Referring to Figures 1 and 2, the infrared light source assembly 100 of the embodiment of the present invention includes an infrared light source 10, a lens 20 and a driving assembly 30. The infrared light source 10 is used to emit infrared light. The lens 20 is arranged on the optical path of the infrared light source 10. The driving assembly 30 is used to drive the infrared light source 10 to move so that the lens 20 guides the infrared light to the target direction. Specifically, the lens 20 is arranged on the optical path of the infrared light source 10 and covers the optical path of the infrared light source 10, that is, the infrared light emitted by the infrared light source 10 can all be projected onto the lens 20. When the driving assembly 30 drives the infrared light source 10 to move, the lens 20 is always located on the optical path of the infrared light source 10 and covers the optical path, and the infrared light emitted by the infrared light source 10 can all be projected onto the lens 20. The movement of the infrared light source 10 can be rotation, movement (including translation and tilt movement), or both rotation and movement. The different relative positions of the infrared light source 10 and the lens 20 result in different emission directions of the infrared light guided by the lens 20. The driving component 30 can adjust the moving position of the infrared light source 10 according to the position of the target direction (for example, the eyes of the object to be identified), thereby adjusting the emission direction of the infrared light and enabling the lens 20 to guide the infrared light to the target direction.

The target direction may be the eyes of the object to be identified. When the lens 20 guides the infrared light to the target direction, the infrared light can cover the eyes of the object to be identified.

Of course, the drive assembly 30 can also be used to drive the lens 20 to move, so that the direction of the infrared light emitted by the infrared light source 10 after being projected by the lens 20 changes, thereby enabling the lens 20 to guide the infrared light to the target direction. Alternatively, the drive assembly 30 can also be used to drive the lens 20 and the infrared light source 10 to move, so that the direction of the infrared light emitted by the infrared light source 10 after being projected by the lens 20 changes, thereby enabling the lens 20 to guide the infrared light to the target direction.

Understandably, most people's irises are darker in color, requiring the use of an infrared light source 10 for fill-in illumination during iris image acquisition to obtain a clear iris image. However, many existing infrared light sources 10 utilize a surface light source to expand the coverage of the infrared light beam emitted by the infrared light source 10. This, on the one hand, results in higher power consumption by the infrared light source 10, and on the other hand, lower illumination intensity and less concentrated energy, resulting in poor fill-in illumination and, consequently, inability to obtain a high-quality iris image. The infrared light source assembly 100 of the present embodiment drives the infrared light source 10 and/or the lens 20 via the driving assembly 30 to change the direction of the infrared light emitted by the infrared light source 10 after passing through the lens 20, thereby enabling the lens 20 to direct the infrared light in the target direction. Consequently, even with a relatively low emission power, the infrared light source 10 can still project sufficiently strong infrared light onto the eyes of the subject to be identified. This reduces power consumption by the infrared light source 10, and on the other hand, the infrared light beam from the infrared light source 10 has more concentrated energy, a higher illumination intensity, and a better fill-in illumination effect.

Referring to FIG3 , an electronic device 200 according to an embodiment of the present invention includes a housing 202, an infrared camera 204, and an infrared light source assembly 100. The electronic device 200 includes a mobile phone, a tablet computer, a laptop computer, a smartwatch, a smart bracelet, smart glasses, a smart helmet, etc. In a specific embodiment of the present invention, the electronic device 200 is a mobile phone.

The infrared camera 204 and the infrared light source assembly 100 are spaced apart and arranged on the housing 202 . The infrared light source assembly 100 emits infrared light to assist the infrared camera 204 in performing iris recognition.

Referring to FIG. 2 , an infrared light source assembly 100 according to an embodiment of the present invention includes an infrared light source 10 , a lens 20 , and a driving assembly 30 .

