Abstract
An optical sensor device includes a pixel array and a control circuit. The pixel array has pixel units arranged in N rows and M columns, and a pixel unit comprises: a photo transistor, configured to capture and generate a first image signal during a first shutter exposure time interval of a first time and to capture and generate a second image signal during a second shutter exposure time interval of a second time, the first time and the second time being consecutive; a first integration capacitor, coupled to the photo transistor, for storing the first image signal; and a second integration capacitor, coupled to the photo transistor, for storing the second image signal. The control circuit performs a motion detection to determine whether a motion occurs according to a difference between the two image signals.
