Abstract: In a method of operating a three-dimensional image sensor including a light source module according to example embodiments, the three-dimensional image sensor detects a position change of an object by generating a two-dimensional image in a low power standby mode. The three-dimensional image sensor switches a mode from the low power standby mode to a three-dimensional operating mode when the position change of the object is detected in the two-dimensional image. The three-dimensional image sensor performs gesture recognition for the object by generating a three-dimensional image using the light source module in the three-dimensional operating mode.
