Abstract: This application provides a fingerprint collection apparatus. According to the fingerprint collection method and the related apparatus that are provided in this application, a sensor array is divided into a plurality of areas in terms of a column based on a quantity of input ports of an analog front end component and a quantity of columns of the sensor array, and sensor units in different areas multiplex input channels of the analog front end component by using switches. In this way, when scanning row scanning lines in the sensor array, a row scanning circuit may control the switches to output, to the analog front end component in a time division manner, original fingerprint data collected by the sensor units in the different areas, so that fewer input channels of the analog front end component can be required, and a size of a fingerprint collection apparatus can be reduced.
