Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
Referring to fig. 1 and fig. 2 together, the control method according to the embodiment of the invention can be applied to an electronic device 100. The electronic device 100 includes an iris recognition module 20, and the iris recognition module 20 includes an infrared light source 22 and an infrared camera 24. The control method comprises the following steps:
s31: controlling the infrared light source 22 to emit infrared light at a first power;
s32: controlling the infrared camera 24 to collect images;
s33: processing the image to identify iris information; and
s35: and controlling the infrared light source 22 to emit infrared light at a second power when the iris information meets the preset condition, wherein the second power is greater than the first power.
Referring to fig. 2 again, the electronic device 100 according to the embodiment of the invention includes an iris recognition module 20 and a processor 30. The iris recognition module 20 includes an infrared light source 22 and an infrared camera 24. The processor 30 is configured to:
controlling the infrared light source 22 to emit infrared light at a first power;
controlling the infrared camera 24 to collect images;
processing the image to identify iris information; and
and controlling the infrared light source 22 to emit infrared light at a second power when the iris information meets the preset condition, wherein the second power is greater than the first power.
That is, the control method of the embodiment of the present invention may be implemented by the electronic apparatus 100 of the embodiment of the present invention, wherein the steps S31, S32, S33, S34 and S35 may be implemented by the processor 30.
The electronic device 100 of the present embodiment includes an infrared light source 22, an infrared camera 24, and a processor 30. The infrared camera 24 is used for collecting iris images, and the infrared light source 22 is used for emitting infrared light with first power to supplement light for the infrared camera 24. The processor 30 is configured to drive the infrared light source 22 to emit infrared light at a second power greater than the first power for iris recognition when the iris image reaches a preset condition.
The control method and the electronic device 100 according to the embodiment of the present invention adjust the power of the infrared light source 22 according to the image collected by the infrared camera 24, thereby reducing the power consumption of the infrared light source 22 and avoiding the infrared light source 22 from generating heat.
In certain embodiments, infrared light source 22 refers to a light source capable of producing infrared radiation (infrared light), which is a range of electromagnetic radiation having wavelengths greater than the wavelength of red light.
In some embodiments, the iris information may include information of the iris region and/or information of the iris position, that is, the iris information may include information of the iris region, information of the iris position, information of the iris region, and information of the iris position. The preset condition may be a suitable iris distance. Therefore, the iris distance can be acquired by utilizing the iris information, and whether the iris information meets the preset condition or not can be judged according to whether the iris distance is proper or not.
Specifically, the information of the iris region may include information of an area of the iris region, and when the area of the iris region is appropriate, it is determined that the iris distance is appropriate, that is, it is determined that the iris information meets a preset condition; and judging that the iris distance is not appropriate when the area of the iris area is not appropriate, namely determining that the iris information does not conform to the preset condition. The information of the iris position may refer to a position relationship between the iris and the electronic device 100 or the iris recognition module 20, and the iris distance may be obtained through the position relationship between the iris and the electronic device 100 (such as the iris recognition module 20), so as to obtain the iris distance according to the iris position information, and determine whether the iris information meets a preset condition according to the iris distance.
In some embodiments, the iris distance may refer to a distance between an iris region (or eye) of the user and the electronic device 100 (e.g., the iris recognition module 20). It is understood that when there is only one iris region, i.e. the image includes only one iris region corresponding to one eye, the iris distance may refer to the distance between the iris region or the eye and the electronic device 100; when there are a plurality of iris regions, that is, when there are a plurality of iris regions corresponding to a plurality of eyes, the iris distance may be an average value of distances between the plurality of iris regions and the electronic device 100, a minimum value of the distances between the plurality of iris regions and the electronic device 100, or a maximum value of the distances between the plurality of iris regions and the electronic device 100, and is not particularly limited herein.
It can be understood that, in the process of identifying the iris by the electronic device 100, when the distance between the irises is too large, the iris area of the image acquired by the electronic device 100 is too small, which may result in that the texture information of the iris cannot be extracted and thus the iris identification cannot be performed; when the iris distance is too small, texture information of the iris included in the image may be incomplete, resulting in failure to perform iris recognition. Therefore, the power of the infrared light source 22 can be adjusted from the first power to the second power when the iris distance is timely switched, that is, when the iris information meets the preset condition, so that the infrared light source 22 emitting infrared light with the second power is used for displaying the texture information of the iris, and the infrared camera 24 is used for imaging to obtain the iris image. When the iris distance is not appropriate, i.e., the iris information is not in condition, the infrared light source 22 is kept emitting infrared light at the first power to avoid unnecessary power consumption and heating problems for the electronic device 100.
