Abstract
The present invention provides a mobile terminal, including a terminal body having a case made of a metal, a finger scan unit disposed beneath the case and configured to detect a pressure level of external force and a fingerprint, and a controller configured to decide output intensity of an ultrasonic wave for detecting the fingerprint based on the pressure level, and to control the finger scan unit based on the output intensity.
Claims11
A mobile terminal, comprising:
- a terminal body having a case comprising metal;
- a finger scan unit located relative to an inner side of the case, wherein the finger scan unit is configured to measure pressure of an external force applied to an outer side of the case and to detect a fingerprint of a finger contacting the outer side of the case;
- and
- a controller configured to:
- identify an output intensity of an ultrasonic wave for detecting the fingerprint based on an amount of the measured pressure;
- and
- control the finger scan unit to perform the detecting of the fingerprint based on the identified output intensity of the ultrasonic wave.
