Title:
An electric field type fingerprint authentication unit, the state control method for the same, a prosthetic device authentication method
Document Type and Number:
Japanese Patent JP6212648
Kind Code:
B2
Abstract:
Provided are an electric field type fingerprint identification apparatus and a state control method and a prosthesis identification method. The electric field type fingerprint identification apparatus includes a signal acquisition module and a signal processing module. In a case that a measuring state signal processing unit is electrically connected to a signal acquisition unit, a to-be-measured state signal processing unit is at least electrically connected to at least one signal acquisition unit peripheral to the signal acquisition unit in a measuring state. Charging and discharging processes of sensing capacitors electrically connected to the measuring state signal processing unit and the to-be-measured state signal processing unit are coordinated to restrain charging and discharging quantities of a parasitic capacitor between the signal acquisition unit in the measuring state and the signal acquisition unit in a to-be-measured state.
