Description

[0001] The present invention relates to a mouse capable of recognizing a finger, and a method of measuring a finger using the finger,

The present invention relates to a method of using a mouse and a mouse, and more particularly, to a mouse capable of fingerprint recognition in a contact manner and a method of measuring a finger vein using the same.

Biometrics (biometrics) technology refers to technology that extracts and stores various kinds of human body information such as fingerprints, voices and eyes, and utilizes it as a means of personal identification through various IT devices. In the past, it was mainly used for security, but recently it has expanded. For example, it is used not only for security, but also for access control of important facilities in the country, overtime management of government offices, attendance management of employees, and school management of students. It can also be used for e-passports, Internet banking, and ATMs.

In recent years, much research has been conducted worldwide on fingerprint recognition technology for application to such application fields. In the case of fingerprint recognition, which is most widely used among biometrics, there is a problem that counterfeit can be performed as if the fingerprint is counterfeited by recognizing it with the same principle as painting. In case of moisture or foreign matter, authentication error, fingerprint damage, And misunderstandings that followed.

In addition, in the case of iris recognition, which is likely to replace fingerprint recognition, an error may occur depending on the distance and angle during authentication, and various problems such as a mistake when a color contact lens is worn, Finger recognition technology is the most popular.

The fingertip is a finger vein which is easy to recognize among the blood vessels of a person, which is irradiated with infrared light, etc., and recognizes and authenticates the pattern of the vein. It has an advantage of security related to personal information leakage accident because it can not be forged or altered because it authenticates the inside of the blood vessel and the vein pattern of the finger which does not flow blood can not be measured.

However, there is a problem that expansion or contraction of blood vessels may occur due to seasonal change, exercise, and physical activity of a person, so that an error may occur when measuring a vein, and accordingly, .

In addition, since the vein is surrounded by the skin inside the body rather than appearing on the surface of the body, it is necessary to detect the physical light characteristics such as transmission, diffusion, and absorption of light to the inside of the skin using near- Therefore, the sensitivity of the image sensor to the near-infrared ray is important, and it is necessary to be able to simultaneously photograph the dark region including the bright portion and the fine vein pattern due to the direct reflection and transmission of the light source. Therefore, in the case of an image sensor device capable of simultaneously capturing the near-infrared sensitivity of the image sensor and the bright and dark areas, it is very expensive and difficult to apply the infrared camera.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood, however, that the invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, Is provided to fully inform the user. Also, for convenience of explanation, the components may be exaggerated or reduced in size.

1A and 1B are perspective views schematically showing a mouse equipped with a contact type finger vein recognition device according to an embodiment of the present invention.

Referring to FIGS. 1A and 1B, a mouse 100 having a contact type finger vein recognition device according to an embodiment of the present invention includes a cover 200 and a main body 110, . The bottom surface (not shown) may have a flat shape to contact a mouse pad (not shown). The main body 110 may have a shape in which sidewalls protruding at a predetermined height along the edge of the bottom surface are extended. The body 110 may include electrical components (e.g., a switch, an image processing portion, a sensor portion, and a power supply portion).

FIG. 1A is a perspective view illustrating a mouse according to an embodiment of the present invention. Referring to FIG. 1A, at least two buttons 120 and 140, which are coupled to a cover 200 of a mouse, It has the ability to run your computer just like a mouse. 1B is a perspective view of a mouse 100 according to another embodiment of the present invention in which a pad 100 is coupled to a cover 200 of a mouse 100, . The structure of the mouse 100 can be variously designed according to the function of the sensor unit described later. The operation principle of the mouse and the finger vein recognition method according to an embodiment of the present invention will be described later with reference to FIGS. 2A to 2G, 3 and 4. FIG.

2A to 2G are views schematically showing a finger vein recognition method using a mouse having a contact type finger vein recognition device according to an embodiment of the present invention.

2A and 2B are sectional views of the mouse 100. Various electric components can be installed in the inner space formed by the bottom surface of the main body 110 and the side walls. For example, the electrical component may include a printed circuit board (PCB) 160, an image processing unit 170, a sensor unit 180, a power supply unit 190, and the like. The printed circuit board 160 may be disposed in the inner space of the main body 110 so as to be parallel to the bottom surface.

When the mouse 100 is operated in the scroll mode, the image processing unit 170 determines that the first light source 14-1 of the light emitting unit 14 formed in the lower portion of the mouse is dark The brightness of the first light source 14-1 can be controlled when the finger 20 comes into contact with the surface of the pad portion 13 or a change in brightness of the image occurs. Here, for example, the first light source 14-1 may be a different light source from the second light source of the light emitting portion 14 used in the finger vein recognition mode, and may be a variety of colors preferred by the user such as visible light, The light source may be directed from the bottom of the mouse 100 toward the finger 20.

