Abstract: A gesture recognition method for a motion sensing detector is disclosed and includes the following steps: activating the motion sensing detector of an electronic device; switching the electronic device from a first input mode into a second input mode when the motion sensing detector detects a first motion generated by at least one finger of a user; and executing an operation when the motion sensing detector detects a second motion generated by the at least one finger of the user in the second input mode.

Abstract: A sensing device provided in the present invention includes a first sensor, a second sensor, a synchronizer, and a combiner. The first sensor has a first resolution and is configured to generate a first image data stream. The second sensor has a second resolution and is configured to generate a second image data stream. The second resolution is different from the first resolution. The synchronizer is electrically coupled to the first sensor and the second sensor and configured to control timing sequences of the first image data stream and the second image data stream such that the first image data stream and the second image data stream have synchronized vertical synchronization signals. The combiner is configured to combine the first image data stream and the second image data stream to form an output data stream.
