For example, when object is between light source and photosensitive sub-pixel, then photosensitive sub-pixel can obtain weaker optical signal or
The intensity of person's light radiation；When object edge removes the position between light source and photosensitive sub-pixel, then detection object edge
Photosensitive sub-pixel can obtain relatively strong (relative to object between light source and photosensitive sub-pixel) because of the not blocking of object
Optical signal or the intensity of light radiation, so that the parameter value of the photosensitive sub-pixel of corresponding position pixel intensity signal obtained produces

This to be detected the position mark for the photosensitive sub-pixel that ambient brightness changes as object pixel coordinate.
Wherein, in the T1 period, if the object of A1 is changed to the second state, the edge placement of the object from first state
Because of brightness change, in the photosensitive sub-pixel of light sensor corresponding position, the picture at two moment which obtains
Plain luminance signal also can be different.The photosensitive sub-pixel that pixel intensity signal has variation can be marked at this time, thus shape
At the array of figure as shown in B1.
Likewise, in the T2 period, it, at this time can be bright by pixel if the object of A2 is changed to the second state from first state
The photosensitive sub-pixel that degree signal has variation is marked, so as to form the array of figure as shown in B2.
The variation characteristic of the object pixel coordinate in array of figure by comparing above-mentioned B1 and B2, can be by algorithm only
The variation characteristic for calculating the object pixel coordinate determines motion track of the object in the T1 period into the T2 period, namely past Fig. 2

Wherein, operation response can be artificially defined preset operation response.
In some embodiments, operation response may include the bright screen of electronic equipment, unlocker device, put out screen, starting in advance
If application program, screenshotss or the one or more operations response for executing system function.
For example, it is assumed that object be human body hand, if by the hand of human body to relative to electronic equipment left stroke with
It opens to establish between the screen of electronic equipment and has mapping relations.At this time if electronic equipment detects that the motion track of object is phase
Left stroke for electronic equipment, then open the screen of electronic equipment.
Correspondingly, the different operation response for the different motion tracks and electronic equipment that can be will test is associated,
A variety of different operations are carried out to electronic equipment so that only can be realized by gesture, improve operating efficiency.
From the foregoing, it will be observed that according to instruction, there are the motion tracks that the pixel intensity signal that ambient brightness changes determines object, and
Corresponding operation response is executed according to the motion track controlling electronic devices, is partially referred to so that the recognizer of image need to only utilize
Show that the pixel intensity signal there are ambient brightness variation is calculated to obtain the profile of image, algorithm is relatively simple, reduces
To the consumption of hardware resource in algorithm operational process, the power consumption of electronic equipment is thereby reduced.
In some embodiments, referring to Fig. 3, showing determining object motion track provided by the embodiments of the present application in figure

For example, as shown in Fig. 2, analyzed by the position to the object pixel coordinate in array of figure, it can substantially really
The profile of the fixed object is circular object.
202, the change in location situation of the profile at least two periods is determined.
Wherein, the change in location situation may include the parameters such as the direction of displacement of object, distance.
Specifically, as shown in Fig. 2, by the array of figure B1 in the T1 period, the array of figure B2 with the T2 period can pass through
In the contour of object that the T1 period is formed to the object pixel coordinate between the T2 period, to determine the change in location situation of object.
For example, as shown in Fig. 2, can determine the circular center location, only after the profile for determining the object is round
The T1 period is compared with the center location of the profile of T2 period, the T1 period can be obtained to the profile between the T2 period
Change in location situation.
203, the motion track of object is determined according to change in location situation.
As shown in Fig. 2, because the profile for the object that the object pixel coordinate is formed and the shape of object have corresponding relationship,
By analyzing the change in location situation of T1 period to the profile between the T2 period, the motion track of object can be determined simultaneously.
From the foregoing, it will be observed that the profile of object is obtained by the object pixel coordinate of the same period, using determining at least two
The change in location situation of profile in a period can determine the motion track of object according to the change in location situation, thus logical