The sensor unit 180 may be configured to include an image sensor separately from an optical sensor for a mouse (not shown) when the type of the mouse 100 is an optical mouse, for example. If a red LED for an optical mouse (including other visible light or near-infrared LED) is designed to illuminate the lower surface of the optical mouse and to be irradiated to the upper side with the pad portion, It can be used simultaneously as a light source for a mouse and as a light source for a scroll mode.

However, you can use only one image sensor to perform all the functions of the mouse, including finger vein recognition and photo sensor functions.

When only one image sensor is used, an effect that the configuration of the mouse 100 is simple and the cost is further reduced can be obtained. The sensor unit 180 described above may be disposed on the printed circuit board 160 provided in the main body.

A power supply unit 190 may be disposed on one side of the sensor unit 180. The power supply unit 190 may include any power supply unit, and may include, for example, a battery. For example, in the case of a wireless mouse, the power supply 190 may be a battery. On the other hand, when the weight of the mouse 100 is too light or heavy, it may be inconvenient to operate the command. Thus, the mouse 100 can be designed to have a constant mass.

The main body 110 on which the electrical components described above are installed can maintain a fixed shape. For example, the main body 110 can be manufactured by injection molding with a material such as plastic resin or metal.

The mouse 100 may further include a pad portion 13 coupled to the cover 200. The pad portion 13 can replace a wheel (not shown) which has been caused to protrude outside and inside the case of the conventional mouse, thereby increasing the volume and weight. The pad unit 13 is arranged to be parallel to the cover 200 to provide the effect of reducing the volume and weight of the mouse 100 while performing the function of the conventional wheel.

Meanwhile, the pad unit 13 may have a predetermined area so as to be able to perform an operation of moving or pressing the finger in the forward, backward, leftward or rightward direction by being in contact with the exposed surface of the cover 200 in parallel. For example, the pad portion 13 may be formed of a plate such as a rectangular plate, or one or three continuous plates. At least a part of the pad portion 13 may be formed as a light transmitting window so that the light reflected or diffused from the finger by the light source can be incident on the image sensor provided inside the mouse 100. Preferably, when the pad portions 13 are arranged as one, it is possible to perform the vein recognition function by being located at the center of the position (the position of the existing wheel) and depressing the pad portion 13 with the finger . In the case where three pad portions 13 are continuously arranged, the central pad portion 13 is made to be identical to the one pad portion, and the right and left buttons (120 and 140 in FIG. 1B) It is possible to additionally perform a function such as a moving direction of a finger, a gesture, and a button by making the finger 20 act as a wide window that can be observed.

The pad unit 13 senses contact and movement of a finger contacting the pad unit 13 and transmits the sensed contact and movement to the printed circuit board 160 so that the mouse 100 inputs a command to a computer .

Figs. 2C to 2G are enlarged views of area A indicated by the one-dot chain line in Figs. 2A and 2B. Referring to FIGS. 2C and 2E, the finger vein recognition device 10 is viewed in a direction in which the user's nail is viewed from the front. The finger vein recognition apparatus 10 includes a light emitting unit 14 having at least one light source that can largely irradiate a finger 20 of a user, a signal reflected from the skin surface of the finger 20, A signal due to the light diffused from the finger by the second light source is incident on the sensing region and the vein image of the finger 20 can be acquired by sensing the movement or the gesture of the at least one finger 20 The at least one image sensor 18 and the vein pattern of the finger are brought into direct contact with the finger 20 so that the vein pattern of the finger can be placed apart from the image sensor 18 by the focal distance D of the image sensor 18, And a frame portion 12 having a pad portion 13 capable of guiding the pad portion 13 so that the pad portion 13 can be guided. The frame part 12 may include a cover 200 and a body 110 on which electrical components may be provided.

More specifically, the light emitting unit 14 includes at least one second light source 14-2 different from the first light source 14-1 shown in FIG. 2A . The second light source 14-2 is a near-infrared LED light source, and can have, for example, a wavelength band of about 760 nm or can have a near-infrared light wavelength of about 850 nm or more (optimum wavelength of about 930 nm). The wavelength band of the light source has a high absorbance of oxygen-free hemoglobin, so that the selectivity of the finger vein pattern image obtained based on the light reflected or diffused from the finger 20 by using the wavelength band Differentiated characteristics) can be made clearer than using different wavelength bands. Alternatively, the wavelength band of the second light source 14-2 may be near infrared rays of about 850 nm or more, in which blood (liquid) containing hemoglobin absorbs light well. The second light source 14-2 can be irradiated in any direction in the three-dimensional space. Therefore, in order to prevent the second light source 14-2 from directly irradiating the image sensor 18 without passing through the user's finger 20, the light shielding film 19 may be provided, (14-2) can be projected only on the finger 20. The position of the light-shielding film 19 is not always fixed depending on the position of the light emitting portion 14 or the position of the image sensor 18, and can be designed and changed. The image sensor 18 may comprise one of a complementary metal-oxide semiconductor (CMOS) sensor or a charge-coupled device (CCD) sensor.

