Embodiment
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the present invention.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that aspects more of the present invention are consistent.
Current most electronic equipment is all provided with range sensor and light intensity sensor.Range sensor can collect the distance value between the object in the screen front of electronic equipment and the screen of electronic equipment, is commonly used to the screen automatic distinguishing function after pressing close to face when realizing making a phone call.And light intensity sensor can collect the light intensity value in the screen front of electronic equipment, be commonly used to the function of the screen intensity realizing environmentally light intensity regulating screen self.The automatic switching method that the disclosure provides, can realize the auto sleep of Smartcover by distance value and light intensity value or automatically wake up.
Fig. 1 is the process flow diagram of a kind of automatic switching method according to an exemplary embodiment, and as shown in Figure 1, this automatic switching method is used for, in electronic equipment, comprising the following steps.
In step S101, the screen front obtaining electronic equipment is at not distance value in the same time and light intensity value;
In step s 102, whether the change of detecting distance value in time domain meets default distance change condition and whether the change of light intensity value in time domain meets default light intensity change condition;
In step s 103, if the change of distance value in time domain meets distance change condition and the change of light intensity value in time domain meets light intensity change condition, then control electronic equipment and carry out auto sleep or automatically wake up.
In sum, the automatic switching method that the present embodiment provides, by the screen front that obtains electronic equipment at not distance value in the same time and light intensity value; If detect that the change of distance value in time domain meets distance change condition and the change of light intensity value in time domain meets light intensity change condition, then control electronic equipment and carry out auto sleep or automatically wake up; Solve correlation technique must rely on the magnetometric sensor on electronic equipment problem when realizing the auto sleep of Smartcover or automatically waking up; Reach the electronic equipment not arranging magnetometric sensor also can realize the auto sleep of Smartcover or automatically wake up, only need this electronic equipment to be provided with common range sensor and the effect of light intensity sensor.
Fig. 2 A is the process flow diagram of another automatic switching method according to an exemplary embodiment, and as shown in Figure 2 A, this automatic switching method is used for, in electronic equipment, comprising the following steps.
In step s 201, the screen front obtaining electronic equipment is at not distance value in the same time and light intensity value;
Electronic equipment gathers screen front at not distance value in the same time every predetermined time interval by range sensor, such as, and 20 times per second.Electronic equipment also gathers screen front at not light intensity value in the same time every predetermined time interval by light intensity sensor.
Distance value is normally identical with the collection moment of light intensity value, and such as, distance value and light intensity value are from 0.00 second, collection per second 20 times; Also be likely that interval time lengths is identical, sampling instant is slightly different, and such as, distance value is from 0.00 second, collection per second 20 times, and light intensity value is start for 0.02 second, collection per second 20 times.As long as but the distance value collected in section at one time and light intensity value can characterize distance change during this period of time and light intensity changes.
In step S202, whether the change of detecting distance value in time domain meets distance change condition;
If the containment vessel on electronic equipment becomes closed condition from open mode, or becomes open mode from closed condition, the distance value of electronic equipment and light intensity value all can be caused to change.Electronic equipment detecting distance value can change whether meet distance change condition in time domain, and this distance change condition becomes closed condition for identification protecting shell from open mode, or becomes the event of open mode from closed condition.
Electronic equipment is current be in wake-up states time, whether the change of electronic equipment detecting distance value in time domain meets dormancy distance change condition, and dormancy distance change condition refers to that distance value becomes from the value being greater than predeterminable range threshold wake-up value the value being less than nearly zero threshold value of predeterminable range within scheduled duration.Such as, scheduled duration can be 1 second, and predeterminable range threshold wake-up value can be 10cm, and nearly zero threshold value of predeterminable range can be 0.3cm, if distance value became from the value being greater than 10cm the value being less than 0.3cm in 1 second, then think that the change of distance value in time domain meets dormancy distance change condition.
