It should be understood that the above general description and detailed description below are exemplary and explanatory and not intended to limit the present disclosure.
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The methods, devices, systems, and other features discussed below may be embodied in a number of different forms.

Executable instructions of the processor 120 are stored in the memory 140. The processor may execute the instructions to control the mobile terminal 100, and in particular the FIM 160 to implement any of the features described herein.
The fingerprint identification module 160 may also be referred to as a fingerprint identification sensor. The fingerprint identification module 160 as described with relation to
With reference to flow chart 200, at least two frames of fingerprint images may be captured by an image capturing device (202). The fingerprint images may correspond to a same finger. Although reference is made to capturing images of a user's fingerprint, in alternatively embodiments the fingerprint identification module 160 may be configured to capture images of other objects that include identifiable attributes (e.g., stylus pen or other pointer tool), and implement any of the features described herein based on the object images.
As described, the fingerprint identification module 160 may include an image capturing device capable of acquiring a fingerprint image. The fingerprint identification module 160 may be configured to capture an image based on command inputs provided to the corresponding mobile terminal 100. Optionally, when a finger is placed in an identification area of the fingerprint identification module, the fingerprint identification module 160 may acquire the fingerprint images by capturing each fingerprint image according to a predetermined time interval. Each fingerprint frame referenced herein may correspond to a separate captured image.
With reference to flow chart 200, position change information describing the fingerprint moving on the identification area of the fingerprint identification module 160 may be determined according to the at least two frames of fingerprint images captured by the fingerprint identification module 160 (204).
If the finger translates, rotates, or otherwise moves to different positions on the identification area of the fingerprint identification module 160, the fingerprint image of the finger may also change such that two or more fingerprint images (frames) may be captured. The position change information of the fingerprint may be calculated by virtue of the at least two frames of fingerprint images which are sequentially acquired.
With reference to flow chart 200, an operational instruction may be generated according to the position change information (206). The operational instruction may be interpreted by the mobile terminal 100 to implement a translation instruction for moving an object (e.g., pointer object) displayed on a graphical interface of the mobile terminal, a rotation instruction for rotating a selected object (e.g., selected image) displayed on a graphical interface of the mobile terminal 100, or another operational function on the mobile terminal 100. It follows that the fingerprint identification module 160 may be re-purposed on the mobile terminal 100 to be utilized similar to a tracking pad or other navigational tool on the mobile terminal 100.
According to some embodiments, the operational instruction may be referenced by the processor 120 of the mobile terminal 100 to control an operation object. The operation object may be a user interface element displayed on a display screen or hardware of the mobile terminal 100. Other types of operation objects are also contemplated in other embodiments of the present disclosure.
In view of the above, different position information of the same fingerprint may be obtained from two or more fingerprint images. The position information may then be analyzed to obtain the corresponding position change information to generate the corresponding operational instruction, and the operational instruction may be configured to implement an operational function on the corresponding mobile terminal. For example, the operational instruction may implement the operational function to control movement of an operation object displayed on the corresponding mobile terminal. This way, the fingerprint identification module 160 may further be utilized to generate an operational instruction based on a movement of a finger on the identification area, where the operational instruction may be referenced to implement an operational function on the mobile terminal (e.g., a translation operation or a rotation operation on an object).
With reference to flow chart 300, at least two frames of fingerprint images of the same fingerprint may be acquired (301).
According to some embodiments, the fingerprint identification module may acquire the frames of fingerprint images at predetermined time intervals.
According to some embodiments, the fingerprint identification module further includes a contact sensing device, where the contact sensing device may detect whether a finger of a user contacts the fingerprint identification module. When the contact sensing device detects the finger of the user contacting the fingerprint identification module, the fingerprint identification module may be allowed to acquire the fingerprint frames by capturing images of the fingerprints. The images may be captured according to the predetermined time interval. When the contact sensing device stops detecting the finger of the user contacting the fingerprint identification module, the fingerprint identification module may stop acquiring the fingerprint frames.
For the same fingerprint, the fingerprint identification module may acquire a sequence of fingerprint images, the sequence of fingerprint images may include multiple frames of fingerprint images which are sequentially arranged. If the finger of the user translates, rotates, or otherwise moves on the fingerprint identification module, the fingerprint images in the sequence of fingerprint images may reflect such a movement.
With reference to flow chart 300, n characteristic areas in the ith frame of fingerprint image may be acquired, where i is a positive integer and n is also a positive integer (302).
