A method of initiating a calibration operation of an optical fingerprint sensing device comprising an array of photosensitive elements for capturing a fingerprint pattern, the method comprising acquiring information indicative of a change of an environmental parameter influencing the operation of the fingerprint sensing device; and if the change is larger than a predetermined threshold value, performing a calibration operation of the fingerprint sensing device. There is also provided a fingerprint sensing device configured to perform the method, and a consumer electronic device comprising such a fingerprint sensing device.

Method and system for calibration of an optical fingerprint sensing device

There is provided a method of initiating a calibration operation of a fingerprint sensing device comprising an array of sensing elements for sensing a fingerprint pattern, the method comprising acquiring information indicative of a change of an environmental parameter influencing the operation of the fingerprint sensing device; and if the change is larger than a predetermined threshold value, performing a calibration operation of the fingerprint sensing device. There is also provided a method of initiating a calibration operation of a fingerprint sensing device comprising an array of sensing elements for sensing a fingerprint pattern, the method comprising: receiving information indicative of an event in a device in which the fingerprint sensing device is arranged; if the event is one of a group of predetermined events, performing a calibration operation of the fingerprint sensing device.

Method and system for calibration of a fingerprint sensing device

An apparatus comprising a controller, wherein said controller is arranged to receive input referring to a key and identifying a touch point; display a first set of candidates comprising a plurality of candidates arranged around the touch point; receive input referring to a first candidate being comprised in said first set; receive a select command of said first candidate; and input said selected candidate as text.