Electronic equipment is current be in dormant state time, whether the change of electronic equipment detecting distance value in time domain meets is waken distance change condition up, wakes distance change condition up and refers to that distance value becomes from the value being greater than predeterminable range threshold wake-up value the value being less than nearly zero threshold value of predeterminable range within scheduled duration.Such as, scheduled duration can be 1 second, and predeterminable range threshold wake-up value can be 10cm, and nearly zero threshold value of predeterminable range can be 0.3cm, if distance value became from the value being less than 0.3cm the value being greater than 10cm in 1 second, then think that the change of distance value in time domain meets and wake distance change condition up.
Above-mentioned testing process can be realized by the coprocessor (SensorHub) in electronic equipment, and coprocessor to be in the process of dormant state at electronic equipment also can the data of processes sensor.
For n the distance value collected in above-mentioned scheduled duration, at least to choose belong to two ends two distance values for above-mentioned detection, now accuracy is lower, but calculated amount is very little; If electronic equipment chooses whole n distance value for above-mentioned detection, then accuracy is higher, but calculated amount is very large.Depending on the difference of embodiment, k distance value between 2 and n can be chosen for above-mentioned detection.
In step S203, if the change of distance value in time domain meets distance change condition, then detect the change of light intensity value in time domain and whether meet light intensity change condition;
Because the testing result of distance value is always inaccurate, for this reason, electronic equipment also detects the Mandarin of light intensity value in time domain and whether meets light intensity change condition.This light intensity change condition becomes closed condition for identification protecting shell from open mode, or becomes the event of open mode from closed condition.
Electronic equipment is current be in wake-up states time, electronic equipment detects the change of light intensity value in time domain and whether meets dormancy light intensity change condition, and dormancy light intensity change condition refers to that light intensity value becomes from the value being greater than default light intensity threshold wake-up value the value being less than nearly zero threshold value of default light intensity within scheduled duration.
Electronic equipment is current be in dormant state time, whether the change of electronic equipment detection light intensity value in time domain meets is waken light intensity change condition up, wakes light intensity change condition up and refers to that light intensity value becomes from the value being greater than default light intensity threshold wake-up value the value being less than nearly zero threshold value of default light intensity within scheduled duration.
Above-mentioned testing process also can be realized by the coprocessor (SensorHub) in electronic equipment.Scheduled duration when detecting light intensity value is identical corresponding in other words with scheduled duration during detecting distance value.Such as, the distance value between A moment and B moment and light intensity value is belonged to.
For the N number of light intensity value collected in above-mentioned scheduled duration, at least to choose belong to two ends two light intensity values for above-mentioned detection, now accuracy is lower, but calculated amount is very little; If electronic equipment chooses whole N number of light intensity value for above-mentioned detection, then accuracy is higher, but calculated amount is very large.Depending on the difference of embodiment, K light intensity value between 2 and N can be chosen for above-mentioned detection.
In one example in which, suppose that scheduled duration is 1 second, predeterminable range threshold wake-up value can be 10cm, nearly zero threshold value of predeterminable range can be 0.3cm, presetting light intensity threshold wake-up value can be Xcd, presetting nearly zero threshold value of light intensity can be Ycd, then automatically wake up and illustrate as shown in Figure 2 B with the process of auto sleep.
In step S204, if the change of distance value in time domain meets distance change condition and the change of light intensity value in time domain meets light intensity change condition, then control electronic equipment and carry out auto sleep or automatically wake up.
If the change of distance value in time domain meets dormancy distance change condition and the change of light intensity value in time domain meets dormancy light intensity change condition, then control electronic equipment and carry out auto sleep.
If the change of distance value in time domain meets and wake distance change condition up and the change of light intensity value in time domain meets and wake light intensity change condition up, then control electronic equipment and carry out auto sleep.