It can be understood that, in the embodiment of the present invention, the image is used to identify the iris information to determine whether the iris information meets the preset condition according to the iris information, and the requirement on the quality (such as color, resolution, etc.) of the image is not high, so that the infrared light source 22 with the first power can be used to assist the infrared camera 24 to acquire the image (gray image), so as to acquire the iris information by using the image acquired by the infrared camera 24, and then determine whether the iris information meets the preset condition according to the iris information, such as acquiring the iris distance according to the iris information, and then determine whether the iris distance is proper.
In some embodiments, the iris distance may range from 10 cm to 30 cm, i.e., when the iris distance is between 10 cm and 30 cm, the iris distance is deemed appropriate; when the iris distance is less than or equal to 10 cm or more than or equal to 30 cm, the iris distance is not appropriate.
In some embodiments, the electronic device 100 comprises a cell phone, a laptop, a tablet, a smart watch, or smart glasses. In the embodiment of the present invention, the electronic device 100 is a mobile phone.
Referring to fig. 3, in some embodiments, the control method includes the following steps:
s36: judging whether an iris identification request is received or not;
s37: when receiving the iris recognition request, the process proceeds to step S31; and
s38: and returns to step S36 when the iris recognition request is not received.
Referring again to fig. 2, in some embodiments, the processor 30 is configured to:
judging whether an iris identification request is received or not;
entering a step of controlling the infrared light source 22 to emit infrared light at a first power upon receipt of the iris recognition request; and
and returning to the step of judging whether the iris identification request is received or not when the iris identification request is not received.
That is, steps S36, S37, and S38 may be implemented by the processor 30.
In this way, the steps or processes related to iris recognition can be executed only when the iris recognition request is received, thereby reducing the power consumption of the electronic device 100.
Specifically, the processor 30 first determines whether the electronic device 100 receives an iris recognition request, and executes relevant steps or procedures for iris recognition when receiving the iris recognition request; when the iris recognition request is not received, the electronic device 100 does not execute the steps or procedures related to the iris recognition, but continuously determines whether the iris recognition request is received, thereby preventing the electronic device 100 from executing the steps or procedures related to the iris recognition all the time, further reducing the power consumption of the electronic device 100, and improving the cruising ability of the electronic device 100.
Referring to fig. 4 and 5 together, in some embodiments, the electronic device 100 includes an acceleration sensor 40. Step S36 includes the following steps:
s362: processing an output signal of the acceleration sensor 40 to determine whether the electronic device 100 is operating in a predetermined manner; and
s364: it is determined that an iris recognition request is received while the electronic device 100 operates in a predetermined manner.
Referring again to fig. 5, in some embodiments, the electronic device 100 includes an acceleration sensor 40. The processor 30 is configured to:
processing an output signal of the acceleration sensor 40 to determine whether the electronic device 100 is operating in a predetermined manner; and
it is determined that an iris recognition request is received while the electronic device 100 operates in a predetermined manner.
That is, steps S362 and S364 may be implemented by the processor 30.
In this way, whether the electronic device 100 receives the iris recognition request can be determined by the acceleration sensor 40, so that the operation procedure of the user is simplified, and the user can use the electronic device 100 conveniently.
Specifically, the acceleration sensor 40 may be configured to detect an acceleration of the electronic device 100, and the processor 30 obtains an output signal of the acceleration sensor 40 (e.g., the acceleration detected by the acceleration sensor 40) to obtain an operation mode of the electronic device 100, determines whether the electronic device 100 is operated in a predetermined manner, and determines that an iris recognition request is received when the electronic device 100 is operated in the predetermined manner. In one embodiment, the predetermined manner is a left-right translation two passes within 2 seconds, the acceleration sensor 40 detects the acceleration of the electronic device 100, and when the direction in which the acceleration of the electronic device 100 is detected is left, left to right, right to left, left to right within 2 seconds, it is determined that the electronic device 100 is operating in the predetermined manner, thereby determining that the electronic device 100 has received the iris recognition request. It should be noted that the processor 30 may determine the motion trajectory of the electronic device 100 by processing the acceleration of the electronic device 100 acquired by the acceleration sensor 40, and the predetermined manner may also refer to a predetermined motion trajectory, such as an arc, a circle, a V, and the like. For example, when the user picks up the electronic apparatus 100, the electronic apparatus 100 moves from a position away from the face of the user to a position close to the face of the user, during which the motion trajectory of the electronic apparatus 100 is generally arc-shaped, so that the predetermined manner may be set as arc-shaped, and whether the motion trajectory of the electronic apparatus 100 is arc-shaped is determined by determining whether the motion trajectory of the electronic apparatus 100 is arc-shaped according to the acceleration of the electronic apparatus 100 acquired by the acceleration sensor 40.
Referring to fig. 6, in some embodiments, the electronic device 100 includes a housing 60, the housing 60 includes a front surface 62, and the iris recognition module 20 is disposed in the housing 60 and exposed from the front surface 62.
