2 is a block diagram showing a pointing device according to the present invention. As shown in FIG. 2, light generated from the light emitting means 120 of the pointing device 100 is reflected on the finger surface on the image acquisition surface 110, and the light is reflected according to the pattern of the finger surface. . Light reflected from the surface of the finger forms an image on the light receiving means 130 through the image forming means 140. The formed image is converted into a digital fingerprint image by the light receiving means 130.

Such fingerprint image acquisition is performed continuously at a very high speed on the time axis. When the 2D motion and the fingerprint image are detected from the light receiving means 130 and the data is sent to the motion detecting means 150, the wireless communication means 170 transmits the data of the motion detecting means 150. In addition, when the fingerprint authentication function is added, the wireless communication means 170 detects a two-dimensional motion and a fingerprint image from the light receiving means 130 and sends data to the motion detecting means 150 and the fingerprint comparing means 160. Transmits the data of the movement detecting means 150 and the fingerprint comparing means 160.

The data transmitted from the pointing device 100 is received by the wireless communication unit 190 of the PC 180 to freely move the pointer on the screen.

The pointing device 100 includes an image acquisition surface 110, a light emitting unit 120, a light receiving unit 130, an image forming unit 140, a motion detecting unit 150, a fingerprint comparing unit 160, and a wireless communication unit ( 170).

The light emitting unit 120 is a device that emits light by controlling a pointer to be moved. The light emitting unit 120 may employ a light emitting diode, a laser diode, or an organic electroluminescence (EL).

The image acquisition surface 110 is a device that acquires motion data by receiving light illuminated from the light emitting means 120. The image acquisition surface 110 uses a transparent member formed of a transparent and flat surface where the finger contacts, while maintaining a constant distance between a subject such as a finger and the image forming surface of the image forming unit 140.

The housing having the transparent member is coated to prevent damage or contamination of the image acquisition surface 110. In addition, the image acquisition surface 110 may be a virtual plane spaced apart from the imaging means 140 by a predetermined distance.

The imaging unit 140 collects light reflected from the image acquisition surface 110 by light emitted from the light emitting unit 120 to a subject such as a finger and forms an image on the opposite side. The imaging means 140 includes an optical lens and uses a lens using a spherical surface, an aspherical surface or a hologram.

The light receiving unit 130 is an apparatus that detects an analog image collected by the imaging unit 140 and converts the analog image into a digital image. The light receiving unit 130 includes an optical sensor array in which a plurality of complementary metal oxide semiconductor (CMOS) image sensors or a charge coupled device (CCD) image sensor are two-dimensionally arranged, and is small in size to be suitable for small portable devices. A fingerprint image is produced.

The motion detecting unit 150 is a device for detecting the degree of motion through the digital image received from the light receiving unit 130. The motion detecting unit 150 determines the degree of movement of the fingerprint by calculating displacement data (direction and distance) of the feature point according to the movement of the fingerprint using a motion estimation method. The motion detecting means 150 uses a motion tracker.

The fingerprint comparator 160 compares feature points of the fingerprint image transmitted from the light receiving means 130 with the fingerprint of the user, which is previously stored, and determines whether the current user is a registered user or an unregistered user.

Here, the image acquisition surface 110, the light emitting means 120, the light receiving means 130, the imaging means 140, the motion detecting means 150, and the fingerprint comparing means 160 are preferably integrally sealed.
