A detection system comprises a light source configured to illuminate an object, an image sensor configured to receive light reflected from the object, and a processor. The image sensor generates a first picture when the light source is turned on. The image sensor generates a second picture when the light source is turned off. The processor is configured to subtract the second picture from the first picture for determining an object image produced by the object.

Detection system

There is provided a click-event detection device including a light source, a light control unit, an image sensor and a processing unit. The light control unit is configured to control the light source to illuminate a finger. The image sensor receives reflected light from the finger to accordingly output a plurality of bright image frames and dark image frames. The processing unit is configured to calculate a differential image characteristic between the bright image frames and the dark image frames, to determine a plurality of operating states according to the differential image characteristic, to count a residence time at each of the operating states, and to identify a click-event according to the operating states and the residence time.

Click-event detection device

An image sensor includes a sensor matrix including a plurality of sensing elements and a plurality of shutter control lines. Each sensing element includes an electronic shutter and a photo-detector, wherein the electronic shutter controls the exposure time of the photo-detector. Each shutter control line couples to a row or column of the electronic shutters, whereby different rows or columns of the electronic shutters can be independently controlled, and the photo-detectors in the same row or column can have the same exposure time.
