An image of the bottom surface 18 is acquired through the movement of the optical mouse device moving above. In other words, the acquired image does not change when the optical mouse device does not move, and the acquired image changes when the optical mouse device moves.

In this way, the optical mouse apparatus calculates the movement amount of the optical mouse apparatus through the position calculating means 15 using the change of the acquired image. In this case, the motion estimation 14 is used to determine the degree of motion from the image. The optical mouse device emits light to the moving floor surface 18 where the optical mouse device is placed through a hole 17 formed in the bottom surface of the case 16 covering the outside of the device. At this time, the light emitting diode 13 is mainly used as a light source for emitting light. The optical mouse device also employs a structure for minimizing errors caused by light reflected directly from the bottom surface 18.

On the other hand, as a prior art, Korean Patent Application No. 2003-22936 (filed April 11, 2003) discloses the invention named "small pointing device using the surface of the finger", the case of the conventional mouse device Although a large plane for moving the mouse device is required, the structure of Patent Application No. 2003-22936 discloses that a pointing device can be implemented in a narrow space by minimizing the size of an image plane for acquiring an image. Hereinafter, the structure of Patent Application No. 2003-22936 will be described with reference to FIGS. 2 and 3.

2 is a view for explaining the configuration of a pointing device according to the prior art.

Use a way to calculate distance and direction. This approach is similar to the case where the optical mouse moves over a fixed or flat floor surface. Here, the pointer refers to an indicator moving by a pointing device such as a mouse on the screen of the display device.

For example, the structure shown in FIG. 2 is fixed in a portable terminal device, and an image which is changed into the fixed state is acquired. Specifically, for example, when moving the pointer (Pointer) displayed on the screen of the portable terminal device, has a structure made to control the pointer to the surface of the finger for ease of use. As such, the movement of the finger is made to cause the change of the image on the surface from which the image is acquired. Therefore, the direction and distance to which the pointer is to be moved can be obtained by analyzing the motion of the image generated by the movement of the finger.

7A and 7B are diagrams for describing a CMOS image sensor and an internal circuit thereof according to an exemplary embodiment of the present invention, respectively.

Specifically, the pixel structure and operation principle of the CMOS image sensor will be described with reference to FIGS. 4A and 4B.

Referring to FIG. 7A, the CMOS image sensor is composed of chips containing pixels, and includes an amplifier, an analog / digital converter, an internal voltage generator, and a timing generator in one chip. Timing generators and digital logic can also be combined, which has significant advantages in space, power, and cost savings.

In general, while the charge coupled device (CCD) is made through a specialized process, the price is expensive, whereas the CMOS image sensor can be mass-produced through a wafer process, which is less expensive than the CCD, and also has advantages in economy of scale. There is this.

Therefore, the CMOS image sensor is widely extended to digital cameras, smart phones, PDAs, notebooks, security cameras, bar code detectors, HDTV resolution cameras, toy products, and the like.

Bio-parts used in such biometrics include fingerprint, retina, iris, face, hand, vein, voice, handwriting, body smell, and DNA. It is a matrix. Here, the fingerprint recognition is a form of a constant flow by the sweat glands are raised, and since the shape is unique, the fingerprint has a characteristic that does not change for a lifetime, thus retina, iris, vein, and facial shape recognition in stability. It is used as an efficient identity verification means because it is higher than such means.

Specifically, the fingerprint recognition method captures in various ways. Currently, there are two types of fingerprint readers, an optical method (Frustrated Total Internal Reflection), a silicon chip (Silicon Chip Sensing), or a semiconductor method. The recent trend of the technology includes an optical method, based on ultrasound or a semiconductor chip. The optical method includes a CCD and a CMOS sensor, and is an early technology of fingerprint recognition and is commonly used.

First, the method using optics is the most widely used method, and a strong light is shot on the platen to reflect the fingerprint form of the fingertip placed on the platen, and the reflected fingerprint image passes through the high refractive lens and the CCD It is input to (solid-state image sensor). There is also a method of obtaining an image by projecting the image reflected from the fingerprint of the finger placed on the platen to the hologram film. The input fingerprint image is digitized by a special algorithm. In addition, there is no special method to image the shape of the fingerprint more precisely, but moisture or oil in the fingerprint itself changes the refractive index so that the fingerprint image is accurately formed on the CCD.

In addition, referring to FIG. 8A, a method using a silicon chip (semiconductor) reads a special shape of a fingerprint in contact with the chip surface as an electrical signal when the fingertip is directly contacted with the surface of the silicon chip using the electrical conduction characteristics of the skin. Will be. Fingerprint information is obtained by reading the change of the charge amount in the sensor array according to the pressure and heat of the finger placed on the chip surface, and the fingerprint is obtained by converting the fingerprint image obtained by using an electric field or ultrasonic wave into an electrical signal.

In other words, the biological properties (Biometrics) can be used as it is. This semiconductor chip method is the most stable because the algorithm may vary from manufacturer to manufacturer, but the basic structure is simple.

Meanwhile, referring to FIG. 8B, the fingerprint recognition thermal sensor includes a fingerprint scanning unit 510, a grayscale image conversion unit 520, a binary image conversion unit 530, a biometric template 540, and a comparison unit. 550, a determination unit 560, and an audit trail 570.

The grayscale image converter 520 converts the fingerprint of the scanned finger into a grayscale image, and the binary image converter 530 converts the grayscale image into a binary image.

The biometric template 540 prestores fingerprint information on a user's finger that is already registered.

The comparison unit 550 compares the binary image with the fingerprint information already registered, and the determination unit 560 determines whether the user is the user according to the compared image.

The audit trail 570 tracks whether a security breach has occurred legally and without permission, in accordance with the identity of the judge 560. Here, Audit Trail is a usage record recorded in chronological order for the use of system resources in a computer security system. This record includes user logins, file access, various other activities, and whether actual or attempted security violations occurred legally and without permission. Therefore, audit trails are a basic requirement for accountability traceability that is necessary for a secure system because it can be used to track user behavior and reveal whether security incidents are related to a specific individual's behavior.

In addition, the fingerprint recognition thermal sensor 620 of the FeelTip 600, which is the tactile information input device, serves as a small protrusion, and recognizes the protrusion of the FeelTip 600 by the human finger 300. As the finger 300 moves, the information may be fed back.

As a result, the concept of FeelTip according to an embodiment of the present invention is that the role of a touch pad and a hand is changed, in which a finger serves as a pad and a small device serves as a pen. In order to realize this concept, a small CCD image sensor is used to sense the amount of movement of the finger surface in contact with the device, and FeelTip has a small protrusion shape, so that the amount of displacement when the finger moves is fed back to the user's tactile sense. Thus, while the finger is moving, the movement and position can be recognized more accurately.

In addition, the tactile information input device according to the embodiment of the present invention can be implemented as an ultra-small (3 mm 3 mm) input device, and since the roles of the pen and the pad are reversed in the conventional touch pad, the embodiment of the present invention According to the tactile information input device according to the present invention, only a part serving as a pen can be made, thereby making it possible to make a miniature input device.

While the invention has been shown and described in connection with specific embodiments thereof, it will be appreciated that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone who owns it can easily find out.

According to the present invention, since the fingertip becomes a pad and is fed back to the person through the touch of the finger, more precise information input can be manipulated.

In addition, according to the present invention, since the user's hand movement can be accurately recognized through the touch while moving the finger, the normal movement of the finger can be recognized without seeing the motion in the eyes or the screen.

In addition, according to the present invention, since the small projection portion becomes an input device, space can be useful because it can be mounted on a curved surface or a corner rather than a plane.
