Patent ID: 7043061

Claim:
A biometric sensing device having a sensing pad for accepting a biological surface, said sensing pad having a plurality of sensing elements, said plurality of sensing elements forming sets of rows and sets of columns, said rows and said columns each having at least two sensing elements, each two of said rows and each two of said columns being individually spaced from each other, said rows and said columns grouped together to form linear sensing arrays, the biometric sensing device comprising: a first linear sensing array, the first linear sensing array being regularly spaced and having a first known spacing between rows thereof; and a second linear sensing array, the second linear sensing array being regularly spaced and having a second known spacing between rows thereof; wherein the first and second regularly spaced linear sensing arrays are separated by a third spacing that is other than an integer multiple of the first known spacing whereby interleaving of images from said first and second linear arrays during image reconstruction of a sensed biometric surface increases the resolution of a resultant interleaved image compared to the resolution of images provided independently by said first and second linear arrays.
