Claim Text:
1. An electronic device, comprising: 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, wherein 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, wherein 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, wherein 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 to capture a second sensed image for fingerprint authentication, wherein the processor activates a portion or all of the fingerprint sensing cells in the fingerprint recognition apparatus to capture the second sensed image in the operation mode, and wherein the resolution of the second sensed image is higher than that of the first sensed image.
