Title: Reference point extracting method for fingerprint
Inventor: NAKAJIMA TATESHI
IPC: G06T7/00
Filed: 1991-07-04
Abstract: PURPOSE:To easily count the number of ridge lines by calculating the maximum maximal value among values concerning both directions and defining the intersection of these maximal values as a reference point. CONSTITUTION:A ridge line R is displayed with graphic luminance, and the other part is displayed with background luminance. In order to obtain binary image, processing such as noise removal, shading correction and optimum threshold value calculation, etc., are suitably executed. The fingerprint image is scanned in X and Y directions, and the intersection between scan lines L1 and L2 and the ridge line is calculated. Therefore, a representative numerical value showing the number of ridge lines can be directly calculated from the binary image without turning the ridge line to a thin line. In this case, as a method for judging the edge of the ridge line, a point changing the luminance from the background luminance to the graphic luminance, a point changing the luminance from the graphic luminance to the background luminance or both points are adopted. The feature of distribution at that time is equivalent.

Abstract: PURPOSE:To facilitate countermeasure even in using a general bearing and to easily control the rotation of a driving motor by driving a polygon mirror so that it is integrally rotated with the rotor of a 2nd rotating motor whose stator is fixed to the rotor of a 1st rotating motor. CONSTITUTION:A fly-wheel 3 is fixed to one end of the rotating shaft 2 of the 1st rotating motor 1 and the stator 5 of the 2nd rotating motor 4 is fixed to the other end thereof. The center shaft 6 of the stator 5 is integrally constituted with the rotating shaft 2 of the 1st rotating motor 1 and the peripheral wall of a rotor housing 10 in the 2nd rotating motor 4 is formed, for example, in a hexahedral polygon mirror 14. Considering horizontal scanning in an NTSC system by means of the hexahedral polygon mirror, high-speed rotation is needed in the case of driving the polygon mirror with a single motor. However, the speed of rotation of the 1st and the 2nd rotating motors 1 and 4 can be set extremely low in the title device. Thus, the general bearing can be used because of the low-speed rotation and the rotation of the respective motors can be easily controlled.