The sequence of fingerprint images may include the multiple frames of fingerprint images which are sequentially arranged. According to some embodiments, the fingerprint identification module may analyze a position change through two adjacent frames of fingerprint images. First, the fingerprint identification module acquires n characteristic areas in the ith frame of fingerprint images. Each characteristic area may be an area including x*y pixels, where values of x and y depend on requirements on a calculation capability and identification accuracy of the fingerprint identification module. Generally, each characteristic area may have the same size, but may also have different sizes.
With respect to whether the characteristic areas are predetermined or dynamically selected, any one of the following two implementation manners may be adopted.
For example n characteristic areas in the ith frame of fingerprint image may be acquired according to n predetermined area positions.
In this implementation, the n area positions may be predetermined, and when the finger of the user is placed on the fingerprint identification area, local images of the fingerprint image in n areas are acquired as the n characteristic areas.
In another example, n characteristic areas may be acquired from the ith frame of a fingerprint image according to a predetermined condition, wherein the predetermined condition comprises at least one of the following: an image quality definition is higher than a first threshold value, an image contrast is higher than a second threshold value, a local image characteristic is consistent with a predetermined characteristic, or the current area is a matched area relative to a reference area in the previous frame of the fingerprint image.
In this implementation, the n area positions are not predetermined, and the n characteristic areas are dynamically selected according to the ith frame of fingerprint image obtained by placing the finger of the user in the fingerprint identification area.
As shown in exemplary fingerprint frame 430 illustrated in
Similarly, the fingerprint identification module may also select the characteristic areas according to at least one of following: the image contrast is higher than the second threshold value, the local image characteristic is consistent with the predetermined characteristic and the current area is the matched area relative to the reference area in the previous frame of fingerprint image.
With reference to flow chart 300, the (i+1)th frame of the fingerprint images may be analyzed and searched for matched areas that match up with the n characteristic areas, respectively (303).
For example, for a given characteristic area, if the characteristic area is determined to have moved in the (i+1)th frame of the fingerprint images, the matched area of the characteristic area may be found in the (i+1)th frame of the fingerprint images by virtue of a motion object detection technology.
A similarity between each characteristic area and the corresponding matched area detected from subsequent fingerprint frames may be represented by, for example, a parameter such as a Hadamard Absolute Difference (HAD), a Sum of Absolute Difference (SAD) and a Sum of Absolute Transformed Difference (SATD). That is, for each characteristic area, the matched area may be found in the (i+1)th frame of fingerprint images.
For example, as shown in exemplary second fingerprint frame 450 corresponding to a second fingerprint image of the user's finger in
With reference to flow chart 300, for each characteristic area corresponding to the first fingerprint frame 420, a difference in location and/or direction between the characteristic areas and the corresponding matched areas may be determined (304). For example, a motion vector of the characteristic area may be calculated according to the characteristic areas and the corresponding matched areas.
The fingerprint identification module may calculate the motion vectors between the characteristic areas and the corresponding matched areas as determined from the two fingerprint frames including the two fingerprint images, first fingerprint frame 420 and second fingerprint frame 450, respectively. In particular, the fingerprint identification module may calculate the motion vectors between the characteristic areas and the corresponding matched areas according to position information of the characteristic areas and the corresponding matched areas, where the motion vectors may include a motion direction and a motion distance between the characteristic areas and the corresponding matched areas, which represents a movement of the user's finger on the fingerprint identification area 30.
As shown in exemplary characteristic area map 460 illustrated in
With reference to flow chart 300, the motion vectors of the n characteristic areas may be determined as position change information of the fingerprint as the movement of the fingerprint is detected from each subsequent fingerprint frame (305).
As shown by characteristic area map 460, the fingerprint identification module calculates the motion vectors of the characteristic areas 31, 32, 33, and 34 determined from the first fingerprint frame 420, and determines the four motion vectors as the position change information of the fingerprint as it moves.
The motion vector 31a indicates that the characteristic area 31 translates leftwards by 2 units, the motion vector 32b indicates that the characteristic area 32 translates leftwards by 2 units, the motion vector 33c indicates that the characteristic area 33 translates leftwards by 2 units and the motion vector 34d indicates that the characteristic area 34 translates leftwards by 2 units.
With reference to flow chart 300, an operational instruction (e.g., a translation instruction) according to the n motion vectors may be generated when motion directions of the n motion vectors are determined to be the same (306).
