Image-capturing device having infrared filtering switchover functions

摘要

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.

1. An image-capturing device having infrared filtering switchover functions, comprising:
a first housing; at least one infrared light emitting diode disposed on the first housing and configured to emit infrared light outwardly; an image sensor disposed in the first housing and configured to receive a first light reflected from an object; an ambient light sensor disposed in the first housing and configured to receive the second light from the ambience; a filter assembly disposed in the first housing and comprising an infrared filter member being configured to filter infrared rays from the first light at a first location and a second light at a second location; and a switch module disposed in the first housing and coupled to the filter assembly, and configured to alternatively move the infrared filter member to the first location covering the image sensor and the second location covering the ambient light sensor, wherein, the infrared light is part of the first light and the second light; wherein the switch module moves the infrared filter member to the first location to cover the image sensor for filtering the infrared rays from the first light when a light intensity of the second light is higher than a predetermined threshold, and the at least one infrared light emitting diode emits infrared lights and the switch module moves the infrared filter member to the second location to cover the ambient light sensor for filtering the infrared rays from the second light when the light intensity of the second light is below the predetermined threshold.