On the other hand, in order to operate the finger vein recognition device 10, when the finger 20 of the user is drawn into the finger vein recognition device 10, the pad portion 13 provided on the cover 200 of the mouse 100, And a switch 17 capable of supplying or blocking power to the light emitting portion 14 by the pressure of the finger 20 that is drawn into the finger 20. [ When the switch 17 is operated, power is supplied to the light emitting unit 14 and the near infrared ray LED light source can be irradiated to the drawn finger 20. At this time, the switch 17 and the light emitting portion 14 can be connected to each other by an electrical connecting member (not shown). When the user presses the finger 20 to operate the switch 17, The finger 20 can be fixed so that the finger 20 does not move while the light emitting portion 14 disposed on the left and right as a reference presses the finger 20 and measures the vein image of the finger 20. [

The cover 200 is provided with a pad portion 20 capable of guiding the position of the finger 20 so that the vein pattern of the finger 20 is in contact with the focal distance D of the image sensor 18, (13). The pad portion 13 and the switch 17 may be spaced apart from each other and the pad portion 13 may reflect light reflected from the skin of the finger 20 or diffused therein by the light source of the light emitting portion 14, And may be made of a light-transmitting material so as to be incident on the sensing area of the sensor 18. In addition, the finger vein recognition device 10 may be an open type, and the near infrared ray LED light source, as well as visible light and light of various wavelength ranges may be incident on the sensing area of the image sensor 18. In order to prevent this, the filter unit 15 may be formed under the pad unit 13. Here, the filter unit 15 may use a band-pass filter capable of transmitting only infrared rays.

In addition, when the pad portion 13 is moved in the direction of the arrow by the pressure of the finger 20 to operate the switch 17, A stopper 13b capable of stopping the button (120, 140 shown in Fig. 1B) may be formed. The stopper 13b may be formed of the same material as the light-shielding film 19 to prevent the near-infrared LED light source from being directly incident on the image sensor 18 without being irradiated onto the finger 20. [

2F and 2G are cross-sectional views of part of the configuration of the finger vein recognition device 10 as viewed from the side of the finger 20. The pad portion 13 can be fixed by the fixing portion 13a formed on one side of the pad portion 13. [ The pad portion 13 can be rotated in the direction of the arrow about the fixed portion 13a. However, the pad portion 13 is not rotated indefinitely, and the vein pattern of the finger 20 drawn into the pad portion 13 can be moved only to the region corresponding to the focal distance D of the image sensor 18. [

The switch 17 described above with reference to Figs. 2C and 2D can be formed in the direction opposite to the fixing portion 13a (i.e., the other side of the pad portion 13). When the finger 20 of the user is drawn into the finger vein recognition apparatus 10, the finger vein image can be obtained through the filter unit 15 provided on the lower surface of the pad unit 13. In addition, the support table 13 should be made of a material having excellent light transmittance for receiving the diffused image of the finger 20 by the near infrared rays without distortion and receiving the image sensor 18, and may be glass or transparent acrylic material, Since the front surface of the substrate is exposed, it may be a special material (tempered glass, etc.) within the coating to prevent scattering of light due to scratches or the like.

It is possible to move the pad portion 13 in the arrow direction by applying a force to the finger 20 after the finger 20 is drawn on the pad portion 13. [ The switch 17 can be operated by the force applied to the moved pad portion 13. [ At this time, as described above with reference to Figs. 2C and 2D, the light emitting portion 14 can be brought into direct contact with the side surface of the finger 20, and the finger 20 can be closely contacted. Power can be supplied to the tightly coupled light emitting portion 14 to emit the second light source 14-2 to irradiate the second light source 14-2 to the finger 20. The vein pattern image of the finger 20 can be obtained by fitting the vein pattern of the finger 20 to the focal distance D of the image sensor 18 and by processing or amplifying the vein pattern image of the finger 20, A vein pattern image can be obtained.

Generally, the image sensor 18 imaged the diffuse light (a portion of the vein and the diffused light shown in FIG. 2G) in the user's finger 20 due to the problem that the dynamic range is low, The portion closer to the light emitting portion 14 may be relatively bright and the portion far from the light emitting portion 14 may appear dark. Thus, the recognition rate of the finger vein may be reduced due to the brightness difference of the image. For example, when the dynamic range of the image sensor 18 is low, if the exposure value is adjusted to the dark region, the dynamic range of the bright region Or if the exposure value is adjusted to the bright area, the dark area may become black. On the other hand, when the dynamic range of the image sensor 18 is high, it is possible to take a picture at the same time regardless of the position of the exposure value. When the image sensor 18 having a high dynamic range is used, the above problems can be solved.

