摘要： A structure (113b) which includes an overhang and a support portion supporting substantially the center of the overhang, and in which the area of the support portion is smaller than the area of the overhang in the two-dimensional direction of an upper electrode (1110b) is formed on the upper electrode (110a) in a region above each lower electrode 105a in one-to-one correspondence with the lower electrode (105a). An object of surface shape sensing, e.g., the tip of a finger (1602) touches the surface of the overhang of the structure (113b), and the support portion of the structure (113b) whose overhang is in contact with the object of sensing pushes down a portion of the upper electrode (110a) toward the lower electrode (105a), thereby deforming the upper electrode (110a).

摘要： An image capturing apparatus includes an image capturing section and capture control section. The image capturing section converts the shape of an object into an electrical quantity in accordance with the parameter value set in a parameter setting section, and outputs image data representing an image corresponding to the shape of the object. The capture control section receives the image data output from the image capturing section, calculates an evaluation index for evaluating the image quality of the image from the image data. If the evaluation index falls outside the range of a preset reference value, the capture control section changes the parameter value set in the parameter setting section so as to make the evaluation index fall within the range of the reference value to output the image data which is received from the image capturing section and the evaluation index of which falls within the range of the reference value. An image capturing method and a fingerprint collation method and apparatus are also disclosed.

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 surface shape recognition apparatus includes a plurality of sensor electrodes, passivation film, capacitance detection circuit, and ground electrode. The sensor electrodes are formed on an interlevel insulator on a substrate and insulated from each other. The passivation film is formed on the interlevel insulator to cover the upper and side surfaces of each sensor electrode. The passivation film is formed from a dielectric material. When a target recognition object comes into contact with the surface of the passivation film, the capacitance detection circuit detects an electrostatic capacitance formed between the sensor electrode and the surface of the target recognition object opposing the sensor electrode. The ground electrode passes static electricity on the surface of the passivation film.

摘要： A surface shape recognition apparatus includes detection circuit, comparison circuit, storage circuit, and control circuit. The detection circuit electrically detects a surface shape pattern in a partial region of the target collation surface of an object using a plurality of sensor elements and outputs detection data representing the surface shape pattern. The comparison circuit compares the detection data from the detection circuit with predetermined collation data and outputs a comparison result. The storage circuit stores template data representing the surface shape pattern of the entire target collation surface, the template data being obtained from the object in advance. The control circuit partially reads out, as collation data, the template data stored in the storage circuit from an arbitrary position, outputs the collation data to the comparison circuit, and performs determination for authentication between the template data and the object on the basis of the comparison result from the comparison circuit. A surface shape recognition method is also disclosed.
