Filed: 1990-03-16
Abstract: PURPOSE:To surely confirm a fingerprint as the one of a principal by counting the number of feature points existing in the neighborhood of at least one feature point that coincides when a person is confirmed as the principal, and confirming the person as the principal when the number is within a certain threshold value. CONSTITUTION:A fingerprint image is inputted, and the pattern matching of the feature point is performed, and the number of feature points existing in the neighborhood of at least one feature point that coincides is counted, and collation is refused when the number exceeds the certain threshold value, and the person is recognized as the principal when it is within the certain threshold value. In other words, since a large number of forgery fingerprint false feature points exist, it can be judged that the fingerprint is the one of the false fingerprint when the number of feature points in the neighborhood of the feature point that coincides exceeds a certain constant value (threshold value). In such a way, it is possible to surely confirm the fingerprint as the one of the principal.

Abstract: PURPOSE:To prevent the change in video signal level and pedestal from being produced when the state of a shading correction signal waveform is changed by fixing the prescribed area part of a video in the correction signal to a fixed potential by a clamp circuit. CONSTITUTION:The output of an operational amplifier A1 is sample held in a sample and hold circuit SH1. This sample hold is carried out in the area corresponding to the center of a scanning picture. The sample and hold circuit SH1 is constituted so as to make the input and the output of the sample and hold circuit SH1 the equal potential, thereby, the area corresponding to the center of the video in the output of the operational amplifier A1 is made equal to a reference potential. In a superimposing shading correction in which the superimposition is performed to the video signal, the instantaneous value level in the correction waveform in the central area of the video is equal to the level of a fly-back period. Thereby, the pedestal level after the superimposition shading correction in this area is not changed even when the correction is performed in any waveform.