As shown by characteristic area map 460, the directions of the 4 motion vectors are the same, are directed leftward, and the motion distances are all 2 units. Based at least on these factors, the fingerprint identification module may generate the translation instruction. The translation instruction contains a translation direction and a translation distance, e.g., information indicating that the motion direction is leftward and the motion distance is 2 units.
According to some embodiments, the fingerprint identification module may transmit the generated translation instruction to a Central Processing Unit (CPU) (e.g., processor 120 of mobile terminal 100), and the CPU may control the operation object displayed on the mobile terminal to translate leftwards by 2 units according to the translation instruction.
With reference to flow chart 300, when n is more than or equal to 2 and the motion directions of the n motion vectors are different, a rotation direction and a rotation angle may be determined according to the n motion vectors (307).
According to some embodiments, when the directions of the n motion vectors are inconsistent, the rotation direction and the rotation angle may be determined to generate another operational instruction according to the motion vectors.
According to some embodiments, the process described at (307) may comprise two or more sub-processes as described by flow chart 500 that describes exemplary logic that may be implemented according to the process described at (307).
For instance, the process described at (307) may include determining a rotating center point of one or more characteristic areas according to a perpendicular bisector corresponding to each of the n motion vectors (307a).
The fingerprint identification module may determine the rotating center point according to the perpendicular bisector corresponding to each calculated motion vector.
For example, as shown in exemplary characteristic area map 470 illustrated in
The process described at (307) may further include determining a rotation direction and a rotation angle for rotating an operation object according to the directions of the n motion vectors and the rotating center point (307b).
The fingerprint identification module may determine the rotation direction according to the direction of any motion vector relative to the rotating center point 50. The fingerprint identification module may determine the rotation angle according to determined included angles between connecting lines of a starting point and ending point of any motion vector crossing through with the rotating center point 50.
As shown in exemplary characteristic area map 480 illustrated in
With reference to flow chart 300, a rotation instruction may be generated according to the rotation direction and the rotation angle (308).
The fingerprint identification module may generate the rotation instruction, or another operational instruction (e.g., parallel movement instruction based on two touch points moving in parallel, sliding instruction based on a touch point moving across a touch screen, sliding acceleration instruction based on an acceleration of a moving touch point across a touch screen), according to the calculated rotation direction and rotation angle, where the rotation instruction includes the rotation direction and the rotation angle.
According to some embodiments, the fingerprint identification module may transmit the generated rotation instruction to the connected CPU, and the CPU may control the operation object to rotate clockwise by 90 degrees according to the rotation instruction.
In view of the above, according to the instruction generation process described by flow chart 300, different position information corresponding to the tracking of movement of a user's finger (or other detectable object) as captured by fingerprint images included in fingerprint frames, is analyzed to obtain the corresponding position change information to form the corresponding operational instruction, where and the operational instruction may be configured to implement a translation control or a rotation control over the operation object, so that the fingerprint identification module may be repurposed to achieve additional features on the mobile terminal. It follows that the fingerprint identification module may be utilized to generate the operational instruction for controlling a translation operation, a rotation operation, or some other movement-based operational control for controlling movement of the operation object on the mobile terminal.
According to the disclosed instruction generation process, the translation operation and rotation operation applied to control the operation object may further be distinguished according to whether the motion directions of the multiple motion vectors are the same or different, and the translation instruction or the rotation instruction may be calculated by virtue of the motion vectors formed by the n characteristic areas and the matched areas, so that identifying the type of operational instruction to implement based on the user's finger movement as detected from the captured fingerprint images may be achieved.
When the finger of the user moves, for example, in the identification area 30 of the fingerprint identification module, the fingerprint identification module may acquire six fingerprint frames including fingerprint images, acquire four characteristic areas in the first fingerprint frame 420 that includes the first fingerprint image, analyze the second fingerprint frame 450 that includes the fingerprint image that captures a movement of the user's finger and identify four matched areas matched with the characteristic areas respectively, calculate motion vectors for the four characteristic areas based on a difference of the characteristic areas and the matched areas, determine the position change information of the fingerprint according to the motion vectors, and generate the corresponding operational instruction. After the operational instruction is generated, the fingerprint identification module may store the four matched areas identified from the second fingerprint frame 450 as a current four characteristic areas, proceed to analyze a third fingerprint frame that includes a fingerprint image that captures a movement of the user's finger and identify four matched areas matched with the current characteristic areas respectively, and executes process (304) to process (308) after the matched areas are identified. Similarly, the fingerprint identification module may analyze the fourth, fifth and sixth fingerprint frames of fingerprint images for four corresponding matched areas respectively, and executes process (304) to process (308). It follows that the disclosed instruction generation process may be an iterative process that runs on subsequent fingerprint frames. Different position information of the same fingerprint in the fingerprint images may be analyzed to obtain the corresponding position change information to form the corresponding operational instruction, so that the effect of controlling the operation object on the mobile terminal may be achieved.