The infrared light source 10 is movably disposed within the housing 202. The infrared light source 10 is configured to emit infrared light. Generally, the divergence angle of the infrared light emitted by the infrared light source 10 is less than or equal to 5 degrees. For example, the divergence angle of the infrared light can be any one of 2 degrees, 3 degrees, 3.5 degrees, 4 degrees, 4.5 degrees, and 5 degrees. The infrared light source 10 can be an infrared light emitting diode (LED).

The lens 20 can be disposed on the housing 202 and cover the infrared light source 10. The lens 20 is spaced apart from the infrared light source 10 and can move relative to it. The lens 20 is used to guide the infrared light transmitted through the lens 20 out of the infrared light source assembly 100. Specifically, the lens 20 is used to guide the infrared light transmitted through the lens 20 to the eyes of the subject to be identified outside the housing 202. The lens 20 can be a convex lens, a concave lens, a combination of multiple convex lenses, a combination of multiple concave lenses, a combination of a convex lens and a concave lens, or other optical lenses other than a glass panel (e.g., a reflector, a prism, etc.).

The drive assembly 30 includes a light source driver 32, which includes a light source driver stator 322 and a light source driver mover 324 extending from the light source driver stator 322. Specifically, the light source driver 32 can be a rotary motor, the light source driver stator 322 can be a rotary motor stator, and the light source driver mover 324 can be a rotary motor shaft. When the light source driver 32 is activated and the light source driver mover 324 rotates, the rotation of the light source driver mover 324 drives the infrared light source 10 to rotate, thereby changing the relative position of the infrared light source 10 and the lens 20, thereby adjusting the emission direction of the infrared light emitted by the infrared light source 10 and ensuring that the infrared light emitted from the lens 20 covers the eyes of the object to be identified.

Specifically, when the light source driver 32 drives the infrared light source 10 to rotate, the lens 20 always covers the infrared light source 10, and the infrared light emitted by the infrared light source 10 can be projected onto the lens 20. Moreover, the lens 20 can guide the infrared light transmitted to the lens 20 to the object to be identified, and make the unit area illumination intensity of the infrared light covering the eyes of the object to be identified high.

The electronic device 200 and the infrared light source assembly 100 of the embodiment of the present invention drive the infrared light source 10 to move through the driving assembly 30 so that the emission direction of the infrared light emitted by the infrared light source 10 after being projected through the lens 20 changes, thereby enabling the lens 20 to guide the infrared light to the target direction. Therefore, when the emission power of the infrared light source 10 is relatively small, it can also project sufficiently strong infrared light to the eyes of the object to be identified. On the one hand, the power consumption of the infrared light source 10 is reduced. On the other hand, the energy of the infrared light beam of the infrared light source 10 is relatively concentrated, the lighting intensity is relatively large, and the fill light effect is better.

The electronic device 200 and the infrared light source assembly 100 of the embodiment of the present invention also have the following beneficial effects: the divergence angle of the infrared light emitted by the infrared light source 10 is less than or equal to 5 degrees, so that the energy of the infrared light is relatively concentrated, and the intensity of the infrared light irradiated on the eyes is strong, thereby making the iris texture in the iris image of the glasses collected by the electronic device 200 clearer and more obvious.

Referring to FIG. 4 , in certain embodiments, the light source driver 32 of the aforementioned embodiment may also be a linear motor, the light source driver stator 322 may be a linear motor stator, and the light source driver mover 324 may be a linear motor shaft. When the light source driver 32 is activated and the light source driver mover 324 moves, the light source driver mover 324 drives the infrared light source 10 to change the relative position between the infrared light source 10 and the lens 20, thereby adjusting the emission direction of the infrared light emitted by the infrared light source 10 and ensuring that the infrared light covers the eyes of the subject to be identified.

