Abstract
An electronic device includes: a wireless communication module configured to perform wireless communication in a first state; a fingerprint sensor configured to sense a fingerprint in a second state; and at least one processor electrically connected to the wireless communication module and the fingerprint sensor, wherein the processor changes the first state or the second state based on at least part of an operating state of the wireless communication module or the fingerprint sensor.
Claims21
An electronic device comprising:
- a display configured to display a video at a first framerate;
- a wireless communication module configured to perform wireless communication in a first state;
- a fingerprint sensor configured to sense a fingerprint in a second state;
- and
- at least one processor electrically connected to the display, the wireless communication module, and the fingerprint sensor,
- wherein the processor:
- receives a first signal for notifying an operation of the fingerprint sensor,
- when the first signal is received, reduces the first framerate to a second framerate, and
- when driving of the fingerprint sensor is terminated, returns to display the video at the first framerate.
6 more elements
A method for driving a fingerprint sensor in an electronic device, the method comprising:
- displaying a video at a first framerate;
- performing wireless communication, by a wireless communication module functionally connected to the electronic device in a first state;
- sensing a fingerprint, by a fingerprint sensor functionally connected to the electronic device in a second state;
- receiving a first signal for notifying an operation of the fingerprint sensor;
- when the first signal is received, reducing the first framerate to a second framerate;
- and
- when the driving of the fingerprint sensor is terminated, returning to display the video at the first framerate.