3 is a flowchart schematically illustrating a method of measuring a finger vein using a mouse provided with a contact type finger vein recognition device according to an embodiment of the present invention.

A step S100 of operating in a scroll mode by using a first light source of a light emitting portion formed at a lower portion of the mouse before pressing a pad portion of the center portion of the mouse with a finger, a step of switching to a finger vein recognition mode by pressing the pad portion of the center portion of the mouse with a finger (S200). As the pad unit operates, pressure is applied to the finger by the light emitting unit formed on the side surface of the finger to fix the finger. At the same time, the light emitting unit irradiates the second light source with the finger (S300) (S400) in which light diffused from the finger is incident on the sensing area of the image sensor to acquire a vein image of the finger, and after the use of the finger vein recognition mode is completed, the finger is removed or the pressure applied by the finger is removed And switching to the scroll mode by using the first light source again (S500).

The scroll mode and the finger vein recognition mode can be changed in operation through a predetermined event. For example, the pad unit formed in the center of the mouse can be operated or the finger vein recognition security program can be executed to switch between modes.

Providing the auditory information such that the nodal positions of the fingers adhering to the pad portion due to the pressure of the finger are accurately aligned and aligned with the field of view of the image sensor while the second light source is irradiated with the second light source in step S300; As shown in FIG.

Before the mouse is moved like the optical mouse, the first light source of the light emitting unit formed at the lower part of the mouse is darkened, and the finger is brought into contact with the surface of the pad unit The image processing unit formed inside the mouse can control the signal so that the function of brightening the brightness of the first light source can be controlled so that the brightness of the image changes (the screen becomes dark when the hand is placed).

4 is a view schematically showing a scroll mode operation method of a mouse having a contact type finger vein recognition device according to an embodiment of the present invention.

The mouse 100 has two modes. It is a normal mode and is a scroll mode and a finger vein recognition mode for operating a PC, a notebook computer, a tablet PC, and the like. The switching between the modes can be switched to the scroll mode or the finger vein recognition mode at any time as pressure is applied to the pad unit provided in the mouse 100.

In the scroll mode, a vector value is extracted from the moving direction of the finger by sensing the movement of the finger with the image sensor, and the vector value is matched with the mouse pointer. Also, since the focus is on the bottom surface of the finger, it is possible to operate by matching the motion of the finger with the mouse pointer by reflection image of the skin surface of the finger.

Referring to FIGS. 4A to 4E, similar to a conventional touch-type wheel mouse, it is possible to recognize a direction (vector) of an image of an image sensor, not a touch method. That is, in the scroll mode, the lens focus of the image sensor is adjusted to the skin surface position of the bottom of the finger 20, so that the movement of the finger 20 on the contact surface can be detected by the image sensor and the vector can be extracted up and down. The scroll function similar to that of the conventional touch method can be performed. For example, when the user touches the mouse 100 with the index finger and the stop finger, or moves the finger 20 up and down or left and right while the mouse is touched, the scroll function, zooming, And so on.

In addition, from the above-described principle, by using a high-resolution image sensor having a higher number of pixels of the image sensor and a wide-angle lens, it is possible to detect a gesture through multiple points of various types of fingers, A method of detecting various operations such as a left-right movement may be added.

According to the above description, the mouse device capable of finger vein recognition can be constituted by a light emitting portion having at least one light source that can irradiate a user's finger and at least one image sensor. And a frame part having a pad part capable of guiding the position of the finger in direct contact so that the vein pattern of the finger can be arranged so as to be spaced apart from the image sensor by a focal distance when the finger is drawn into the device . The frame portion may include a body having a cover and electrical components. In addition, the light emitting portion and the image sensor can be provided with variable numbers and positions in consideration of the position of the pad portion in order to accurately recognize the vein image of the finger.

The pad portion may be fixedly disposed in an obliquely inclined shape with a predetermined angle, or one side of the pad portion may be fixed by the fixing portion, and may be rotated at a predetermined angle around the fixing portion. The pad portion and the cover may be made of a material having shrinkage or expandability such as a hard rubber material so that the fingers can come into direct contact with each other comfortably.

The light emitting portion formed in the cover can be directly contacted with the finger and the sensitivity of the finger vein image can be higher than when the finger does not come into direct contact with the finger. In addition, the cover may include a light-shielding film to prevent a light source that is not reflected or diffused from the finger from directly entering the sensing area.

Further, the main body may be provided with a switch. The switch may be electrically connected to the light emitting portion using a connecting member. The power can be supplied to the light emitting portion as pressure is applied to the switch by the finger, and the power supply can be cut off by releasing the pressure to the switch.
