摘要： A capacitance sensor used as a fingerprint sensor is provided which includes, in addition to a sensor array (11) in which sensor cells (100) each with a sense electrode are disposed in the form of an array, a canceling dummy block (14) having, disposed in an area having no relation with any object under detection, one column of dummy cells (141) corresponding to each row in the sensor array (11) and each having a dummy electrode nearly identical in parasitic capacitance to the sense electrode of the sensor cell (100). Also, a differentiation output unit (183) is provided to differentiate between a sensed voltage Vsig sensed at the sensor array (11) by sensing circuit (13) and sensed voltage Vdmy sensed at the canceling dummy block (14), thereby eliminating the influence of a variation in parasitic capacitance Cp, caused by a production tolerance.

摘要： An image verification system including a fingerprint sensing means for sensing a fingerprint; an image data storing means for storing image data of the fingerprint sensed by the fingerprint sensing means as first image data; and a residual fingerprint judging means for comparing second image data of a fingerprint newly sensed by the fingerprint sensing means with the first image data stored by the image data storing means, and judging whether or not the second image data indicates a residual fingerprint, wherein the residual fingerprint judging means judges that the second image data indicates a residual fingerprint and does not verify the fingerprint when said first image data and the second image data match, while judges that the second image data is not a residual fingerprint and verifies the fingerprint when the first image data and the second image data do not match, whereby a fingerprint can be verified with a high precision without erroneously detecting a residual fingerprint.

摘要： When a current charge method is used as a method of detecting capacitance, there poses a problem in which S/N is deteriorated by a dispersion in element characteristics of a cell to be detected and when a voltage charge method is used, since parasitic capacitances of column sense lines are very large and accordingly, there is needed some devise for sampling electric charge charged to the capacitance. There are arranged unit cells having detection electrodes and cell selecting switches connected between the detection electrodes and column sense lines in an array shape, electric charge is charged from detecting circuits to the detection electrodes under constant charge voltage, and thereafter, the column sense lines are imaginarily grounded to thereby detect the capacitances formed between the detection electrodes and the surface of the finger in accordance with recesses and projections of a fingerprint via the column sense lines.
