An image-capturing device having infrared filtering switchover functions includes an infrared light emitting diode, an image sensor, an ambient light sensor, an infrared filter member and a switch module. The infrared light emitting diode emits infrared lights outwardly. The image sensor receives a reflection light reflected from an object. The ambient light sensor receives an ambient light. The infrared filter member filters infrared rays from the reflection light at a first location or the ambient light at a second location. The switch module is coupled to the infrared filter member, and can alternatively move the infrared filter member to the first location and the second location. The infrared lights are part of the reflection light and the ambient light.
