage clearer, below in conjunction with embodiment and accompanying drawing, to further explain of the present invention.
For built-in gyroscope, and camera has the portable terminal of anti-trembling function, can adopt method flow shown in Figure 1, opens the camera anti-trembling function automatically according to the change in displacement value that gyroscope provides.The flow process of Fig. 1 may further comprise the steps:
Step 101 receives the enabled instruction of opening camera.
The user opens the camera function of portable terminal, gets into exposal model; Correspondingly, portable terminal receives the enabled instruction of the unlatching camera of user's input, and then, execution in step 102 and 103 is carried out the judgement whether camera need prevent trembling operation.
Step 102 is obtained the change in displacement value from gyroscope.
Step 103 judges that the change in displacement value is whether in the pre-set threshold scope, if then send the anti-open command of trembling to camera.
If judge the change in displacement value not in the pre-set threshold scope, then do not process.
If judge the change in displacement value in the pre-set threshold scope, then send the anti-open command of trembling, after camera is received and prevented trembling open command, just can prevent trembling processing to camera.
In the present embodiment, gyroscope can adopt three-axis gyroscope, and to carry out the test of change in displacement value, three comprise X axle, Y axle and Z axle.Carry out the change in displacement value that threshold range is judged from gyroscope being used to of obtaining; Be at least one group; Every group of change in displacement value comprises the change in displacement value on X axle, Y axle and three directions of Z axle; Set corresponding threshold value separately on X axle, Y axle and three directions of Z axle respectively, three directions corresponding threshold respectively can have nothing in common with each other.
If in the step 102 of Fig. 1 flow process, the change in displacement value of obtaining from gyroscope is one group of change in displacement value; Then step 103 is said judges whether the change in displacement value comprises in the pre-set threshold scope: judge that change in displacement value on X axle, Y axle and three directions of Z axle is whether all less than corresponding threshold separately; If then determine the change in displacement value in the pre-set threshold scope.
If in the step 102 of Fig. 1 flow process, the change in displacement value of obtaining from gyroscope is at least two group change in displacement values; Then step 103 is said judges whether the change in displacement value comprises in the pre-set threshold scope:
Every group of change in displacement value judged, judged that change in displacement value on X axle, Y axle and three directions of Z axle is whether all less than corresponding threshold separately, if then determine this group change in displacement value less than threshold value;
Judge and whether respectively organize the change in displacement value, if then determine the change in displacement value in the pre-set threshold scope all less than threshold value.
The method of gyroscope testing mobile terminal change in displacement value is a prior art, carries out brief description here.As the three dimensions central point, in the T, the coordinate information that obtains perception that does not stop calculates the changes in coordinates value in all angles to gyroscope, obtains the change in displacement value on X axle, Y axle and three directions of Z axle at the appointed time with the portable terminal center.Need to prove that the change in displacement value of three directions that gyroscope calculates is a vector value, in an application of the invention, be used to judge when whether portable terminal is in dither state, get the absolute value of each displacement changing value.If Fig. 1 process step 102 said change in displacement values of obtaining from gyroscope are N group change in displacement value, then gyroscope in the T, obtains N group coordinate sample information at the appointed time; According to every group of sampled data, calculate the change in displacement value on X axle, Y axle and three directions of Z axle respectively again.