In some embodiments, the object pixel that the photosensitive sub-pixel of brightness change is generated in the same period can be sat
Mark, is arranged according to the pixel array position of light sensor, to obtain the array of object pixel coordinate as shown in Figure 2
Figure.
After obtaining the array of figure of object pixel coordinate, object can be formed according to the positional relationship of object pixel coordinate
Profile.Specifically, becoming because the edge placement of object is easy the moving influence by object to generate brightness in a short time
Change, therefore by the position of analysis object pixel coordinate, the general profile of object can be calculated by algorithm.
For example, as shown in Fig. 2, analyzed by the position to the object pixel coordinate in array of figure, it can substantially really
The profile of the fixed object is circular object.
302, object identification is carried out to profile, to determine the thingness of profile.
Wherein, the thingness can refer to the type of object, such as football, the hand etc. of human body.
It is analyzed by the position to the object pixel coordinate in array of figure, can use algorithm and object is carried out to the profile
Body identification, determines the thingness of the object.
For example, being sat if what is streaked before light sensor is the hand of human body by the object pixel to the same period
It marks after corresponding array of figure analyzed, the profile of available hand.Image recognition is carried out you can learn that the object to the profile
Body is the hand of human body.
303, whether the corresponding object of judgment object attribute is target object；If so, according at least two periods
The change in location of profile determine the motion track of object；If it is not, then terminating to respond.
If preset target object is the hand of human body, only works as thingness corresponding to the profile detected and behave
When the hand of body, the step that the motion track of object is determined according to the change in location of the profile at least two periods is just executed
Suddenly.If there are other objects to streak light sensor, it is not responding to.So it can reduce and accidentally respond to avoid the interference of other objects
Number, to further decrease the power consumption of electronic equipment.
304, the motion track of object is determined according to the change in location of the profile at least two periods.
As shown in Fig. 2, because the profile for the object that the object pixel coordinate is formed and the shape of object have corresponding relationship,
By analyzing the change in location situation of T1 period to the profile between the T2 period, the motion track of object can be determined simultaneously.
From the foregoing, it will be observed that the program improves processing in the operand for further mitigating algorithm relative to the scheme in Fig. 3
Efficiency, to can also only identified by carrying out object identification to the profile under the premise of reducing the power consumption of electronic equipment
At the profile be target object when, just execution step.Which it is possible to prevente effectively from other objects interference, reduce accidentally respond time
Number, to further decrease the power consumption of electronic equipment.

Type can according to the actual situation depending on.
In some embodiments, the difference between two signal parameters can be calculated, whether default threshold is greater than by difference
Value determines whether to meet preset condition.
For example, for example, the pixel intensity at the second moment is believed if the voltage value of the pixel intensity signal at the first moment is 0.3V
Number voltage value be 0.5V, then compared, then may be used by voltage value of the processor to the pixel intensity signal at two moment
To determine that the difference of the pixel intensity signal at two moment is 0.2V, if preset threshold is 0.1V, the two can be determined
Difference between the signal parameter of pixel intensity signal is greater than preset threshold, to meet preset condition.
If meeting the preset condition, the pixel intensity that the photosensitive sub-pixel is got at least two moment is defined
There are ambient brightness variations for signal designation.
If 403, meeting preset condition between signal parameter, variable signal corresponding with photosensitive sub-pixel is generated, otherwise
It does not generate.
Wherein, variable signal is used to indicate the pixel intensity signal designation that photosensitive sub-pixel is got at least two moment
There are ambient brightness variations.The variable signal can be some algebra or some signal parameter.
If being unsatisfactory for preset condition between the signal parameter, the variable signal is not generated, avoids excessive information parameter
The calculation amount for increasing algorithm, to further increase computational efficiency.
The brightness change if it exists, then according to the instruction, there are the pixel intensity signals that ambient brightness changes to determine object
The motion track of body may include:
404, according to variable signal, the object pixel coordinate of the corresponding photosensitive sub-pixel of variable signal is determined.
In some embodiments, in order to which the mistake response times for reducing electronic equipment determine variable signal according to variable signal
The object pixel coordinate of corresponding photosensitive sub-pixel, comprising:
Judge whether the photosensitive sub-pixel quantity for generating variable signal meets preset trigger condition；
If so, determining the object pixel coordinate of the corresponding photosensitive sub-pixel of variable signal；
If it is not, not responded to the variable signal of generation then.
Wherein, preset trigger condition can be triggered according to the quantity of photosensitive sub-pixel.
For example, if the preset trigger condition of setting are as follows: there is the corresponding photosensitive sub-pixel of more than 100 variable signals.Then
Only when the mobile range of object is larger and makes the quantity of the corresponding photosensitive sub-pixel of the variable signal generated in the same period
When greater than 100, the object pixel coordinate of the corresponding photosensitive sub-pixel of variable signal is just determined.
Accidentally response times can be so further avoided, to more further reduce the power consumption of electronic equipment.
From the foregoing, it will be observed that just thinking that meeting preset condition between signal parameter just generates variable signal, and according to the variable signal
It determines object pixel coordinate, can effectively improve computational efficiency, reduce the power consumption of electronic equipment.
