Facilitating dynamic adjustment of a click/unclick threshold corresponding to a force-based tactile sensor is presented herein. A system can comprise a tactile sensor comprising force-based sensor(s); and a motion detection component that can determine a rate of change of a movement that has been detected via a group of sensors comprising the force-based sensor(s), and based on the rate of change of the movement, modify a defined sensitivity of the force-based sensor(s) with respect to detection of a click and/or unclick event corresponding to the tactile sensor. Further, the motion detection component can decrease the defined sensitivity with respect to detection of the click and/or unclick event in response to the rate of change being determined to satisfy a defined condition representing an increase in the speed at which the stylus or the finger has moved across the tactile sensor.

A method for fingerprint image processing includes the following. A second region of a screen and an effective collection region of an under-screen fingerprint module are determined in response to a fingerprint collection instruction. The second region is lit up; where emitted lights of the second region are associated with first optical noise, second optical noise, and first lights; the first optical noise includes reflected lights which are lights reflected by the second lights from the screen, and the second lights are part of the emitted lights travelling along a positive direction of a Z axis of the screen; the second optical noise includes direct lights which are part of the emitted lights travelling along a negative direction of the Z axis; the first lights are emitted lights reflected by a user's fingerprint. A fingerprint image is obtained by collecting and processing the first lights in the effective collection region.