In this way, the housing 60 of the electronic device 100 can be used to protect the iris recognition module 20 and facilitate the operation of the iris recognition module 20.
Specifically, the iris recognition module 20 is disposed in the housing 60, and the housing 60 can be used for protecting the iris recognition module 20 against dust and water, so as to prevent the iris recognition module 20 from being damaged by external factors and affecting normal operation of the iris recognition module. In addition, expose iris identification module 20 from front surface 62 and can make things convenient for iris identification module 20 to carry out work, avoid influencing infrared camera 24 acquisition light of iris identification module 20 to ensure that iris identification module 20 can high-efficient work.
Referring to FIG. 7, in some embodiments, the illumination range of infrared source 22 and the field of view of infrared camera 24 at least partially overlap.
In this manner, infrared light source 22 and infrared camera 24 may work in concert.
Specifically, the infrared light source 22 and the infrared camera 24 need to cooperate to acquire an iris image, the infrared light source 22 and the infrared camera 24 may be disposed on the same side of the electronic device 100, and the infrared light source 22 and the infrared camera 24 are disposed adjacent to each other, so that the infrared light emitted by the infrared light source 22 passes through the surface of the object and then can be acquired by the infrared camera 24. For example, the infrared light source 22 and the infrared camera 24 with the first power may be used to acquire images, so as to determine the iris distance according to the images, adjust the power of the infrared light source 22 to the second power when the iris distance is in a clutch state, and further obtain the iris image by using the infrared light source 22 and the infrared camera 24 with the second power.
Referring to fig. 8, in some embodiments, step S31 includes the following steps:
s312: controlling the infrared light source 22 to emit infrared light at a first power with a pulse signal of a first duty cycle;
step S35 includes the following steps:
s351: the pulse signal at a second duty cycle controls the infrared light source 22 to emit infrared light at a second power, the second duty cycle being greater than the first duty cycle.
Referring again to fig. 2, in some embodiments, the processor 30 is configured to:
controlling the infrared light source 22 to emit infrared light at a first power with a pulse signal of a first duty cycle;
the pulse signal at a second duty cycle controls the infrared light source 22 to emit infrared light at a second power, the second duty cycle being greater than the first duty cycle.
That is, steps S312 and S351 may be implemented by the processor 30.
In this way, the infrared light source 22 can be controlled to emit infrared light at different powers by the pulse signal of the infrared light source 22.
Specifically, the processor 30 may first determine at which power the infrared light source 22 is to emit infrared light according to the infrared camera 24, then generate a corresponding pulse signal, and then control the infrared light source 22 to emit infrared light at different powers by using the pulse signal.
It will be appreciated that when infrared light source 22 emits infrared light at a first power, the duty cycle of the pulsed signal is relatively small; when the infrared light source 22 emits infrared light at the second power, the duty ratio of the pulse signal is relatively large. In one embodiment, when infrared light source 22 emits infrared light at a first power, the duty cycle of the pulse signal is 50%; when the infrared light source 22 emits infrared light at the second power, the duty ratio of the pulse signal is 100%.
Referring to fig. 9, in some embodiments, step S33 includes the following steps:
s332: processing the image to identify whether a face is present;
s334: identifying iris information when a face exists; and
s336: and returning to the step S31 when no human face exists.
Referring again to fig. 2, in some embodiments, the processor 30 is configured to:
processing the image to identify whether a face is present;
identifying iris information when a face exists; and
and returning to the step of controlling the infrared light source 22 to emit infrared light at the first power when the human face is not present.
That is, steps S332, S334, and S336 may be implemented by the processor 30.
Thus, the calculation amount of the processor 30 can be reduced, and the work efficiency of the electronic device 100 can be improved.
Specifically, the iris recognition information is generally performed by face recognition first, and thus the amount of calculation for iris recognition is generally greater than that for face recognition. Therefore, the image can be rapidly processed through the face recognition technology to recognize whether the face exists in the image or not, when the face exists, the image possibly contains iris information, and then the iris information is recognized and the iris distance can be judged through the iris information; when no human face exists, the image does not contain the iris information, and the image can be directly acquired again without carrying out iris information recognition on the image, so that the unnecessary calculation amount of the processor 30 is reduced, and the working efficiency of the electronic device 100 is improved.
Referring to fig. 10, in some embodiments, step S334 includes the following steps:
s3342: the infrared light source 22 is controlled to emit infrared light at a third power, which is less than the second power and greater than the first power.
Referring again to fig. 2, in some embodiments, the processor 30 is configured to:
the infrared light source 22 is controlled to emit infrared light at a third power, which is less than the second power and greater than the first power.
That is, step S3342 may be implemented by the processor 30.
In this way, the infrared light source 22 can be controlled to emit infrared light at the third power to obtain a clearer image when a human face is present.
