Patent attributes
An electronic device is provided. The electronic device includes: a processor; a fingerprint recognition apparatus comprising a plurality of fingerprint sensing cells and a plurality of touch sensing cells; and a housing, wherein the processor is installed inside the housing. When an application executed by the processor does not utilize the fingerprint recognition apparatus, the processor controls the fingerprint recognition apparatus to enter a power-down mode to turn off the fingerprint sensing cells and the touch sensing cells. When the processor receives a fingerprint recognition request signal from the application, the processor further controls the fingerprint recognition apparatus to enter a power-saving mode to capture a first sensed image. When the processor determines that the first sensed image is a fingerprint image, the processor further controls the fingerprint recognition apparatus to enter an operation mode.