In sum, the automatic switching method that the present embodiment provides, by the screen front that obtains electronic equipment at not distance value in the same time and light intensity value; If detect that the change of distance value in time domain meets distance change condition and the change of light intensity value in time domain meets light intensity change condition, then control electronic equipment and carry out auto sleep or automatically wake up; Solve correlation technique must rely on the magnetometric sensor on electronic equipment problem when realizing the auto sleep of Smartcover or automatically waking up; Reach the electronic equipment not arranging magnetometric sensor also can realize the auto sleep of Smartcover or automatically wake up, only need this electronic equipment to be provided with common range sensor and the effect of light intensity sensor.
Need supplementary notes a bit, relative to distance value, light intensity value is more easily subject to the interference of environmental factor and human factor.Only measure from the threshold angle of light intensity threshold wake-up value and nearly zero threshold value of light intensity, be very easy to erroneous judgement.For this reason, can be corrected by light sensation Pattern (figure) and realize " detecting the change of light intensity value in time domain whether meet dormancy light intensity change condition or wake light intensity change condition up " step, comprise following sub-step:
1, pre-recorded SMART SKIN is become the first light intensity curve in closed condition process from open mode in the screen front of electronic equipment; Dormancy light intensity curve is generated according to the first light intensity curve; And/or; Pre-recorded SMART SKIN is become the second light intensity curve in open mode process from closed condition in the screen front of electronic equipment; Generate according to the second light intensity curve and wake light intensity curve up.
This sub-step is equivalent to a training process.Electronic equipment can point out user that SMART SKIN is become closed condition from open mode, or becomes open mode from closed condition, and electronic equipment record light intensity curve is in the process to generate dormancy light intensity curve or to wake light intensity curve up.This process can be carried out repeatedly, adds up and obtains comparatively rational dormancy light intensity curve or wake light intensity curve up.Electronic equipment is preserved this dormancy light intensity curve or is waken light intensity curve up.
2, when detecting, electronic equipment is by change and the pre-recorded dormancy light intensity curve of light intensity value in time domain or wake light intensity curve up and carry out similarity matching;
Current be in wake-up states time, the change of light intensity value in time domain and pre-recorded dormancy light intensity curve are carried out similarity matching by electronic equipment.
Current be in dormant state time, the change of light intensity value in time domain and the pre-recorded light intensity curve that wakes up are carried out similarity matching by electronic equipment.
If 3 similarities simulated with dormancy light intensity curve higher than first threshold, then determine whether the change of light intensity value in time domain meets dormancy light intensity change condition;
If 4 with wake similarity that light intensity curve simulates up higher than Second Threshold, then determine whether the change of light intensity value in time domain meets and wake light intensity change condition up.
In another example, suppose that scheduled duration is 1 second, predeterminable range threshold wake-up value can be 10cm, nearly zero threshold value of predeterminable range can be 0.3cm, presetting light intensity threshold wake-up value can be Xcd, and presetting nearly zero threshold value of light intensity can be Ycd, and dormancy light intensity curve is a, waking change curve up is b, then automatically wake up and illustrate as shown in Figure 2 C with the process of auto sleep.
Obviously, detect the change of light intensity value in time domain by matching light intensity curve whether meet dormancy light intensity change condition or wake light intensity change condition up.Not only consider the degree of conformity of light intensity change in threshold angle, also contemplate the degree of conformity in change procedure angle, so the degree of accuracy of testing result is higher.
Also need to illustrate in addition a bit, the change that above-described embodiment detects light intensity value again with the change of first detecting distance value illustrates.But the change of the change in other embodiments, first detecting light intensity value detecting distance value again.Also namely, above-mentioned steps S201 and S202 can adopt following two steps to realize:
1, detect the change of light intensity value in time domain and whether meet light intensity change condition;
If the change of 2 light intensity values in time domain meets light intensity change condition, then whether the change of detecting distance value in time domain meets distance change condition;
In other embodiment, distance value and light intensity value also can detect simultaneously.Also namely, whether the change of electronic equipment detecting distance value in time domain meets distance change condition the and whether change of parallel detection light intensity value in time domain meets light intensity change condition.