Referring to FIG5 , in certain embodiments, the light source driver 32 included in the drive assembly 30 of the above embodiment can be replaced with a lens driver 34, which includes a lens driver stator 342 and a lens driver mover 344 extending from the lens driver stator 342. Specifically, the lens driver 34 can be a rotary motor, the lens driver stator 342 can be a rotary motor stator, and the lens driver mover 344 can be a rotary motor shaft. When the lens driver 34 is activated and the lens driver mover 344 rotates, the lens driver mover 344 rotates, driving the lens 20 to rotate to change the relative position of the infrared light source 10 and the lens 20, thereby adjusting the emission direction of the infrared light emitted by the infrared light source 10 and allowing the infrared light to cover the eyes of the object to be identified. Of course, referring to FIG6 , the lens driver 34 can also be a linear motor, the lens driver stator 342 can be a linear motor stator, and the lens driver mover 344 can be a linear motor shaft. When the lens driving member 34 is excited and the lens driving actuator 344 moves, the movement of the lens driving actuator 344 drives the lens 20 to move to change the relative position of the infrared light source 10 and the lens 20, thereby adjusting the emission direction of the infrared light emitted by the infrared light source 10 and making the infrared light cover the eyes of the object to be identified.

Referring to FIG. 7 , in certain embodiments, the drive assembly 30 of the above embodiment includes a lens driver 34 and a light source driver 32 . The lens driver 34 drives the lens 20 to move, and in conjunction with the light source driver 32 drives the infrared light source 10 to move, thereby jointly adjusting the emission direction of the infrared light and ensuring that the infrared light covers the eyes of the object to be identified. Specifically, the light source driver 32 and the lens driver 34 can both be linear motors, the light source driver stator 322 and the lens driver stator 342 can both be linear motor stators, and the light source driver mover 324 and the lens driver mover 344 can both be linear motor shafts. When the light source driver 32 is excited, the light source driver 324 moves, and the light source driver 324 moves to drive the infrared light source 10 to move, and the lens driver 34 is excited, the lens driver 344 moves, and the lens driver 344 moves to drive the lens 20 to move, the lens 20 always covers the infrared light source 10, and the infrared light emitted by the infrared light source 10 can be projected onto the lens 20, and the lens 20 can guide the infrared light projected onto the lens 20 to the object to be identified, and increase the unit area illumination intensity of the infrared light covering the eyes of the object to be identified.

Referring to FIG8 , the drive assembly 30 of this embodiment can also be configured as follows: the light source driver 32 can be a linear motor, the light source driver stator 322 can be a linear motor stator, and the light source driver mover 324 can be a linear motor shaft; the lens driver 34 can be a rotary motor, the lens driver stator 342 can be a rotary motor stator, and the lens driver mover 344 can be a rotary motor shaft. In other words, when the light source driver 32 is activated, the light source driver mover 324 moves, thereby driving the infrared light source 10 to move; simultaneously, when the lens driver 34 is activated, the lens driver mover 344 rotates, thereby driving the lens 20 to rotate.

Referring to FIG. 9 , the drive assembly 30 of this embodiment can also be configured as follows: the light source driver 32 can be a rotary motor, the light source driver stator 322 can be a rotary motor stator, and the light source driver mover 324 can be a rotary motor shaft; the lens driver 34 can be a linear motor, the lens driver stator 342 can be a linear motor stator, and the lens driver mover 344 can be a linear motor shaft. In other words, when the light source driver 32 is activated, the light source driver mover 324 rotates, thereby driving the infrared light source 10 to rotate; simultaneously, when the lens driver 34 is activated, the lens driver mover 344 moves, thereby driving the lens 20 to move.

Referring to FIG. 10 , the drive assembly 30 of this embodiment can also be configured as follows: the light source driver 32 can be a rotary motor, the light source driver stator 322 can be a rotary motor stator, and the light source driver mover 324 can be a rotary motor shaft; the lens driver 34 can be a rotary motor, the lens driver stator 342 can be a rotary motor stator, and the lens driver mover 344 can be a rotary motor shaft. In other words, when the light source driver 32 is activated, the light source driver mover 324 rotates, thereby driving the infrared light source 10 to rotate; simultaneously, when the lens driver 34 is activated, the lens driver mover 344 rotates, thereby driving the lens 20 to rotate.

