Abstract
Patente de Invenção: <B>"PROCESSO E DISPOSITIVO PARA CAPTAçãO CAPACITIVA DE IMAGEM"<D>. Em um sensor para captação capacitiva de imagens, especialmente de imagens de impressões digitais, os condensadores (C 12) associados a cada ponto de imagem são complementados por eletrodos de referência, que estão capacitivamente acoplados entre si por meio de capacitâncias de acoplamento (CK). Uma captação paralela da imagem por meio dos eletrodos de medição previstos e dos eletrodos de referência adicionais fornece, por um lado, uma imagem subdividida em correspondência à retícula, e por outro lado é tirada uma média local resultante do acoplamento capacitos, que é aproveitada como valor de referência local.