In another schematic example, due to movement of the finger, the originally selected characteristic areas may move off the identification area of the fingerprint identification module, which may cause a condition where the position change information of the fingerprint cannot be determined according to the motion vectors of the characteristic areas due to the characteristic areas no longer being detectable on the identification area. To address this situation, according to some embodiments the fingerprint identification module may be configured such that after the ith frame of fingerprint image is acquired, when i is an odd number, n characteristic areas may be selected for the ith frame of fingerprint image, the (i+1)th frame of fingerprint image may be analyzed to identify matched areas that match with the characteristic areas in the ith frame, the motion vectors of the characteristic areas may be calculated according to the characteristic areas and the matched areas, and the position change of the fingerprint may be determined according to the motion vectors, thereby generating the resulting operational instruction to implement control over the operation object.
For example, after acquiring six fingerprint frames including fingerprint images of the same fingerprint, the fingerprint identification module may be configured to analyze and select four characteristic areas from a first fingerprint frame and store the four characteristic areas. The fingerprint identification module may further be configured to analyze and select a second fingerprint frame for the matched areas matched with the characteristic areas, execute process (304) to process (308) after the matched areas are found, reselect characteristic areas from a third fingerprint frame after process (304) to process (308) are finished, search a fourth fingerprint frame for the matched areas, execute process (303) to process (308), and implement the same operation on the other fingerprint frames until the position change information of the fingerprint is determined. The characteristic areas and the matched areas may be continuously selected from the fingerprint images, so that the operational instruction may still be accurately generated to implement control over the operation object even when a certain fingerprint is not in the identification area is achieved.
It is important to note that the number n of the characteristic areas required by different operating instructions is different, the number n of the characteristic area required by the translation instruction is at least 1, and the number n of the characteristic areas required by the rotation instruction is at least 2.
It is important to note that, according to some embodiments the fingerprint identification module may acquires the fingerprint images and transmit the fingerprint images to a CPU or other processor of a mobile terminal in communication with the fingerprint identification module such that the CPU or other processor executes some or all of the processes described in flow chart 300. In particular, the CPU or other processor of the mobile terminal may be responsible for implementing process (302) to process (308).

The calculation module 720 may be configured to calculate position change information of the fingerprint according to the at least two frames of fingerprint images.
The instruction generation module 730 may be configured to generate an operational instruction according to the position change information, wherein the operational instruction may include a translation instruction and/or a rotation instruction.
In view of the above, different position information of the same fingerprint captured in the fingerprint images may be analyzed to obtain the corresponding position change information to generate the corresponding operational instruction. It follows that the fingerprint identification module may be configured to detect a user's finger movement and correlate the movement to an operational instruction (e.g., identifying a translation operation or a rotation operation) for controlling a movement of an operation object in the mobile terminal.

The characteristic acquisition sub-module 821 may be configured to acquire the n characteristic areas in the ith frame of fingerprint image according to n predetermined area positions. According to some embodiments, the characteristic acquisition sub-module 821 may be configured to acquire the n characteristic areas from the ith frame of fingerprint image according to a predetermined condition, where the predetermined condition may include at least one of the following: an image quality definition is higher than a first threshold value, an image contrast is higher than a second threshold value and a local image characteristic is consistent with a predetermined characteristic.
The instruction generation module 830 may include a first instruction sub-module 831, a second instruction sub-module 832, and a third instruction sub-module 833.

The second instruction sub-module 832 may be configured to, when n is more than or equal to 2 and the motion directions of the n motion vectors are different, determine a rotation direction and a rotation angle according to the n motion vectors.

It follows that the fingerprint identification module may be configured to detect a user's finger movement and correlate the movement to an operational instruction (e.g., identifying a translation operation or a rotation operation) for controlling a movement of an operation object in the mobile terminal.
According the translation operation and rotation operation of the user may be further distinguished according to whether the motion directions of the multiple motion vectors are the same or different, and the translation instruction or the rotation instruction is calculated by virtue of the motion vectors formed by the n characteristic areas and the matched areas, so that the effect of identifying a type of the operation of the user and further generating the corresponding operating instruction by virtue of the fingerprint identification module is achieved.
