Abstract
A reading device and a reading method for a fingerprint sensor are provided. The reading device includes a switching circuit, a plurality of analog front end (AFE) circuits and a calculation circuit. The switching circuit is coupled to a plurality of pixel units of the fingerprint sensor. The AFE circuits are coupled to the switching circuit. The calculation circuit is coupled to the AFE circuits for calculating a plurality of pixel data of the pixel units. For a first pixel unit among the pixel units, the calculation circuit reads the first pixel unit by using different AFE circuits among the AFE circuits, so as to obtain a plurality of first original sensing values of the first pixel unit. The calculation circuit calculates the pixel data of the first pixel unit according to the plurality of first original sensing values.