Please refer to Figure 11. In some embodiments, the infrared light source 10 and the lens 20 of the above embodiment are relatively fixed, that is, the infrared light source 10 and the lens 20 are both fixed on the main body 102 of the infrared light source component 100. When the driving component 30 drives the main body 102 to move, that is, when the driving component 30 drives the infrared light source 10 and the lens 20 to move at the same time, the emission direction of the infrared light emitted by the infrared light source 10 after being projected through the lens 20 changes, so that the infrared light covers the eyes of the object to be identified.

Please refer to Figure 3. In some embodiments, the electronic device 200 of the above embodiment also includes a processor 206. The infrared camera 204 is used to collect a facial image of an object to be identified. The processor 206 is used to process the facial image to identify the image position of the human eye in the facial image, and determine the spatial position of the human eye in space based on the image position and the mapping relationship, and determine the required amount of movement of the infrared light source 10 and/or the lens 20 based on the spatial position and the distance between the infrared light source component 100 and the infrared camera 204. The driving component 30 drives the infrared light source 10 and/or the lens 20 to move according to the amount of movement, so that the lens 20 guides the infrared light to the target direction. The mapping relationship is the relationship between the coordinate system corresponding to the facial image and the coordinate system of the face in the spatial position.

Specifically, after the infrared camera 204 captures a facial image, the processor 206 first processes the facial image to identify the eye locations. There are various methods for identifying eye locations, such as template matching and grayscale projection. The template matching method involves translating a reference template image point by point within the search area of the facial image, traversing each location within the search area. Based on a similarity measurement principle, the correlation value between the image area at that location within the search area and the reference template is calculated. The correlation value is then used to determine whether the location is an eye. The grayscale projection method projects the grayscale image of the face horizontally and vertically, and statistically analyzes the grayscale values and their functions in the horizontal and vertical directions. Combining prior knowledge of the face and the geometric distribution of the eye, the face and eye locations corresponding to each change point are identified. A plane coordinate system X-Y is established within the field of view of the infrared camera 204, and another plane coordinate system X'-Y' is established on the facial image captured by the infrared camera 204, which has a certain mapping relationship with the plane coordinate system X-Y. In the plane coordinate system X’-Y’, each pixel in the face image has a coordinate value, so it can be mapped to the plane coordinate system X-Y to determine the corresponding position of each pixel in the field of view. When identifying the position of the human eye on the face image, since there may be multiple pixels corresponding to the human eye, one of the pixels can be selected as the pixel of the human eye position. Subsequently, the coordinates (x’, y’) of the pixel are determined in the plane coordinate system X’-Y’, and the coordinates (x, y) of the pixel in the plane coordinate system X-Y are determined based on the mapping relationship between the plane coordinate system X-Y and the plane coordinate system X’-Y’. The driving component 30 drives the infrared light source 10 and/or the lens 20 to move so that the emission direction of the infrared light emitted by the infrared light source 10 changes after being projected by the lens 20, thereby adjusting the emission direction of the infrared light. The position of the infrared light source 10 relative to the lens 20 also has a certain mapping relationship with each coordinate point in the plane coordinate system X-Y. This mapping relationship is empirical data obtained from a large number of experimental tests in the early stage. Therefore, after determining the coordinates (x, y) of the pixel point in the plane coordinate system X-Y, the required amount of movement of the infrared light source 10 and/or lens 20 can be determined based on the mapping relationship between the position of the infrared light source 10 relative to the lens 20 and the coordinate point. The driving component 30 drives the infrared light source 10 and/or lens 20 according to the movement amount to change the direction of the infrared light emitted by the infrared light source 10 after being projected through the lens 20, thereby enabling the lens 20 to guide the infrared light in the target direction. The mapping relationship is the relationship between the coordinate system corresponding to the facial image and the coordinate system of the face in spatial position. In this way, the electronic device 200 can capture an iris image with relatively clear texture.
