The present invention discloses a fingerprint detection apparatus and a mobile terminal. The fingerprint detection apparatus comprises a capacitive fingerprint sensor and a capacitive touch control chip which is electrically connected to the capacitive fingerprint sensor; wherein the capacitive fingerprint sensor is configured to collect fingerprint information and convert the fingerprint information to an analog signal; and the capacitive touch control chip is configured to convert the analog signal to a digital signal, and generate fingerprint image information according to the digital signal. As compared with the dedicated control chip in the related art, the capacitive touch control chip has mature design and manufacture technique, and thus the manufacture and application costs are lower. Particularly when the fingerprint detection apparatus is applied in a capacitive touch control terminal, the capacitive touch control chip of the capacitive touch control terminal may be used to achieve detection and identification of the fingerprint, which significantly improves the technical integration and reduces the application cost.
