Abstract:
1. An image capturing apparatus comprising: a frame having an aperture; a lens for collecting light allowed through by the aperture; a sensor for receiving the collected light; and an infra-red filter coupled to the frame, the infra-red filter for blocking out infra-red light, the infra-red filter being movable from a first position to a second position, wherein in the first position the infra-red filter is in an optical path between the lens and the sensor so as to not allow infra-red light to reach the sensor from the lens, and in the second position, the infra-red filter is not in the optical path between the lens and the sensor so as to allow infra-red light to reach the sensor from the lens, wherein the lens and the infra-red filter are configured such that visible light leaving the infra-red filter focuses directly on the sensor with the infra-red filter in the first position, and infra-red light leaving the lens focuses directly on the sensor with the infra-red filter in the second position, and wherein a distance between the lens and the sensor is such that the infra-red light leaving the lens is focused directly on the sensor without use of an interceding lens or filter and a thickness of the infra-red filter is such that the visible light leaving the infra-red filter is focused directly on the sensor when the infra-red filter is in the first position.
