Problems solved by technology

Since the previous technology uses visible light images as image recognition input when the ambient light is sufficient, when the color of the intruder’s clothing is the same or similar to the color of the environmental background, the difference between the intruder and the environmental background cannot be clearly identified in the visible light image, and Unable to detect intruders in real time

Abstract

The invention provides an image capturing device and an image capturing method. The image capturing device comprises an image capturing unit, a filtering module, a light sensing unit, an infrared light source and a processing unit. The filtering module is arranged near the image capturing unit. The filtering module comprises a first filter lens and a second filter lens. The first filter lens is used for filtering out infrared rays and allowing visible light to pass through. The second filter lens is used for filtering out the visible light and allowing the infrared rays to pass through. The light sensing unit is used for sensing the ambient light. When the processing unit determines that the ambient light intensity is higher than a threshold, the processing unit alternatively switches the first filter lens and the second filter lens to the front side of the image capturing unit, controls the image capturing unit to capture a visible light image through the first filter lens and controls the image capturing unit to capture an infrared image through the second filter lens. The image capturing device performs differential identification through front and back images and can also identify faces, objects, plate numbers or other specific information in a single image.

Description

technical field [0001] The invention relates to an image capture device and an image capture method, in particular to an image capture device and an image capture method that alternately switch two filters when the ambient light is sufficient. Background technique [0002] Most traditional monitors will add a filter switching mechanism in front of the lens to switch between filter A and filter B according to the intensity of ambient light, where filter A is used to filter out infrared rays and allow visible light Pass, and filter B allows light of all wavelengths (including visible light and infrared) to pass through. When the ambient light is sufficient, the prior art switches the filter A to the front of the lens to capture visible light images. Next, output the visible light image to image recognition software for analysis and judgment. On the contrary, when the ambient light is insufficient, the prior art switches the filter B to the front of the lens, and turns on the...