It can be understood that the identification of the iris information requires an image with relatively high definition, and the definition of the image is relatively low in the face identification. Therefore, the images acquired by the infrared light source 22 and the infrared camera 24 with the first power can be used for face recognition, after a face is recognized, since subsequent iris information recognition requires an image with higher definition, in order to improve iris information recognition efficiency, the power of the infrared light source 22 may be controlled to be adjusted to the third power, the image including the face is acquired again by the infrared light source 22 and the infrared camera 24 with the third power, and then iris information recognition is performed on the image.
It should be noted that the infrared light source 22 using the third power is used for improving the recognition efficiency, and in some embodiments, the infrared light source 22 using the first power can also recognize the iris information, and is not particularly limited herein. Further, the infrared light source 22 may be controlled to emit infrared light at the third power using the pulse signal described above. In one embodiment, the duty cycle of the pulse signal corresponding to the infrared light source 22 of the third power is 80%.
Referring to fig. 11, in some embodiments, the iris information includes information of an iris region, and the step S35 includes the steps of:
s352: judging whether the area of the iris area is larger than a first preset value and smaller than a second preset value;
s354: determining that the iris information meets a preset condition when the area of the iris area is larger than a first preset value and smaller than a second preset value; and
s356: and when the area of the iris area is less than or equal to a first preset value or greater than or equal to a second preset value, determining that the iris information does not meet the preset condition.
Referring again to fig. 2, in some embodiments, the iris information includes information of an iris region, and the processor 30 is configured to:
judging whether the area of the iris area is larger than a first preset value and smaller than a second preset value;
when the area of the iris area is larger than a first preset value and smaller than a second preset value, determining that the iris information meets a preset condition; and
and when the area of the iris area is less than or equal to a first preset value or greater than or equal to a second preset value, determining that the iris information does not meet the preset condition.
That is, steps S352, S354, and S356 may be implemented by the processor 30.
Therefore, whether the iris information meets the preset condition or not can be judged quickly and accurately according to the area of the iris area.
It is understood that a smaller iris area indicates that the iris is far from the electronic device 100, i.e., the iris distance is larger; when the iris area is relatively large, the iris is close to the electronic device 100, that is, the iris distance is relatively small, so that whether the iris distance is proper or not can be determined by judging the area of the iris area, and whether the iris information meets the preset condition or not is determined. Specifically, the first predetermined value is smaller than the second predetermined value, and when the area of the iris area is larger than the first predetermined value and smaller than the second predetermined value, the iris distance is determined to be appropriate, that is, the iris information is determined to meet the preset condition, and the obtained iris image texture information is clear and complete; when the area of the iris area is smaller than or equal to a first preset value, the iris distance is too small, namely the iris information is determined to be not in accordance with the preset condition, and the obtained iris image may be incomplete; when the area of the iris area is larger than or equal to the second preset value, the iris distance is too large, namely the iris information is determined to be not in accordance with the preset condition, and at the moment, the obtained texture information of the iris image is possibly fuzzy.
In some embodiments, the values of the first predetermined value and the second predetermined value may be obtained through experiments and preset in the electronic device 100 before the electronic device 100 is shipped from a factory, and different electronic devices 100 may have different first predetermined values and second predetermined values according to different imaging capabilities. The area of the iris region may refer to the area of pixels occupied by the iris region, and in one embodiment, when the area of pixels occupied by the iris region is 100 × 100, that is, when the iris region is formed of 10000 pixels, the corresponding iris distance is preferably set.
Referring to fig. 12, an electronic device 100 according to an embodiment of the invention includes an iris recognition module 20, one or more processors 30, a memory 70, and one or more programs. Where one or more programs are stored in the memory 70 and configured for execution by the one or more processors 30, the programs being for executing the instructions of the control method of any of the above embodiments of the invention.
As an example, the program may be instructions for executing the following control method:
s31: controlling the infrared light source 22 to emit infrared light at a first power;
s32: controlling the infrared camera 24 to collect images;
s33: processing the image to identify iris information; and
s35: and controlling the infrared light source 22 to emit infrared light at a second power when the iris information meets the preset condition, wherein the second power is greater than the first power.
Referring to fig. 13, a computer readable storage medium 800 according to an embodiment of the present invention includes a computer program for use with the electronic device 100, and the computer program is executable by the processor 30 to perform the control method according to any of the above embodiments of the present invention.
As one example, a computer program may be executed by the processor 30 to perform the following control method:
s31: controlling the infrared light source 22 to emit infrared light at a first power;
s32: controlling the infrared camera 24 to collect images;
s33: processing the image to identify iris information; and
s35: and controlling the infrared light source 22 to emit infrared light at a second power when the iris information meets the preset condition, wherein the second power is greater than the first power.
Note that the computer-readable storage medium 800 may be a storage medium built in the electronic apparatus 100, or may be a storage medium that can be inserted into and removed from the electronic apparatus 100.
