摘要： A sensor cell includes a sensor electrode (101) formed on a substrate (100), a signal output unit (16) which outputs a signal corresponding to a capacitance (Cf) formed between the sensor electrode and the surface of a finger (3), a high-sensitivity electrode (103) formed on the substrate so as to be insulated and isolated from the sensor electrode, and a potential controller (14) which controls the potential of the finger surface via a capacitance (Cc) formed between the high-sensitivity electrode and the finger surface by controlling the potential of the high-sensitivity electrode. In this arrangement, when the resistance of the finger is high, the potential of the finger surface can be controlled so as not to fluctuate with the potential change of the sensor electrode. This makes it possible to increase the sensitivity of detection of the capacitance formed between the sensor electrode and the finger surface, so ridges and valleys of the finger surface can be clearly discriminated by outputs from a plurality of sensor cells.

摘要： A master latch (1) is formed from a static circuit, and a slave latch (2) is formed from a dynamic circuit. The number of circuit elements can be smaller as compared to a slave latch formed from a static circuit so that the size and area of a master-slave flip-flop can be reduced. Since the master latch is formed from a static circuit, data can be held stably during the standby time by setting the master latch in a data holding state.

摘要： A first control potential setting means (1) generates a first control potential (N2) which reverses the magnitude relationship with a second control potential (N3) when an input signal (IN) reaches the vicinity of a logical threshold value. A second control potential setting means (2) generates the second control potential (N3) which changes in the same direction as the input signal (IN), in accordance with a change in input signal (IN). An output means (3) includes transistors (Q5, Q6), and generates an output signal (OUT) having a predetermined potential on the basis of the first control potential (N2), the second control potential (N3), and a reset signal (RSET). A reset means (4) turns off the transistor (Q6) while a waveform shaping circuit is in operation.

摘要： An image collation apparatus includes a collation unit, minimum coincidence ratio extraction unit, and determination unit. The collation unit obtains a coincidence ratio between first and second images within a printing element range for each collation unit by collating the first and second images with each other. The minimum coincidence ratio extraction unit obtains a minimum coincidence ratio from coincidence ratios obtained from the collation unit. The determination unit determines that the first and second images are identical, if the extracted minimum coincidence ratio is smaller than a predetermined threshold. An image collation method is also disclosed.
